", "abstract": "Hot dust-obscured galaxies (Hot DOGs) are among the most luminous galaxies in the universe. Powered by highly obscured, possibly Compton-thick, active galactic nuclei (AGNs), Hot DOGs are characterized by spectral energy distributions that are very red in the mid-infrared yet dominated by the host galaxy stellar emission in the UV and optical. An earlier study identified a subsample of Hot DOGs with significantly enhanced UV emission. One target, W0204\u20130506, was studied in detail and, based on Chandra observations, it was concluded that the enhanced emission was most likely due to either extreme unobscured star formation (star formation rate > 1000 M_\u2299 yr\u207b\u00b9) or to light from the highly obscured AGN scattered by gas or dust into our line of sight. Here, we present a follow-up study of W0204\u20130506 as well as two more Hot DOGs with excess UV emission. For the two new objects we obtained Chandra/ACIS-S observations, and for all three targets we obtained Hubble Space Telescope/WFC3 F555W and F160W imaging. The analysis of these observations, combined with multiwavelength photometry and UV/optical spectroscopy suggests that UV emission is most likely dominated by light from the central highly obscured, hyperluminous AGN that has been scattered into our line of sight, by either gas or dust. We cannot decisively rule out, however, that star formation or a second AGN in the system may significantly contribute to the UV excess of these targets.", "date": "2020-07-10", "date_type": "published", "publication": "Astrophysical Journal", "volume": "897", "number": "2", "publisher": "American Astronomical Society", "pagerange": "Art.

", "abstract": "Two decades of effort have been poured into both single-dish and interferometric millimeter-wave surveys of the sky to infer the volume density of dusty star-forming galaxies (DSFGs, with SFR>100M\u2299 yr^(\u22121)) over cosmic time. Though obscured galaxies dominate cosmic star-formation near its peak at z\u223c2, the contribution of such heavily obscured galaxies to cosmic star-formation is unknown beyond z\u223c2.5 in contrast to the well-studied population of Lyman-break galaxies (LBGs) studied through deep, space- and ground-based pencil beam surveys in the near-infrared. Unlocking the volume density of DSFGs beyond z>3, particularly within the first 1 Gyr after the Big Bang is critical to resolving key open questions about early Universe galaxy formation: (1) What is the integrated star-formation rate density of the Universe in the first few Gyr and how is it distributed among low-mass galaxies (e.g. Lyman-break galaxies) and high-mass galaxies (e.g. DSFGs and quasar host galaxies)? (2) How and where do the first massive galaxies assemble? (3) What can the most extreme DSFGs teach us about the mechanisms of dust production (e.g. supernovae, AGB stars, grain growth in the ISM) <1 Gyr after the Big Bang?

The S2CSS covered over 0.33\u2009deg^2 to an average depth of \u03c3_(850) \u2248 12 mJy\u2009beam^(\u22121). Here we present a sample of 97 bright 850-\u03bcm point sources selected from the S2CSS that are potentially gravitationally lensed, and eight sources for which the strong submillimetre emission is co-located with the central brightest cluster galaxy (BCG). We construct far-infrared spectral energy distributions for those sources with Herschel SPIRE coverage and use these distributions to estimate the redshifts and luminosities of the sources. The bright submillimetre flux density of our sources makes them excellent targets for detailed follow-up work that will allow the detection of spectral features in the submillimetre/millimetre that would otherwise be too faint to detect. Through a stacking analysis, we also investigate the average submillimetre/radio properties of BCGs, determining the average 850-\u03bcm flux of BCGs as a function of radio luminosity.", "date": "2019-04", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "484", "number": "2", "publisher": "Royal Astronomical Society", "pagerange": "2757-2778", "id_number": "CaltechAUTHORS:20190411-135415330", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20190411-135415330", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Royal Society" }, { "agency": "Science and Technology Facilities Council (STFC)", "grant_number": "ST/P00541/1" }, { "agency": "European Research Council (ERC)", "grant_number": "321334" }, { "agency": "Science and Technology Facilities Council (STFC)", "grant_number": "ST/P000J41/1" }, { "agency": "Chinese Academy of Sciences", "grant_number": "XDB09000000" } ] }, "doi": "10.1093/mnras/stz011", "primary_object": { "basename": "stz011.pdf", "url": "https://authors.library.caltech.edu/records/mqsf5-sxb09/files/stz011.pdf" }, "resource_type": "article", "pub_year": "2019", "author_list": "Cheale, Ryan A.; Geach, James E.; et el." }, { "id": "https://authors.library.caltech.eduhttps://authors.library.caltech.edu/records/s5eek-v2115", "eprint_id": 91369, "eprint_status": "archive", "datestamp": "2023-08-19 12:52:38", "lastmod": "2023-10-19 22:27:20", "type": "article", "metadata_visibility": "show", "creators": { "items": [ { "id": "D\u00edaz-Santos-T", "name": { "family": "D\u00edaz-Santos", "given": "T." }, "orcid": "0000-0003-0699-6083" }, { "id": "Assef-R-J", "name": { "family": "Assef", "given": "R.

We report spectroscopic imaging of a multiple merger event in the most luminous known galaxy, WISE J224607.56\u2212052634.9 (W2246\u22120526), a dust-obscured quasar at redshift 4.6, 1.3 billion years after the Big Bang. Far-infrared dust continuum observations show three galaxy companions around W2246\u22120526 with disturbed morphologies, connected by streams of dust likely produced by the dynamical interaction. The detection of tidal dusty bridges shows that W2246\u22120526 is accreting its neighbors, suggesting that merger activity may be a dominant mechanism through which the most luminous galaxies simultaneously obscure and feed their central supermassive black holes.", "date": "2018-11-30", "date_type": "published", "publication": "Science", "volume": "362", "number": "6418", "publisher": "American Association for the Advancement of Science", "pagerange": "1034-1036", "id_number": "CaltechAUTHORS:20181130-125202344", "issn": "0036-8075", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20181130-125202344", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "W.

", "abstract": "Interferometric observations have demonstrated that a significant fraction of single-dish submillimetre (submm) sources are blends of multiple submm galaxies (SMGs), but the nature of this multiplicity, i.e. whether the galaxies are physically associated or chance projections, has not been determined. We performed spectroscopy of 11 SMGs in six multicomponent submm sources, obtaining spectroscopic redshifts for nine of them. For an additional two component SMGs, we detected continuum emission but no obvious features. We supplement our observed sources with four single-dish submm sources from the literature. This sample allows us to statistically constrain the physical nature of single-dish submm source multiplicity for the first time. In three (3/7, or 43^(+39__(\u221233) per cent at 95 percent confidence) of the single-dish sources for which the nature of the blending is unambiguous, the components for which spectroscopic redshifts are available are physically associated, whereas 4/7 (57^(+33)_(\u221239) per cent) have at least one unassociated component. When components whose spectra exhibit continuum but no features and for which the photometric redshift is significantly different from the spectroscopic redshift of the other component are also considered, 6/9 (67^(+26)_(\u221237) per cent) of the single-dish sources are comprised of at least one unassociated component SMG. The nature of the multiplicity of one single-dish source is ambiguous. We conclude that physically associated systems and chance projections both contribute to the multicomponent single-dish submm source population. This result contradicts the conventional wisdom that bright submm sources are solely a result of merger-induced starbursts, as blending of unassociated galaxies is also important.", "date": "2018-05-11", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "476", "number": "2", "publisher": "Royal Astronomical Society", "pagerange": "2278-2287", "id_number": "CaltechAUTHORS:20180509-152638878", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180509-152638878", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Simons Foundation" }, { "agency": "NASA/JPL/Caltech" }, { "agency": "Fondo Nacional de Desarrollo Cient\u00edfico y Tecnol\u00f3gico (FONDECYT)", "grant_number": "1171710" }, { "agency": "National Science Centre (Poland)", "grant_number": "2015/19/P/ST9/04010" }, { "agency": "Marie Curie Fellowship", "grant_number": "665778" }, { "agency": "W.

", "abstract": "Hot dust-obscured galaxies (Hot DOGs) are a population of hyper-luminous infrared galaxies identified by the Wide-field Infrared Survey Explorer (WISE) mission from their very red mid-IR colors, and characterized by hot dust temperatures (T > 60 K). Several studies have shown clear evidence that the IR emission in these objects is powered by a highly dust-obscured active galactic nucleus (AGN) that shows close to Compton-thick absorption at X-ray wavelengths. Thanks to the high AGN obscuration, the host galaxy is easily observable, and has UV/optical colors usually consistent with those of a normal galaxy. Here we discuss a sub-population of eight Hot DOGs that show enhanced rest-frame UV/optical emission. We discuss three scenarios that might explain the excess UV emission: (i) unobscured light leaked from the AGN by reflection over the dust or by partial coverage of the accretion disk; (ii) a second unobscured AGN in the system; or (iii) a luminous young starburst. X-ray observations can help discriminate between these scenarios. We study in detail the blue excess Hot DOG WISE J020446.13\u2013050640.8, which was serendipitously observed by Chandra/ACIS-I for 174.5 ks. The X-ray spectrum is consistent with a single, hyper-luminous, highly absorbed AGN, and is strongly inconsistent with the presence of a secondary unobscured AGN. Based on this, we argue that the excess blue emission in this object is most likely either due to reflection or a co-eval starburst.

The sample was selected from the Wide-field Infrared Survey Explorer with extremely steep (red) mid-infrared colors and with compact radio emission from NVSS/FIRST. Twenty-six sources are detected at 870 \u03bcm, and we find that the sample has large mid- to far-infrared luminosity ratios, consistent with a dominant and highly obscured quasar. The rest-frame 3 GHz radio powers are 24.7 < log (P_(3.0 GHz)/W Hz^(-1)) and all sources are radio-intermediate or radio-loud. BH mass estimates are 7.7 < log(M_(BH)/M_\u2299) < 10.2. The rest-frame 1\u20135 \u03bcm spectral energy distributions are very similar to the \"Hot DOGs\" (hot dust-obscured galaxies), and steeper (redder) than almost any other known extragalactic sources. ISM masses estimated for the ALMA-detected sources are 9.9 < log (M_(ISM)/M_\u2299) < 11.75 assuming a dust temperature of 30 K. The cool dust emission is consistent with star formation rates reaching several thousand M_\u2299 yr^(\u22121), depending on the assumed dust temperature, but we cannot rule out the alternative that the AGN powers all the emission in some cases.

", "abstract": "We report the redshift of an unlensed, highly obscured submillimetre galaxy (SMG), HS1700.850.1, the brightest SMG (S_(850\u2009\u03bcm) = 19.1 mJy) detected in the James Clerk Maxwell Telescope/Submillimetre Common-user Bolometer Array-2 (JCMT/SCUBA-2) Baryonic Structure Survey, based on the detection of its ^(12)CO line emission. Using the Institute Radio Astronomie Millimetrique Plateau de Bure Interferometer with 3.6 GHz band width, we serendipitously detect an emission line at 150.6 GHz. From a search over 14.5 GHz in the 3- and 2-mm atmospheric windows, we confirm the identification of this line as ^(12)CO(5\u20134) at z = 2.816, meaning that it does not reside in the z \u223c 2.30 proto-cluster in this field. Measurement of the 870 \u03bcm source size (<0.85 arcsec) from the Sub-Millimetre Array (SMA) confirms a compact emission in a S_(870\u2009\u03bcm) = 14.5 mJy, L_(IR) \u223c 10^(13) L\u2299 component, suggesting an Eddington-limited starburst. We use the double-peaked 12CO line profile measurements along with the SMA size constraints to study the gas dynamics of a HyLIRG, estimating the gas and dynamical masses of HS1700.850.1. While HS1700.850.1 is one of the most extreme galaxies known in the Universe, we find that it occupies a relative void in the Lyman-Break Galaxy distribution in this field. Comparison with other extreme objects at similar epochs (HyLIRG Quasars), and cosmological simulations, suggests such an anti-bias of bright SMGs could be relatively common, with the brightest SMGs rarely occupying the most overdense regions at z = 2\u20134.", "date": "2015-10-11", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "453", "number": "1", "publisher": "Royal Astronomical Society", "pagerange": "951-959", "id_number": "CaltechAUTHORS:20160106-084019133", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20160106-084019133", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Institut national des sciences de l'Univers (INSU)" }, { "agency": "Max-Planck-Gesellschaft" }, { "agency": "Instituto Geogr\u00e1fico Nacional (IGN)" }, { "agency": "Smithsonian Institution" }, { "agency": "Academia Sinica" }, { "agency": "Natural Sciences and Engineering Research Council of Canada (NSERC)" }, { "agency": "Canada Foundation for Innovation" }, { "agency": "Deutsche Forschungsgemeinschaft (DFG)" }, { "agency": "Science and Technology Facilities Council (STFC)" }, { "agency": "Leverhulme Trust" }, { "agency": "European Research Council (ERC)", "grant_number": "DUSTYGAL 321334" }, { "agency": "Royal Society" }, { "agency": "Centre National de la Recherche Scientifique (CNRS)" } ] }, "doi": "10.1093/mnras/stv1618", "primary_object": { "basename": "1503.02195v2.pdf", "url": "https://authors.library.caltech.edu/records/tz4vr-4q521/files/1503.02195v2.pdf" }, "related_objects": [ { "basename": "MNRAS-2015-Chapman-951-9.pdf", "url": "https://authors.library.caltech.edu/records/tz4vr-4q521/files/MNRAS-2015-Chapman-951-9.pdf" } ], "resource_type": "article", "pub_year": "2015", "author_list": "Chapman, S.

", "abstract": "When and how did galaxies form and their metals accumulate? Over the last decade, this has moved from an archeological question to a live investigation: there is now a broad picture of the evolution of galaxies in dark matter halos: their masses, stars, metals and supermassive blackholes. Galaxies have been found and studied in which these formation processes are taking place most vigorously, all the way back in cosmic time to when the intergalactic medium (IGM) was still largely neutral. However, the details of how and why the interstellar medium (ISM) in\ndistant galaxies cools, is processed, recycled and enriched in metals by stars, and fuels active\ngalactic nuclei (AGNs) remain uncertain. In particular, the cooling of gas to fuel star formation,\nand the chemistry and physics of the most intensely active regions is hidden from view at optical\nwavelengths, but can be seen and diagnosed at mid- & far-infrared (IR) wavelengths. Rest-frame\nIR observations are important first to identify the most luminous, interesting and important\ngalaxies, secondly to quantify accurately their total luminosity, and finally to use spectroscopy to\ntrace the conditions in the molecular and atomic gas out of which stars form. In order to map out\nthese processes over the full range of environments and large-scale structures found in the\nuniverse - from the densest clusters of galaxies to the emptiest voids \u2013 we require tools for deep,\nlarge area surveys, of millions of galaxies out to z~5, and for detailed follow-up spectroscopy.\nThe necessary tools can be realized technically.

", "abstract": "We report the blind detection of ^(12)CO emission from a distant red galaxy, HS1700.DRG55. We have used the IRAM Plateau de Bure Interferometer WideX, with its 3.6 GHz of instantaneous dual-polarization bandwidth, to target ^(12)CO(3\u20132) from galaxies lying in the protocluster at z = 2.300 in the field HS1700+64. If indeed this line in DRG55 is ^(12)CO(3\u20132), its detection at 104.9 GHz indicates zCO = 2.296. None of the other eight known z \u223c 2.30 protocluster galaxies lying within the primary beam (PB) are detected in ^(12)CO, although the limits are \u223c2 \u00d7 worse towards the edge of the PB where several lie. The optical/near-IR magnitudes of DRG55 (R_AB > 27, KAB = 22.3) mean that optical spectroscopic redshifts are difficult with 10-m-class telescopes, but near-IR redshifts would be feasible. The 24-\u03bcm-implied star formation rate (210\u2009M_\u2299\u2009yr^\u22121), stellar mass (\u223c10^11\u2009M_\u2299) and ^(12)CO line luminosity (3.6 \u00d7 10^10\u2009K\u2009km\u2009s^\u22121\u2009 pc^2) are comparable to other normal ^(12)CO-detected star-forming galaxies in the literature, although the galaxy is some \u223c2 mag (\u223c6 \u00d7) fainter in the rest-frame UV than ^(12)CO-detected galaxies at z > 2. The detection of DRG55 in ^(12)CO complements three other ^(12)CO detected UV-bright galaxies in this protocluster from previous studies, and suggests that many optically faint galaxies in the protocluster may host substantial molecular gas reservoirs, and a full blind census of ^(12)CO in this overdense environment is warranted.", "date": "2015-05-01", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "449", "number": "1", "publisher": "Royal Astronomical Society", "pagerange": "L68-L72", "id_number": "CaltechAUTHORS:20150518-101259875", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20150518-101259875", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Institut national des sciences de l'Univers (INSU)" }, { "agency": "Centre National de la Recherche Scientifique (CNRS)" }, { "agency": "Max-Planck-Gesellschaft" }, { "agency": "Instituto Geogr\u00e1fico Nacional (IGN)" }, { "agency": "Natural Sciences and Engineering Research Council of Canada (NSERC)" }, { "agency": "Canada Foundation for Innovation" }, { "agency": "Smithsonian Institution" }, { "agency": "Academica Sinica" } ] }, "doi": "10.1093/mnrasl/slv010", "primary_object": { "basename": "1501.02839v2.pdf", "url": "https://authors.library.caltech.edu/records/97yhd-e6s75/files/1501.02839v2.pdf" }, "related_objects": [ { "basename": "MNRAS-2015-Chapman-L68-72.pdf", "url": "https://authors.library.caltech.edu/records/97yhd-e6s75/files/MNRAS-2015-Chapman-L68-72.pdf" } ], "resource_type": "article", "pub_year": "2015", "author_list": "Chapman, S.

", "abstract": "The Wide-field Infrared Survey Explorer mission has unveiled a rare population of high-redshift (z = 1\u20134.6), dusty, hyper-luminous galaxies, with infrared luminosities L_(IR) > 10^(13)L_\u2609, and sometimes exceeding 10^(14)L_\u2609. Previous work has shown that their dust temperatures and overall far-infrared spectral energy distributions (SEDs) are significantly hotter than expected to be powered by star formation. We present here an analysis of the rest-frame optical through mid-infrared SEDs for a large sample of these so-called \"hot, dust-obscured galaxies\" (Hot DOGs). We find that the SEDs of Hot DOGs are generally well modeled by the combination of a luminous, yet obscured active galactic nuclei (AGNs) that dominates the rest-frame emission at \u03bb > 1 \u00b5m and the bolometric luminosity output, and a less luminous host galaxy that is responsible for the bulk of the rest optical/UV emission. Even though the stellar mass of the host galaxies may be as large as 10^(11)\u201310^(12) M_\u2299, the AGN emission, with a range of luminosities comparable to those of the most luminous QSOs known, require that either Hot DOGs have black hole masses significantly in excess of the local relations, or that they radiate significantly above the Eddington limit, at a level at least 10 times more efficiently than z ~ 2 QSOs. We show that, while rare, the number density of Hot DOGs is comparable to that of equally luminous but unobscured (i.e., Type 1) QSOs. This may be at odds with the trend suggested at lower luminosities for the fraction of obscured AGNs to decrease with increasing luminosity. That trend may, instead, reverse at higher luminosities. Alternatively, Hot DOGs may not be the torus-obscured counterparts of the known optically selected, largely unobscured, hyper-luminous QSOs, and may represent a new component of the galaxy evolution paradigm. Finally, we discuss the environments of Hot DOGs and statistically show that these objects are in regions as dense as those of known high-redshift proto-clusters.", "date": "2015-05-01", "date_type": "published", "publication": "Astrophysical Journal", "volume": "804", "number": "1", "publisher": "American Astronomical Society", "pagerange": "Art.

", "abstract": "We present JCMT SCUBA-2 850 \u03bcm submillimetre (submm) observations of 30 mid-infrared (mid-IR) luminous active galactic nuclei (AGNs), detected jointly by the Wide-field Infrared Survey Explorer (WISE) all-sky IR survey and the NVSS/FIRST radio survey. These rare sources are selected by their extremely red mid-IR spectral energy distributions (SEDs) and compact radio counterparts. Further investigations show that they are highly obscured, have abundant warm AGN-heated dust and are thought to be experiencing intense AGN feedback. These galaxies appear to be consistent with a later AGN-dominated phase of merging galaxies, while hot, dust-obscured galaxies are an earlier starburst-dominated phase. When comparing the number of submm galaxies detected serendipitously in the surrounding 1.5 arcmin to those in blank-field submm surveys, there is a very significant overdensity, of order 5, but no sign of radial clustering centred at our primary objects. The WISE/radio-selected AGN thus reside in 10-Mpc-scale overdense environments that could be forming in pre-viralized clusters of galaxies. WISE/radio-selected AGNs appear to be the strongest signposts of high-density regions of active, luminous and dusty galaxies. SCUBA-2 850 \u03bcm observations indicate that their submm fluxes are low compared to many popular AGN SED templates, hence the WISE/radio-selected AGNs have either less cold and/or more warm dust emission than normally assumed for typical AGN. Most of the targets are not detected, only four targets are detected at SCUBA-2 850 \u03bcm, and have total IR luminosities \u226510^(13) L\u2299, if their redshifts are consistent with the subset of the 10 SCUBA-2 undetected targets with known redshifts, z \u223c 0.44\u20132.86.", "date": "2015-04-21", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "448", "number": "4", "publisher": "Royal Astronomical Society", "pagerange": "3325-3338", "id_number": "CaltechAUTHORS:20150424-145449611", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20150424-145449611", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "University of Leicester" }, { "agency": "NASA" }, { "agency": "Comisi\u00f3n Nacional de Investigaci\u00f3n Cient\u00edfica y Tecnol\u00f3gica (CONICYT)", "grant_number": "32120009" } ] }, "local_group": { "items": [ { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" } ] }, "doi": "10.1093/mnras/stv214", "primary_object": { "basename": "1503.02561v1.pdf", "url": "https://authors.library.caltech.edu/records/m1dtb-k6x32/files/1503.02561v1.pdf" }, "related_objects": [ { "basename": "MNRAS-2015-Jones-3325-38.pdf", "url": "https://authors.library.caltech.edu/records/m1dtb-k6x32/files/MNRAS-2015-Jones-3325-38.pdf" } ], "resource_type": "article", "pub_year": "2015", "author_list": "Jones, Suzy F.; Blain, Andrew W.; et el." }, { "id": "https://authors.library.caltech.eduhttps://authors.library.caltech.edu/records/62afg-gk992", "eprint_id": 69914, "eprint_status": "archive", "datestamp": "2023-08-20 03:11:59", "lastmod": "2023-10-20 20:46:33", "type": "article", "metadata_visibility": "show", "creators": { "items": [ { "id": "Stern-D", "name": { "family": "Stern", "given": "Daniel" }, "orcid": "0000-0003-2686-9241" }, { "id": "Lansbury-G-B", "name": { "family": "Lansbury", "given": "G.

", "abstract": "We report on a NuSTAR and XMM-Newton program that has observed a sample of three extremely luminous, heavily obscured WISE-selected active galactic nuclei (AGNs) at z ~ 2 across a broad X-ray band (0.1 - 79 keV). The parent sample, selected to be faint or undetected in the WISE 3.4 \u03bcm (W1) and 4.6 \u03bcm (W2) bands but bright at 12 \u03bcm (W3) and 22 \u03bcm (W4), are extremely rare, with only ~1000 so-called \"W1W2-dropouts\" across the extragalactic sky. Optical spectroscopy reveals typical redshifts of z ~ 2 for this population, implying rest-frame mid-IR luminosities of \u03bdL \u03bd(6 \u03bcm) ~ 6 \u00d7 1046 erg s^-1 and bolometric luminosities that can exceed L bol ~ 1014 L_\u2299. The corresponding intrinsic, unobscured hard X-ray luminosities are L(2-10 keV) ~ 4 \u00d7 1045 erg s-1 for typical quasar templates. These are among the most AGNs known, though the optical spectra rarely show evidence of a broad-line region and the selection criteria imply heavy obscuration even at rest-frame 1.5 \u03bcm. We designed our X-ray observations to obtain robust detections for gas column densities N H <= 1024 cm-2. In fact, the sources prove to be fainter than these predictions. Two of the sources were observed by both NuSTAR and XMM-Newton, with neither being detected by NuSTAR (f 3-24 keV <~ 10-13 erg cm^(-2)s^(-1), and one being faintly detected by XMM-Newton (f 0.5-10 keV ~ 5 \u00d7 10-15 erg cm-2 s-1). A third source was observed only with XMM-Newton, yielding a faint detection (f 0.5-10 keV ~ 7 \u00d7 10-15 erg cm-2 s-1). The X-ray data imply these sources are either X-ray weak, or are heavily obscured by column densities N H >~ 1024 cm-2. The combined X-ray and mid-IR analysis seems to favor this second possibility, implying the sources are extremely obscured, consistent with Compton-thick, luminous quasars. The discovery of a significant population of heavily obscured, extremely luminous AGNs would not conform to the standard paradigm of a receding torus, in which more luminous quasars are less likely to be obscured, and instead suggests that an additional source of obscuration is present in these extreme sources.", "date": "2014-10", "date_type": "published", "publication": "Astrophysical Journal", "volume": "79", "number": "2", "publisher": "American Astronomical Society", "pagerange": "Art No.102", "id_number": "CaltechAUTHORS:20160824-144504856", "issn": "0004-637X", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20160824-144504856", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "NNG08FD60C" }, { "agency": "Science and Technology Facilities Council (STFC)", "grant_number": "ST/K501979/1" }, { "agency": "Science and Technology Facilities Council (STFC)", "grant_number": "ST/J003697/1" }, { "agency": "Leverhulme Trust" }, { "agency": "Comisi\u00f3n Nacional de Investigaci\u00f3n Cient\u00edfica y Tecnol\u00f3gica (CONICYT)", "grant_number": "32120009" }, { "agency": "Basal-CATA", "grant_number": "PFB-06/2007" }, { "agency": "Fondo Nacional de Desarrollo Cient\u00edfico y Tecnol\u00f3gico (FONDECYT)", "grant_number": "1141218" }, { "agency": "Comisi\u00f3n Nacional de Investigaci\u00f3n Cient\u00edfica y Tecnol\u00f3gica (CONICYT)", "grant_number": "EMBIGGEN Anillo ACT1101" }, { "agency": "Iniciativa Cient\u00edfica Milenio (ICM) del Ministerio de Econom\u00eda", "grant_number": "IC120009" }, { "agency": "Agenzia Spaziale Italiana (ASI)", "grant_number": "I/37/012/0-011/13" }, { "agency": "NASA", "grant_number": "NNX12AE38G" }, { "agency": "NSF", "grant_number": "1211096" }, { "agency": "Swiss Science Foundation (SNSF)", "grant_number": "PP00P2138979/1" }, { "agency": "Istituto Nazionale di Astrofisica (INAF)" } ] }, "other_numbering_system": { "items": [ { "id": "2014-28", "name": "Space Radiation Laboratory" } ] }, "local_group": { "items": [ { "id": "Space-Radiation-Laboratory" }, { "id": "NuSTAR" }, { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" } ] }, "doi": "10.1088/0004-637X/794/2/102", "primary_object": { "basename": "2014-28.pdf", "url": "https://authors.library.caltech.edu/records/62afg-gk992/files/2014-28.pdf" }, "resource_type": "article", "pub_year": "2014", "author_list": "Stern, Daniel; Lansbury, G.

", "abstract": "The Wide-field Infrared Survey Explorer (WISE) has discovered an extraordinary population of hyper-luminous dusty galaxies that are faint in the two bluer passbands (3.4 \u03bcm and 4.6 \u03bcm) but are bright in the two redder passbands of WISE (12 \u03bcm and 22 \u03bcm). We report on initial follow-up observations of three of these hot, dust-obscured galaxies, or Hot DOGs, using the Combined Array for Research in Millimeter-wave Astronomy and the Submillimeter Array interferometer arrays at submillimeter/millimeter wavelengths. We report continuum detections at ~1.3 mm of two sources (WISE J014946.17+235014.5 and WISE J223810.20+265319.7, hereafter W0149+2350 and W2238+2653, respectively), and upper limits to CO line emission at 3 mm in the observed frame for two sources (W0149+2350 and WISE J181417.29+341224.8, hereafter W1814+3412). The 1.3 mm continuum images have a resolution of 1\"-2\" and are consistent with single point sources. We estimate the masses of cold dust are 2.0 \u00d7 10^8 M_\u2609 for W0149+2350 and 3.9 \u00d7 10^8 M_\u2609 for W2238+2653, comparable to cold dust masses of luminous quasars. We obtain 2\u03c3 upper limits to the molecular gas masses traced by CO, which are 3.3 \u00d7 10^(10) M_\u2609 and 2.3 \u00d7 10^(10) M_\u2609 for W0149+2350 and W1814+3412, respectively. We also present high-resolution, near-IR imaging with the WFC3 on the Hubble Space Telescope for W0149+2653 and with NIRC2 on Keck for W2238+2653. The near-IR images show morphological structure dominated by a single, centrally condensed source with effective radius less than 4 kpc.

", "abstract": "We present SCUBA-2 (Submillimetre Common-User Bolometer Array) 850\u2009\u03bcm submillimetre (submm) observations of the fields of 10 dusty, luminous galaxies at z \u223c 1.7\u20134.6, detected at 12 and/or 22\u2009\u03bcm by the Wide-field Infrared Survey Explorer (WISE) all-sky survey, but faint or undetected at 3.4 and 4.6\u2009\u03bcm; dubbed hot, dust-obscured galaxies (Hot DOGs). The six detected targets all have total infrared luminosities greater than 10^(13)\u2009L_\u2299, with one greater than 10^(14)\u2009L_\u2299. Their spectral energy distributions (SEDs) are very blue from mid-infrared to submm wavelengths and not well fitted by standard active galactic nuclei (AGN) SED templates, without adding extra dust extinction to fit the WISE 3.4 and 4.6\u2009\u03bcm data. The SCUBA-2 850\u2009\u03bcm observations confirm that the Hot DOGs have less cold and/or more warm dust emission than standard AGN templates, and limit an underlying extended spiral or ULIRG-type galaxy to contribute less than about 2 or 55\u2009per\u2009cent of the typical total Hot DOG IR luminosity, respectively. The two most distant and luminous targets have similar observed submm to mid-infrared ratios to the rest, and thus appear to have even hotter SEDs. The number of serendipitous submm galaxies detected in the 1.5-arcmin-radius SCUBA-2 850\u2009\u03bcm maps indicates there is a significant overdensity of serendipitous sources around Hot DOGs. These submm observations confirm that the WISE-selected ultraluminous galaxies have very blue mid-infrared to submm SEDs, suggesting that they contain very powerful AGN, and are apparently located in unusual arcmin-scale overdensities of very luminous dusty galaxies.", "date": "2014-09-01", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "443", "number": "1", "publisher": "Royal Astronomical Society", "pagerange": "146-157", "id_number": "CaltechAUTHORS:20140904-152428097", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20140904-152428097", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "University of Leicester" }, { "agency": "Gemini-CONICYT", "grant_number": "32120009" }, { "agency": "NASA/JPL/Caltech" }, { "agency": "Canada Foundation for Innovation" } ] }, "local_group": { "items": [ { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" } ] }, "doi": "10.1093/mnras/stu1157", "primary_object": { "basename": "MNRAS-2014-Jones-146-57.pdf", "url": "https://authors.library.caltech.edu/records/cmqtc-pgz41/files/MNRAS-2014-Jones-146-57.pdf" }, "resource_type": "article", "pub_year": "2014", "author_list": "Jones, Suzy F.; Blain, Andrew W.; et el." }, { "id": "https://authors.library.caltech.eduhttps://authors.library.caltech.edu/records/bvb6j-ypz92", "eprint_id": 43436, "eprint_status": "archive", "datestamp": "2023-08-22 11:05:46", "lastmod": "2023-10-25 23:32:46", "type": "article", "metadata_visibility": "show", "creators": { "items": [ { "id": "Tsai-Chao-Wei", "name": { "family": "Tsai", "given": "Chao-Wei" }, "orcid": "0000-0002-9390-9672" }, { "id": "Jarrett-T-H", "name": { "family": "Jarrett", "given": "T.

This source exhibits an FR-I and FR-II hybrid morphology, characterized by a bright core, jet, and Doppler-boosted lobe structures in Australian Telescope Compact Array continuum maps at 1.5, 5.6, and 9 GHz. Unlike most FR-II objects, W2332\u20135056 is hosted by a disk-like galaxy. The core has a projected 5'' linear radio feature that is perpendicular to the curved primary jet, hinting at unusual and complex activity within the inner 25 kpc. The multi-epoch, optical-near-IR photometric measurements indicate significant variability over a 3-20 yr baseline from the AGN component. Gemini South optical data show unusual double-peaked emission-line features: the centroids of the broad-lined components of H\u03b1 and H\u03b2 are blueshifted with respect to the narrow lines and host galaxy by ~3800 km s^(\u20131).

", "abstract": "We present WISE All-Sky mid-infrared (IR) survey detections of 55% (17/31) of the known QSOs at z > 6 from a range of surveys: the SDSS, the CFHT-LS, FIRST, Spitzer, and UKIDSS. The WISE catalog thus provides a substantial increase in the quantity of IR data available for these sources: 17 are detected in the WISE W1 (3.4 \u03bcm) band, 16 in W2 (4.6 \u03bcm), 3 in W3 (12 \u03bcm), and 0 in W4 (22 \u03bcm). This is particularly important with Spitzer in its warm-mission phase and no faint follow-up capability at wavelengths longward of 5 \u03bcm until the launch of James Webb Space Telescope (JWST). WISE thus provides a useful tool for understanding QSOs found in forthcoming large-area optical/IR sky surveys using PanSTARRS, SkyMapper, VISTA, DES, and LSST. The rest-UV properties of the WISE-detected and the WISE-non-detected samples differ: the detections have brighter i/z-band magnitudes and redder rest-UV colors. This suggests that a more aggressive hunt for very high redshift QSOs by combining WISE W1 and W2 data with red, observed optical colors could be effective at least for a subset of dusty candidate QSOs. Stacking the WISE images of the WISE-non-detected QSOs indicates that they are, on average, significantly fainter than the WISE-detected examples, and are thus not narrowly missing detection in the WISE catalog. The WISE catalog detection of three of our sample in the W3 band indicates that their mid-IR flux can be detected individually, although there is no stacked W3 detection of sources detected in W1 but not W3. Stacking analyses of WISE data for large active galactic nucleus samples will be a useful tool, and high-redshift QSOs of all types will be easy targets for JWST.", "date": "2013-12-01", "date_type": "published", "publication": "Astrophysical Journal", "volume": "778", "number": "2", "publisher": "American Astronomical Society", "pagerange": "Art.

", "abstract": "In the local universe, 10% of massive elliptical galaxies are observed to exhibit a peculiar property: a substantial excess of ultraviolet emission than what is expected from their old, red stellar populations. Several origins for this ultraviolet excess (UVX) have been proposed including a population of hot young stars and a population of old, blue horizontal branch or extended horizontal branch (BHB or EHB) stars that have undergone substantial mass loss from their outer atmospheres. We explore the radial distribution of UVX in a selection of 49 nearby E/S0-type galaxies by measuring their extended photometry in the UV through mid-infrared (mid-IR) with the Galaxy Evolution Explorer (GALEX), the Sloan Digital Sky Survey, and the Wide-field Infrared Survey Explorer (WISE). We compare UV/optical and UV/mid-IR colors with the Flexible Stellar Population Synthesis models, which allow for the inclusion of EHB stars. We find that combined WISE mid-IR and GALEX UV colors are more effective in distinguishing models than optical colors, and that the UV/mid-IR combination is sensitive to the EHB fraction. There are strong color gradients, with the outer radii bluer than the inner half-light radii by ~1 mag. This color difference is easily accounted for with an increase in the BHB fraction of 0.25 with radius. We estimated that the average ages for the inner and outer radii are 7.0 \u00b1 0.3 Gyr, and 6.2 \u00b1 0.2 Gyr, respectively, with the implication that the outer regions are likely to have formed ~1 Gyr after the inner regions. Additionally, we find that metallicity gradients are likely not a significant factor in the color difference. The separation of color between the inner and outer regions, which agrees with a specific stellar population difference (e.g., higher EHB populations), and the ~0.5\u20132 Gyr age difference suggests multi-stage formation. Our results are best explained by inside-out formation: rapid star formation within the core at early epochs (>4 Gyr ago) and at least one later stage starburst event coinciding with z ~ 1.", "date": "2013-10", "date_type": "published", "publication": "Astronomical Journal", "volume": "146", "number": "4", "publisher": "American Astronomical Society", "pagerange": "Art.

", "abstract": "Stern et al. presented a study of Wide-field Infrared Survey Explorer (WISE) selection of active galactic nuclei (AGNs) in the 2 deg^2 COSMOS field, finding that a simple criterion W1-W2 \u2265 0.8 provides a highly reliable and complete AGN sample for W2 < 15.05, where the W1 and W2 passbands are centered at 3.4 \u03bcm and 4.6 \u03bcm, respectively. Here we extend this study using the larger 9 deg^2 NOAO Deep Wide-Field Survey Bo\u00f6tes field which also has considerably deeper WISE observations than the COSMOS field, and find that this simple color cut significantly loses reliability at fainter fluxes. We define a modified selection criterion combining the W1\u2013W2 color and the W2 magnitude to provide highly reliable or highly complete AGN samples for fainter WISE sources. In particular, we define a color-magnitude cut that finds 130 \u00b1 4 deg^(\u20132) AGN candidates for W2 < 17.11 with 90% reliability. Using the extensive UV through mid-IR broadband photometry available in this field, we study the spectral energy distributions of WISE AGN candidates. We find that, as expected, the WISE AGN selection can identify highly obscured AGNs, but that it is biased toward objects where the AGN dominates the bolometric luminosity output. We study the distribution of reddening in the AGN sample and discuss a formalism to account for sample incompleteness based on the step-wise maximum-likelihood method of Efstathiou et al. The resulting dust obscuration distributions depend strongly on AGN luminosity, consistent with the trend expected for a receding torus. At L_AGN ~ 3 \u00d7 10^(44) erg s^\u20131, 29% \u00b1 7% of AGNs are observed as Type 1, while at ~4 \u00d7 10^(45) erg s^(\u20131) the fraction is 64% \u00b1 13%.

", "abstract": "By combining data from the NASA Wide-field Infrared Survey Explorer (WISE) mission with optical spectroscopy from the W. M. Keck telescope, we discover a mid-IR color criterion that yields a 78% success rate in identifying rare, typically radio-quiet, 1.6 \u227e z \u227e 4.6 dusty Ly\u03b1 emitters (LAEs). Of these, at least 37% have emission extended on scales of 30-100 kpc and are considered Ly\u03b1 \"blobs\" (LABs). The objects have a surface density of only ~0.1 deg^(\u20132), making them rare enough that they have been largely missed in deep, small area surveys. We measured spectroscopic redshifts for 92 of these galaxies, and find that the LAEs (LABs) have a median redshift of 2.3 (2.5). The WISE photometry coupled with data from Herschel (Herschel is an ESA space observatory with science instruments provided by European-led Principal Investigator consortia and with important participation from NASA) reveals that these galaxies are in the Hyper Luminous IR galaxy regime (L IR \u2273 10^(13)-10^(14) L_\u2609) and have warm colors. They are typically more luminous and warmer than other dusty, z ~ 2 populations such as submillimeter-selected galaxies and dust-obscured galaxies. These traits are commonly associated with the dust being illuminated by intense active galactic nucleus activity. We hypothesize that the combination of spatially extended Ly\u03b1, large amounts of warm IR-luminous dust, and rarity (implying a short-lived phase) can be explained if the galaxies are undergoing brief, intense \"feedback\" transforming them from an extreme dusty starburst/QSO into a mature galaxy.", "date": "2013-06-01", "date_type": "published", "publication": "Astrophysical Journal", "volume": "769", "number": "2", "publisher": "American Astronomical Society", "pagerange": "Art.

", "abstract": "We present the first integral-field spectroscopic observations of high-redshift submillimeter-selected galaxies (SMGs) using Laser-Guide Star Adaptive Optics. We target H\u03b1 emission of three SMGs at redshifts z ~ 1.4-2.4 with the OH-Suppressing Infrared Imaging Spectrograph on Keck. The spatially resolved spectroscopy of these galaxies reveals unresolved broad-H\u03b1 line regions (FWHM >1000 km s^(\u20131)) likely associated with an active galactic nucleus (AGN) and regions of diffuse star formation traced by narrow-line H\u03b1 emission (FWHM \u227e 500 km s^(\u20131)) dominated by multiple H\u03b1-bright stellar clumps, each contributing 1%-30% of the total clump-integrated H\u03b1 emission. We find that these SMGs host high star formation rate surface densities, similar to local extreme sources, such as circumnuclear starbursts and luminous infrared galaxies. However, in contrast to these local environments, SMGs appear to be undergoing such intense activity on significantly larger spatial scales as revealed by extended H\u03b1 emission over 4-16 kpc. H\u03b1 kinematics show no evidence of ordered global motion as would be found in a disk, but rather large velocity offsets (~few \u00d7 100 km s^(\u20131)) between the distinct stellar clumps. Together with the asymmetric distribution of the stellar clumps around the AGN in these objects, it is unlikely that we are unveiling a clumpy disk structure as has been suggested in other high-redshift populations of star-forming galaxies. The SMG clumps in this sample may correspond to remnants of originally independent gas-rich systems that are in the process of merging, hence triggering the ultraluminous SMG phase.", "date": "2013-04-20", "date_type": "published", "publication": "Astrophysical Journal", "volume": "767", "number": "2", "publisher": "American Astronomical Society", "pagerange": "Art.

", "abstract": "The Wide-field Infrared Survey Explorer (WISE) has completed its all-sky survey in four channels at 3.4-22 \u03bcm, detecting hundreds of millions of objects. We merge the WISE mid-infrared data with optical data from the Sloan Digital Sky Survey (SDSS) and provide a phenomenological characterization of WISE extragalactic sources. WISE is most sensitive at 3.4 \u03bcm (W1) and least sensitive at 22 \u03bcm (W4). The W1 band probes massive early-type galaxies out to z \u2273 1. This is more distant than SDSS identified early-type galaxies, consistent with the fact that 28% of 3.4 \u03bcm sources have faint or no r-band counterparts (r > 22.2). In contrast, 92%-95% of 12 \u03bcm and 22 \u03bcm sources have SDSS optical counterparts with r \u2264 22.2. WISE 3.4 \u03bcm detects 89.8% of the entire SDSS QSO catalog at S/N_(W1) >7\u03c3, but only 18.9% at 22 \u03bcm with S/N_(W4) > 5\u03c3. We show that WISE colors alone are effective in isolating stars (or local early-type galaxies), star-forming galaxies, and strong active galactic nuclei (AGNs)/QSOs at z \u227e 3. We highlight three major applications of WISE colors: (1) Selection of strong AGNs/QSOs at z \u2264 3 using W1 \u2013 W2 > 0.8 and W2 < 15.2 criteria, producing a better census of this population. The surface density of these strong AGN/QSO candidates is 67.5 \u00b1 0.14 deg^(\u20132). (2) Selection of dust-obscured, type-2 AGN/QSO candidates. We show that WISE W1 \u2013 W2 > 0.8, W2 < 15.2 combined with r \u2013 W2 > 6 (Vega) colors can be used to identify type-2 AGN candidates. The fraction of these type-2 AGN candidates is one-third of all WISE color-selected AGNs. (3) Selection of ultraluminous infrared galaxies (ULIRGs) at z ~ 2 with extremely red colors, r \u2013 W4 > 14 or well-detected 22 \u03bcm sources lacking detections in the 3.4 and 4.6 \u03bcm bands. The surface density of z ~ 2 ULIRG candidates selected with r \u2013 W4 > 14 is 0.9 \u00b1 0.07 deg^(\u20132) at S/N_(W4) \u2265 5 (the corresponding, lowest flux density of 2.5 mJy), which is consistent with that inferred from smaller area Spitzer surveys. Optical spectroscopy of a small number of these high-redshift ULIRG candidates confirms our selection, and reveals a possible trend that optically fainter or r \u2013 W4 redder candidates are at higher redshifts.", "date": "2013-03", "date_type": "published", "publication": "Astronomical Journal", "volume": "145", "number": "3", "publisher": "American Astronomical Society", "pagerange": "Art.

", "abstract": "The Wide-field Infrared Survey Explorer (WISE) mapped the entire sky at mid-infrared wavelengths 3.4 \u03bcm, 4.6 \u03bcm, 12 \u03bcm, and 22 \u03bcm. The mission was primarily designed to extract point sources, leaving resolved and extended sources, for the most part, unexplored. Accordingly, we have begun a dedicated WISE Enhanced Resolution Galaxy Atlas (WERGA) project to fully characterize large, nearby galaxies and produce a legacy image atlas and source catalog. Here we demonstrate the first results of the WERGA project for a sample of 17 galaxies, chosen to be of large angular size, diverse morphology, and covering a range in color, stellar mass, and star formation. It includes many well-studied galaxies, such as M 51, M 81, M 87, M 83, M 101, and IC 342. Photometry and surface brightness decomposition is carried out after special super-resolution processing, achieving spatial resolutions similar to that of Spitzer Infrared Array Camera. The enhanced resolution method is summarized in the first paper of this two-part series. In this second work, we present WISE, Spitzer, and Galaxy Evolution Explorer (GALEX) photometric and characterization measurements for the sample galaxies, combining the measurements to study the global properties. We derive star formation rates using the polycyclic aromatic hydrocarbon sensitive 12 \u03bcm (W3) fluxes, warm-dust sensitive 22 \u03bcm (W4) fluxes, and young massive-star sensitive ultraviolet (UV) fluxes. Stellar masses are estimated using the 3.4 \u03bcm (W1) and 4.6 \u03bcm (W2) measurements that trace the dominant stellar mass content. We highlight and showcase the detailed results of M 83, comparing the WISE/Spitzer results with the Australia Telescope Compact Array H I gas distribution and GALEX UV emission, tracing the evolution from gas to stars. In addition to the enhanced images, WISE's all-sky coverage provides a tremendous advantage over Spitzer for building a complete nearby galaxy catalog, tracing both stellar mass and star formation histories. We discuss the construction of a complete mid-infrared catalog of galaxies and its complementary role of studying the assembly and evolution of galaxies in the local universe.", "date": "2013-01", "date_type": "published", "publication": "Astronomical Journal", "volume": "145", "number": "1", "publisher": "American Astronomical Society", "pagerange": "Art.

", "abstract": "Using far-infrared imaging from the \"Herschel Lensing Survey,\" we derive dust properties of spectroscopically confirmed cluster member galaxies within two massive systems at z ~ 0.3: the merging Bullet Cluster and the more relaxed MS2137.3-2353. Most star-forming cluster sources (~90%) have characteristic dust temperatures similar to local field galaxies of comparable infrared (IR) luminosity (T_dust ~ 30 K). Several sub-luminous infrared galaxy (LIRG; L_IR < 10^(11) L_\u2609) Bullet Cluster members are much warmer (T_dust > 37 K) with far-infrared spectral energy distribution (SED) shapes resembling LIRG-type local templates. X-ray and mid-infrared data suggest that obscured active galactic nuclei do not contribute significantly to the infrared flux of these \"warm dust\" galaxies. Sources of comparable IR luminosity and dust temperature are not observed in the relaxed cluster MS2137, although the significance is too low to speculate on an origin involving recent cluster merging. \"Warm dust\" galaxies are, however, statistically rarer in field samples (>3\u03c3), indicating that the responsible mechanism may relate to the dense environment. The spatial distribution of these sources is similar to the whole far-infrared bright population, i.e., preferentially located in the cluster periphery, although the galaxy hosts tend toward lower stellar masses (M_* < 10^10 M_\u2609). We propose dust stripping and heating processes which could be responsible for the unusually warm characteristic dust temperatures. A normal star-forming galaxy would need 30%-50% of its dust removed (preferentially stripped from the outer reaches, where dust is typically cooler) to recover an SED similar to a \"warm dust\" galaxy. These progenitors would not require a higher IR luminosity or dust mass than the currently observed normal star-forming population.", "date": "2012-09-10", "date_type": "published", "publication": "Astrophysical Journal", "volume": "756", "number": "2", "publisher": "American Astronomical Society", "pagerange": "Art.

", "abstract": "We have used the Caltech Submillimeter Observatory (CSO) to follow-up a sample of Wide-field Infrared Survey Explorer (WISE) selected, hyperluminous galaxies, the so-called W1W2-dropout galaxies. This is a rare (∼1000 all-sky) population of galaxies at high redshift (peaks at z = 2–3), which are faint or undetected by WISE at 3.4 and 4.6 μm, yet are clearly detected at 12 and 22 μm. The optical spectra of most of these galaxies show significant active galactic nucleus activity. We observed 14 high-redshift (z > 1.7) W1W2-dropout galaxies with SHARC-II at 350–850 μm, with nine detections, and observed 18 with Bolocam at 1.1 mm, with five detections. Warm Spitzer follow-up of 25 targets at 3.6 and 4.5 μm, as well as optical spectra of 12 targets, are also presented in the paper. Combining WISE data with observations from warm Spitzer and CSO, we constructed their mid-IR to millimeter spectral energy distributions (SEDs). These SEDs have a consistent shape, showing significantly higher mid-IR to submillimeter ratios than other galaxy templates, suggesting a hotter dust temperature. We estimate their dust temperatures to be 60–120 K using a single-temperature model. Their infrared luminosities are well over 1013 L\u2609. These SEDs are not well fitted with existing galaxy templates, suggesting they are a new population with very high luminosity and hot dust. They are likely among the most luminous galaxies in the universe. We argue that they are extreme cases of luminous, hot dust-obscured galaxies (DOGs), possibly representing a short evolutionary phase during galaxy merging and evolution. A better understanding of their long-wavelength properties needs ALMA as well as Herschel data.

", "abstract": "We report the discovery by the Wide-field Infrared Survey Explorer (WISE) of the z = 2.452 source WISE J181417.29+341224.9, the first hyperluminous source found in the WISE survey. WISE 1814+3412 is also the prototype for an all-sky sample of ∼1000 extremely luminous \"W1W2-dropouts\" (sources faint or undetected by WISE at 3.4 and 4.6 μm and well detected at 12 or 22 μm). The WISE data and a 350 μm detection give a minimum bolometric luminosity of 3.7 × 1013 L\u2609, with ∼1014 L\u2609 plausible. Follow-up images reveal four nearby sources: a QSO and two Lyman break galaxies (LBGs) at z = 2.45, and an M dwarf star. The brighter LBG dominates the bolometric emission. Gravitational lensing is unlikely given the source locations and their different spectra and colors. The dominant LBG spectrum indicates a star formation rate ∼300 M\u2609 yr−1, accounting for \u2272 10% of the bolometric luminosity. Strong 22 μm emission relative to 350 μm implies that warm dust contributes significantly to the luminosity, while cooler dust normally associated with starbursts is constrained by an upper limit at 1.1 mm. Radio emission is ∼10 times above the far-infrared/radio correlation, indicating an active galactic nucleus (AGN) is present. An obscured AGN combined with starburst and evolved stellar components can account for the observations. If the black hole mass follows the local MBH–bulge mass relation, the implied Eddington ratio is \u2273 4. WISE 1814+3412 may be a heavily obscured object where the peak AGN activity occurred prior to the peak era of star formation.

", "abstract": "The Herschel Multi-tiered Extragalactic Survey (HerMES) is a legacy programme designed to map a set of nested fields totalling \u223c380\u2009deg^2. Fields range in size from 0.01 to \u223c20\u2009deg^2, using the Herschel-Spectral and Photometric Imaging Receiver (SPIRE) (at 250, 350 and 500\u2009\u03bcm) and the Herschel-Photodetector Array Camera and Spectrometer (PACS) (at 100 and 160\u2009\u03bcm), with an additional wider component of 270\u2009deg^2 with SPIRE alone. These bands cover the peak of the redshifted thermal spectral energy distribution from interstellar dust and thus capture the reprocessed optical and ultraviolet radiation from star formation that has been absorbed by dust, and are critical for forming a complete multiwavelength understanding of galaxy formation and evolution. \n\nThe survey will detect of the order of 100\u2009000 galaxies at 5\u03c3 in some of the best-studied fields in the sky. Additionally, HerMES is closely coordinated with the PACS Evolutionary Probe survey. Making maximum use of the full spectrum of ancillary data, from radio to X-ray wavelengths, it is designed to facilitate redshift determination, rapidly identify unusual objects and understand the relationships between thermal emission from dust and other processes. Scientific questions HerMES will be used to answer include the total infrared emission of galaxies, the evolution of the luminosity function, the clustering properties of dusty galaxies and the properties of populations of galaxies which lie below the confusion limit through lensing and statistical techniques. \n\nThis paper defines the survey observations and data products, outlines the primary scientific goals of the HerMES team, and reviews some of the early results.", "date": "2012-08-11", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "424", "number": "3", "publisher": "Royal Astronomical Society", "pagerange": "1614-1635", "id_number": "CaltechAUTHORS:20120927-094554573", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20120927-094554573", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Science and Technology Facilities Council (STFC)", "grant_number": "ST/F002858/1" }, { "agency": "Science and Technology Facilities Council (STFC)", "grant_number": "ST/I000976/1" }, { "agency": "Herschel Science Ground Segment Consortium" }, { "agency": "NASA Herschel Science Center" }, { "agency": "HIFI" }, { "agency": "PACS" }, { "agency": "SPIRE" }, { "agency": "European Space Agency (ESA)" } ] }, "local_group": { "items": [ { "id": "TAPIR" }, { "id": "COSMOS" }, { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" } ] }, "doi": "10.1111/j.1365-2966.2012.20912.x", "primary_object": { "basename": "1203.2562.pdf", "url": "https://authors.library.caltech.edu/records/vdjgt-62z57/files/1203.2562.pdf" }, "related_objects": [ { "basename": "mnr20912.pdf", "url": "https://authors.library.caltech.edu/records/vdjgt-62z57/files/mnr20912.pdf" } ], "resource_type": "article", "pub_year": "2012", "author_list": "Oliver, S.

", "abstract": "The Wide-field Infrared Survey Explorer (WISE) is an extremely capable and efficient black hole finder. We present a simple mid-infrared color criterion, W1 \u2013 W2 \u2265 0.8 (i.e., [3.4]\u2013[4.6] \u22650.8, Vega), which identifies 61.9 \u00b1 5.4 active galactic nucleus (AGN) candidates per deg^2 to a depth of W2 ~ 15.0. This implies a much larger census of luminous AGNs than found by typical wide-area surveys, attributable to the fact that mid-infrared selection identifies both unobscured (type 1) and obscured (type 2) AGNs. Optical and soft X-ray surveys alone are highly biased toward only unobscured AGNs, while this simple WISE selection likely identifies even heavily obscured, Compton-thick AGNs. Using deep, public data in the COSMOS field, we explore the properties of WISE-selected AGN candidates. At the mid-infrared depth considered, 160 \u03bcJy at 4.6 \u03bcm, this simple criterion identifies 78% of Spitzer mid-infrared AGN candidates according to the criteria of Stern et al. and the reliability is 95%.

We find that the function that best describes this relation is a three-dimensional linear fit in the space of log (albedo)-log (polarization slope)-log (minimum polarization). When projected to two dimensions, the parameters of the fit are consistent with those found in previous work. We also define p^* as the quantity of maximal polarization variation when compared with the albedo and present the best-fitting albedo-p^* relation. Some asteroid taxonomic types stand out in this three-dimensional space, notably the E, B, and M Tholen types, while others cluster in clumps coincident with the S- and C-complex bodies. We note that both low albedo and small (D < 30 km) asteroids are underrepresented in the polarimetric sample, and we encourage future polarimetric surveys to focus on these bodies.", "date": "2012-04", "date_type": "published", "publication": "Astrophysical Journal", "volume": "749", "number": "2", "publisher": "American Astronomical Society", "pagerange": "Art.

From a sample of 63 previously identified mm sources with reliable radio identifications in the Great Observatories Origins Deep Survey North and Lockman Hole North fields, 46 (73 per cent) are found to have detections in at least one SPIRE band. We explore the observed submm/mm colour evolution with redshift, finding that the colours of mm sources are adequately described by a modified blackbody with constant optical depth \u03c4= (\u03bd/nu_0)^\u03b2, where \u03b2=+1.8 and \u03bd_0=c/100 \u03bcm. We find a tight correlation between dust temperature and IR luminosity. Using a single model of the dust temperature and IR luminosity relation, we derive photometric redshift estimates for the 46 SPIRE-detected mm sources. Testing against the 22 sources with known spectroscopic or good quality optical/near-IR photometric redshifts, we find submm/mm photometric redshifts offer a redshift accuracy of |\u0394z|/(1 +z) = 0.16 (\u3008|\u0394z|\u3009= 0.51). Including constraints from the radio\u2013far-IR correlation, the accuracy is improved to |\u0394z|/(1 +z) = 0.15 (\u3008|\u0394z|\u3009= 0.45).

", "abstract": "We present a new study of stellar mass in a sample of ~70 submillimeter-selected galaxies (SMGs) with accurate spectroscopic redshifts. We fit combinations of stellar population synthesis models and power laws to the galaxies' observed-frame optical through mid-IR spectral energy distributions (SEDs) to separate stellar emission from non-stellar near-IR continuum. The availability of spectroscopic redshifts significantly enhances our ability to determine unambiguously not only the mass and luminosity of SMGs, but also the presence and contribution of non-stellar emission to their SEDs. By separating the stellar emission from the non-stellar near-IR continuum, we find that ~50% of our sample have non-stellar contributions of less than 10% in rest-frame H band and ~10% of our sample have non-stellar contributions greater than 50%. We find that the K-band luminosity of the non-stellar continuum emission is correlated with hard X-ray luminosity, indicating an active galactic nucleus (AGN) origin of the emission. Upon subtracting this AGN-contributed continuum component from all of the galaxies in our sample, we determine a lower median stellar mass for SMGs than previous studies, ~7 \u00d7 10^(10) M_\u2609. We use constraints of the starburst timescale from molecular gas studies to estimate the amount of fading our sample would undergo if they passively evolve after the starburst terminates. The results suggest that typical SMGs, while among the most massive galaxies at z ~ 2, are likely to produce descendants of similar mass and luminosity to L^* galaxies in the local universe.", "date": "2011-10-20", "date_type": "published", "publication": "Astrophysical Journal", "volume": "740", "number": "2", "publisher": "American Astronomical Society", "pagerange": "Art.

", "abstract": "Many X-ray binaries remain undetected in the mid-infrared, a regime where emission from their compact jets is likely to dominate. Here, we report the detection of the black hole binary GX 339-4 with the Wide-field Infrared Survey Explorer (WISE) during a very bright, hard accretion state in 2010. Combined with a rich contemporaneous multiwavelength data set, clear spectral curvature is found in the infrared, associated with the peak flux density expected from the compact jet. An optically thin slope of ~ \u20130.7 and a jet radiative power of >6 \u00d7 10^(35) erg s^(\u20131) (d/8 kpc)^2 are measured. A ~24 hr WISE light curve shows dramatic variations in mid-infrared spectral slope on timescales at least as short as the satellite orbital period ~95 minutes. There is also significant change during one pair of observations spaced by only 11 s. These variations imply that the spectral break associated with the transition from self-absorbed to optically thin jet synchrotron radiation must be varying across the full wavelength range of ~3-22 \u03bcm that WISE is sensitive to, and more. Based on four-band simultaneous mid-infrared detections, the break is constrained to frequencies of \u22484.6^(+3.5)_(\u20132.0) \u00d7 10^(13) Hz in at least two epochs of observation, consistent with a magnetic field B \u2248 1.5(\u00b1 0.8) \u00d7 10^4 G assuming a single-zone synchrotron emission region.

", "abstract": "The spectral energy distributions (SED) of dusty galaxies at intermediate redshift may look similar to very high-redshift galaxies in the optical/near infrared (NIR) domain. This can lead to the contamination of high-redshift galaxy searches based on broad-band optical/NIR photometry by lower redshift dusty galaxies because both kind of galaxies cannot be distinguished. The contamination rate could be as high as 50%. This work shows how the far-infrared (FIR) domain can help to recognize likely low-z interlopers in an optical/NIR search for high-z galaxies. We analyze the FIR SEDs of two galaxies that are proposed to be very high-redshift (z > 7) dropout candidates based on deep Hawk-I/VLT observations. The FIR SEDs are sampled with PACS/Herschel at 100 and 160\u2009\u03bcm, with SPIRE/Herschel at 250, 350 and 500\u2009\u03bcm and with LABOCA/APEX at 870\u2009\u03bcm. We find that redshifts > 7 would imply extreme FIR SEDs (with dust temperatures >100\u2009K and FIR luminosities >10^(13)\u2009L_\u2299). At z ~ 2, instead, the SEDs of both sources would be compatible with those of typical ultra luminous infrared galaxies or submillimeter galaxies. Considering all available data for these sources from visible to FIR we re-estimate the redshifts and find z ~ 1.6\u20132.5. Owing to the strong spectral breaks observed in these galaxies, standard templates from the literature fail to reproduce the visible-to-near-IR part of the SEDs even when additional extinction is included. These sources strongly resemble dust-obscured galaxies selected in Spitzer observations with extreme visible-to-FIR colors, and the galaxy GN10 at z = 4.

", "abstract": "On behalf of the WISE Science team, we present the discovery of a class of distant dust-enshrouded galaxies with extremely high luminosity. These galaxies are selected to have extreme red colors in the mid-IR using NASA's Wide-field Infrared Survey Explorer (WISE). They are faint in the optical and near-IR, predominantly at z=2-4, and with IR luminosity > 10^(13)L_\u2609, making them Hyper-Luminous Infrared Galaxies (HyLIRGs). SEDs incorporating the WISE, Spitzer, and Herschel PACS and SPIRE photometry indicate hot dust dominates the bolometric luminosity, presumably powered by AGN. Preliminary multi-wavelength follow-up suggests that they are different from normal populations in the local M-sigma relation. Their low source density implies that these objects are either intrinsically rare, or a short-lived phase in a more numerous population. If the latter is the case, these hot, dust-enshrouded galaxies may be an early stage in the interplay between AGN and galaxies.", "date": "2011-10", "date_type": "published", "publisher": "Astronomical Society of the Pacific", "place_of_pub": "San Francisco, CA", "pagerange": "247-250", "id_number": "CaltechAUTHORS:20140130-094336118", "isbn": "978-1-58381-838-1", "book_title": "Galaxy Mergers in an Evolving Universe", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20140130-094336118", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA/JPL/Caltech" } ] }, "local_group": { "items": [ { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" } ] }, "contributors": { "items": [ { "id": "Sun-Wei-Hsin", "name": { "family": "Sun", "given": "Wei-Hsin" } }, { "id": "Xu-C-Kevin", "name": { "family": "Xu", "given": "C.

", "abstract": "We present the results of a gravitational lensing analysis of the bright z_s = 2.957 submillimeter galaxy (SMG) HERMES found in the Herschel/SPIRE science demonstration phase data from the Herschel Multi-tiered Extragalactic Survey (HerMES) project. The high-resolution imaging available in optical and near-IR channels, along with CO emission obtained with the Plateau de Bure Interferometer, allows us to precisely estimate the intrinsic source extension and hence estimate the total lensing magnification to be \u03bc = 10.9 \u00b1 0.7. We measure the half-light radius R_(eff) of the source in the rest-frame near-UV and V bands that characterize the unobscured light coming from stars and find R_(eff),* = [2.0 \u00b1 0.1] kpc, in good agreement with recent studies on the SMG population. This lens model is also used to estimate the size of the gas distribution (R_(eff,gas) = [1.1 \u00b1 0.5] kpc) by mapping back in the source plane the CO (J = 5 \u2192 4) transition line emission. The lens modeling yields a relatively large Einstein radius R_(Ein) = 4\".10 \u00b1 0\".02, corresponding to a deflector velocity dispersion of [483 \u00b1 16] km s^(\u20131). This shows that HERMES is lensed by a galaxy group-size dark matter halo at redshift z_l ~ 0.6. The projected dark matter contribution largely dominates the mass budget within the Einstein radius with f_(dm)(< R_(Ein)) ~ 80%. This fraction reduces to f_(dm)(< R_(eff,G1) \u2243 4.5 kpc) ~ 47% within the effective radius of the main deflecting galaxy of stellar mass M_(*,G1) = [8.5 \u00b1 1.6] \u00d7 10^(11) M_\u2609.

", "abstract": "We compare the emission at multiple wavelengths of an extended Seyfert galaxy sample, including both types of Seyfert nuclei. We use the Caltech Submillimeter Observatory to observe the CO J = 2-1 transition line in a sample of 45 Seyfert galaxies and detect 35 of them. The galaxies are selected by their joint soft X-ray (0.1-2.4 keV) and far-infrared (\u03bb = 60-100 \u03bcm) emission from the ROSAT/IRAS sample. Since the CO line widths (W_(CO)) reflect the orbital motion in the gravitational potential of the host galaxy, we study how the kinematics are affected by the central massive black hole (BH), using the X-ray luminosity. A significant correlation is found between the CO line width and hard (0.3-8 keV from Chandra and XMM-Newton) X-ray luminosity for both types of Seyfert nuclei. Assuming an Eddington accretion to estimate the BH mass (M_(BH)) from the X-ray luminosity, the W_(CO)-L_X) relation establishes a direct connection between the kinematics of the molecular gas of the host galaxy and the nuclear activity, and corroborates the previous studies that show that the CO is a good surrogate for the bulge mass. We also find a tight correlation between the (soft and hard) X-ray and the CO luminosities for both Seyfert types. These results indicate a direct relation between the molecular gas (i.e., star formation activity) of the host galaxy and the nuclear activity. To establish a clear causal connection between molecular gas and the fueling of nuclear activity, high-resolution maps (<100 pc) of the CO emission of our sample will be required and provided in a forthcoming Atacama Large Millimeter Array observation.", "date": "2011-08", "date_type": "published", "publication": "Astrophysical Journal Supplement Series", "volume": "195", "number": "2", "publisher": "American Astronomical Society", "pagerange": "Art.

", "abstract": "We have carried out a survey of the north and south ecliptic poles, EP-N and EP-S, respectively, with the Spitzer Space Telescope and the Wide-field Infrared Survey Explorer (WISE). The primary objective was to cross-calibrate WISE with the Spitzer and Midcourse Space Experiment (MSX) photometric systems by developing a set of calibration stars that are common to these infrared missions. The ecliptic poles were continuous viewing zones for WISE due to its polar-crossing orbit, making these areas ideal for both absolute and internal calibrations. The Spitzer IRAC and MIPS imaging survey covers a complete area of 0.40 deg^2 for the EP-N and 1.28 deg^2 for the EP-S. WISE observed the whole sky in four mid-infrared bands, 3.4, 4.6, 12, and 22 \u03bcm, during its eight-month cryogenic mission, including several hundred ecliptic polar passages; here we report on the highest coverage depths achieved by WISE, an area of ~1.5 deg^2 for both poles. Located close to the center of the EP-N, the Sy-2 galaxy NGC 6552 conveniently functions as a standard calibrator to measure the red response of the 22 \u03bcm channel of WISE. Observations from Spitzer-IRAC/MIPS/IRS-LL and WISE show that the galaxy has a strong red color in the mid-infrared due to star-formation and the presence of an active galactic nucleus (AGN), while over a baseline >1 year the mid-IR photometry of NGC 6552 is shown to vary at a level less than 2%. Combining NGC 6552 with the standard calibrator stars, the achieved photometric accuracy of the WISE calibration, relative to the Spitzer and MSX systems, is 2.4%, 2.8%, 4.5%, and 5.7% for W1 (3.4 \u03bcm), W2 (4.6 \u03bcm), W3 (12 \u03bcm), and W4 (22 \u03bcm), respectively. The WISE photometry is internally stable to better than 0.1% over the cryogenic lifetime of the mission. The secondary objective of the Spitzer-WISE Survey was to explore the poles at greater flux-level depths, exploiting the higher angular resolution Spitzer observations and the exceptionally deep (in total coverage) WISE observations that potentially reach down to the confusion limit of the survey. The rich Spitzer and WISE data sets were used to study the Galactic and extragalactic populations through source counts, color-magnitude and color-color diagrams. As an example of what the data sets facilitate, we have separated stars from galaxies, delineated normal galaxies from power-law-dominated AGNs, and reported on the different fractions of extragalactic populations. In the EP-N, we find an AGN source density of ~260 deg^(\u20132) to a 12 \u03bcm depth of 115 \u03bcJy, representing 15% of the total extragalactic population to this depth, similar to what has been observed for low-luminosity AGNs in other fields.", "date": "2011-07-10", "date_type": "published", "publication": "Astrophysical Journal", "volume": "735", "number": "2", "publisher": "American Astronomical Society", "pagerange": "Art.

Interferometric 880 \u03bcm Submillimeter Array observations resolve at least four images with a large separation of ~9\". A high-resolution adaptive optics K_p image with Keck/NIRC2 clearly shows strong lensing arcs. Follow-up spectroscopy gives a redshift of z = 2.9575, and the lensing model gives a total magnification of \u03bc ~ 11 \u00b1 1. The large image separation allows us to study the multi-wavelength spectral energy distribution (SED) of the lensed source unobscured by the central lensing mass. The far-IR/millimeter-wave SED is well described by a modified blackbody fit with an unusually warm dust temperature, 88 \u00b1 3 K. We derive a lensing-corrected total IR luminosity of (1.43 \u00b1 0.09) \u00d7 10^(13) L_\u2609, implying a star formation rate of ~2500 M_\u2609 yr^(\u20131).

", "abstract": "We examine the rest-frame far-infrared emission from powerful radio sources with 1.4-GHz luminosity densities of\u200225 \u2264 log(L_(1.4)/W Hz^(\u22121)) \u2264 26.5\u2002in the extragalactic\u2002Spitzer\u2002First Look Survey field.

We separate our sources into a moderate,\u20020.4 <\u2002z\u2002< 0.9, and a high,\u20021.2 <\u2002z\u2002< 3.0, redshift sub-sample and we use\u2002Spitzer\u2002observations of a\u2002z\u2002< 0.1\u20023CRR sample as a local comparison. By comparison to numbers from the Square Kilometre Array (SKA) Simulated Skies, we find that our moderate-redshift sample is complete and our high-redshift sample is 14 per cent complete. We constrain the ranges of mean star formation rates (SFRs) to be 3.4\u20134.2, 18\u201341 and\u200280\u2013581 M_\u2299 yr^(\u22121)\u2002for the local, moderate- and high-redshift samples, respectively. Hence, we observe an increase in the mean SFR with increasing redshift which we can parametrize as\u2002\u223c(1 +\u2002z)^Q, where\u2002Q\u2002= 4.2 \u00b1 0.8.

In addition to the COSMOS-survey X-ray to radio data, we report observations of the source with Herschel/PACS (100, 160 \u03bcm), CSO/SHARC II (350 \u03bcm), and CARMA and PdBI (3 mm). We do not detect CO(5 \u2192 4) line emission in the covered redshift ranges, 4.56-4.76 (PdBI/CARMA) and 4.94-5.02 (CARMA). If the line is within this bandwidth, this sets 3\u03c3 upper limits on the gas mass to \u22728 \u00d7 10^9 M_\u2609 and \u22725 \u00d7 10^(10) M_\u2609, respectively (assuming similar conditions as observed in z ~ 2 SMGs). This could be explained by a low CO-excitation in the source. Our analysis of the UV-IR spectral energy distribution of AzTEC 1 shows that it is an extremely young (\u227250 Myr), massive (M * ~ 10^(11) M_\u2609), but compact (\u22722 kpc) galaxy, forming stars at a rate of ~1300 M_\u2609 yr^(\u20131). Our results imply that AzTEC 1 is forming stars in a \"gravitationally bound\" regime in which gravity prohibits the formation of a superwind, leading to matter accumulation within the galaxy and further generations of star formation.", "date": "2011-04-20", "date_type": "published", "publication": "Astrophysical Journal Letters", "volume": "731", "number": "2", "publisher": "American Astronomical Society", "pagerange": "Art.

", "abstract": "The extragalactic background light at far-infrared wavelengths comes from optically faint, dusty, star-forming galaxies in the Universe with star formation rates of a few hundred solar masses per year. These faint, submillimetre galaxies are challenging to study individually because of the relatively poor spatial resolution of far-infrared telescopes. Instead, their average properties can be studied using statistics such as the angular power spectrum of the background intensity variations. A previous attempt at measuring this power spectrum resulted in the suggestion that the clustering amplitude is below the level computed with a simple ansatz based on a halo model. Here we report excess clustering over the linear prediction at arcminute angular scales in the power spectrum\nof brightness fluctuations at 250, 350 and 500 \u00b5m. From this excess, we find that submillimetre galaxies are located in darkmatter haloes with a minimum mass, M_(min), such that log_(10)[M_(min)/M_\u2299] = 11.5^(+0.7)_(-0.2) at 350 \u00b5m, where M_\u2299 is the solar mass. This minimum dark matter halo mass corresponds to the most efficient mass scale for star formation in the Universe, and is lower than that predicted by semi-analytical models for galaxy formation.", "date": "2011-02-24", "date_type": "published", "publication": "Nature", "volume": "470", "number": "7335", "publisher": "Nature Publishing Group", "pagerange": "510-512", "id_number": "CaltechAUTHORS:20110314-094552984", "issn": "0028-0836", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20110314-094552984", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Canadian Space Agency (CSA)" }, { "agency": "National Astronomical Observatories, Chinese Academy of Sciences (NAOC)" }, { "agency": "Commissariat \u00e0 l'Energie Atomique (CEA)" }, { "agency": "Centre National d'\u00c9tudes Spatiales (CNES)" }, { "agency": "Centre National de la Recherche Scientifique (CNRS)" }, { "agency": "Agenzia Spaziale Italiana (ASI)" }, { "agency": "Ministerio de Ciencia e Innovaci\u00f3n (MCINN)" }, { "agency": "Swedish National Space Board (SNSB)" }, { "agency": "Science and Technology Facilities Council (STFC)" }, { "agency": "NASA" } ] }, "local_group": { "items": [ { "id": "TAPIR" }, { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" } ] }, "doi": "10.1038/nature09771", "primary_object": { "basename": "nature09771-s1.pdf", "url": "https://authors.library.caltech.edu/records/gv0gy-paj42/files/nature09771-s1.pdf" }, "resource_type": "article", "pub_year": "2011", "author_list": "Amblard, Alexandre; Cooray, Asantha; et el." }, { "id": "https://authors.library.caltech.eduhttps://authors.library.caltech.edu/records/gqqjf-4rw11", "eprint_id": 21674, "eprint_status": "archive", "datestamp": "2023-08-19 04:32:05", "lastmod": "2023-10-21 00:13:49", "type": "article", "metadata_visibility": "show", "creators": { "items": [ { "id": "Wright-E-L", "name": { "family": "Wright", "given": "Edward L." }, "orcid": "0000-0001-5058-1593" }, { "id": "Cutri-R-M", "name": { "family": "Cutri", "given": "Roc M." }, "orcid": "0000-0002-0077-2305" }, { "id": "Jarrett-T-H", "name": { "family": "Jarrett", "given": "Thomas" }, "orcid": "0000-0002-4939-734X" }, { "id": "Kirkpatrick-J-D", "name": { "family": "Kirkpatrick", "given": "J.

", "abstract": "We analyze subarcsecond resolution interferometric CO line data for 12 submillimeter-luminous (S_(850 \u03bcm) \u2265 5 mJy) galaxies with redshifts between 1 and 3, presenting new data for 4 of them. Morphologically and kinematically, most of the 12 systems appear to be major mergers. Five of them are well-resolved binary systems, and seven are compact or poorly resolved. Of the four binary systems for which mass measurements for both separate components can be made, all have mass ratios of 1:3 or closer. Furthermore, comparison of the ratio of compact to binary systems with that observed in local ULIRGs indicates that at least a significant fraction of the compact submillimeter-luminous galaxies (SMGs) must also be late-stage mergers. In addition, the dynamical and gas masses we derive are most consistent with the lower end of the range of stellar masses published for these systems, favoring cosmological models in which SMGs result from mergers. These results all point to the same conclusion that most of the bright SMGs with L_(IR) \u2273 5 \u00d7 10^(12) L_\u2609 are likely major mergers.", "date": "2010-11-20", "date_type": "published", "publication": "Astrophysical Journal", "volume": "724", "number": "1", "publisher": "American Astronomical Society", "pagerange": "233-243", "id_number": "CaltechAUTHORS:20101206-095558639", "issn": "0004-637X", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20101206-095558639", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Institute for Defense Analysis (IDA)" }, { "agency": "Science and Technology Facilities Council (STFC)" } ] }, "doi": "10.1088/0004-637X/724/1/233", "primary_object": { "basename": "Engel2010p12061Astrophys_J.pdf", "url": "https://authors.library.caltech.edu/records/epgb3-nft21/files/Engel2010p12061Astrophys_J.pdf" }, "resource_type": "article", "pub_year": "2010", "author_list": "Engel, H.; Tacconi, L.

We explore whether existing models for starbursts, quiescent star-forming galaxies and active galactic nucleus dust tori are able to model the full range of SEDs measured with Herschel. We find that while many galaxies (~56 per cent) are well fitted with the templates used to fit IRAS, Infrared Space Observatory (ISO) and Spitzer sources, for about half the galaxies two new templates are required: quiescent ('cirrus') models with colder (10\u201320 K) dust and a young starburst model with higher optical depth than Arp 220. Predictions of submillimetre fluxes based on model fits to 4.5\u201324 \u03bcm data agree rather poorly with the observed fluxes, but the agreement is better for fits to 4.5\u201370 \u03bcm data.

Infrared (IR) luminosity (L_(IR)) and dust temperature (T_dust) of galaxies are derived from the spectral energy distribution fit of the far-IR (FIR) flux densities obtained with the PACS and SPIRE instruments onboard Herschel. As a reference sample, we also obtain IR luminosities and dust temperatures of local galaxies at z < 0.1 using AKARI and IRAS data in the field of the Sloan Digital Sky Survey. We compare the L_(IR)\u2013T_dust relation between the two samples and find that the median Tdust of Herschel-selected galaxies at z \u2273 0.5 with L_(IR) \u2273 5 \u00d7 10^(10) L_\u2299 appears to be 2\u20135 K colder than that of AKARI-selected local galaxies with similar luminosities, and the dispersion in T_dust for high-z galaxies increases with L_(IR) due to the existence of cold galaxies that are not seen among local galaxies. We show that this large dispersion of the L_(IR)\u2212T_dust relation can bridge the gap between local star-forming galaxies and high-z submillimetre galaxies (SMGs). We also find that three SMGs with very low T_dust\u2002(\u227220 K) covered in this study have close neighbouring sources with similar 24-\u03bcm brightness, which could lead to an overestimation of FIR/(sub)millimetre fluxes of the SMGs.", "date": "2010-11", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "409", "number": "1", "publisher": "Royal Astronomical Society", "pagerange": "75-82", "id_number": "CaltechAUTHORS:20110103-110253076", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20110103-110253076", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Bundesministerium f\u00fcr Verkehr, Innovation und Technologie (BMVIT)" }, { "agency": "European Space Agency (ESA) PROgramme for the Development of scientific Experiments (PRODEX) (Belgium)" }, { "agency": "Commissariat \u00e0 l'Energie Atomique (CEA)" }, { "agency": "Deutsches Zentrum f\u00fcr Luft- und Raumfahrt (DLR)" }, { "agency": "Agenzia Spaziale Italiana (ASI)" }, { "agency": "Comisi\u00f3n Interministerial de Ciencia y Tecnolog\u00eda (CICT)" }, { "agency": "Canadian Space Agency (CSA)" }, { "agency": "National Astronomical Observatories, Chinese Academy of Sciences (NAOC)" }, { "agency": "Laboratoire d'Astrophysique de Marseille (LAM)" }, { "agency": "Ministerio de Ciencia e Innovaci\u00f3n (MCINN)" }, { "agency": "Stockholm Observatory" }, { "agency": "Science and Technology Facilities Council (STFC)" }, { "agency": "NASA" }, { "agency": "National Research Foundation of Korea", "grant_number": "R01-2007-000-20336-0" }, { "agency": "Centre National d'\u00c9tudes Spatiales (CNES)" }, { "agency": "Ministerio de Ciencia Y Tecnologia (MCYT)" }, { "agency": "Istituto Nazionale di Astrofisica (INAF)" } ] }, "local_group": { "items": [ { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" }, { "id": "TAPIR" } ] }, "doi": "10.1111/j.1365-2966.2010.17645.x", "primary_object": { "basename": "1009.1058.pdf", "url": "https://authors.library.caltech.edu/records/cexj5-d5d95/files/1009.1058.pdf" }, "related_objects": [ { "basename": "Hwang2010p12112Mon_Not_R_Astron_Soc.pdf", "url": "https://authors.library.caltech.edu/records/cexj5-d5d95/files/Hwang2010p12112Mon_Not_R_Astron_Soc.pdf" } ], "resource_type": "article", "pub_year": "2010", "author_list": "Hwang, H.

", "abstract": "We present first results of a study of the submillimetre (submm) (rest-frame far-infrared) properties of z ~ 3 Lyman break galaxies (LBGs) and their lower redshift counterparts BX/BM galaxies, based on Herschel-SPIRE observations of the Northern field of the Great Observatories Origins Deep Survey (GOODS-N). We use stacking analysis to determine the properties of LBGs well below the current limit of the survey. Although LBGs are not detected individually, stacking the infrared luminous LBGs (those detected with Spitzer at 24 \u03bcm) yields a statistically significant submm detection with mean flux \u3008S_(250)\u3009= 5.9 \u00b1 1.4 mJy confirming the power of SPIRE in detecting UV-selected high-redshift galaxies at submm wavelengths. In comparison, the Spitzer 24 \u03bcm detected BX/BM galaxies appear fainter with a stacked value of\u3008S_(250)\u3009= 2.7 \u00b1 0.8 mJy. By fitting the spectral energy distributions (SEDs) we derive median infrared luminosities, L_(IR), of 2.8 \u00d7 10^(12) L_\u2299 and 1.5 \u00d7 10^(11) L_\u2299 for z ~ 3 LBGs and BX/BMs, respectively. We find that LIR estimates derived from present measurements are in good agreement with those based on UV data for z ~ 2 BX/BM galaxies, unlike the case for z ~ 3 infrared luminous LBGs where the UV underestimates the true L_(IR). Although sample selection effects may influence this result we suggest that differences in physical properties (such as morphologies, dust distribution and extent of star-forming regions) between z ~ 3 LBGs and z ~ 2 BX/BMs may also play a significant role.", "date": "2010-11", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "409", "number": "1", "publisher": "Royal Astronomical Society", "pagerange": "L7-L12", "id_number": "CaltechAUTHORS:20110509-110943988", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20110509-110943988", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Canadian Space Agency (CSA)" }, { "agency": "National Astronomical Observatories, Chinese Academy of Sciences (NAOC)" }, { "agency": "Commissariat \u00e0 l'Energie Atomique (CEA)" }, { "agency": "Centre National d'\u00c9tudes Spatiales (CNES)" }, { "agency": "Centre National de la Recherche Scientifique (CNRS)" }, { "agency": "Agenzia Spaziale Italiana (ASI)" }, { "agency": "Ministerio de Ciencia e Innovaci\u00f3n (MCINN)" }, { "agency": "Swedish National Space Board (SNSB)" }, { "agency": "Science and Technology Facilities Council (STFC)" }, { "agency": "NASA" } ] }, "local_group": { "items": [ { "id": "TAPIR" }, { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" } ] }, "doi": "10.1111/j.1745-3933.2010.00950.x", "primary_object": { "basename": "Rigopoulou2010p13726Mon_Not_R_Astron_Soc.pdf", "url": "https://authors.library.caltech.edu/records/75c17-eas67/files/Rigopoulou2010p13726Mon_Not_R_Astron_Soc.pdf" }, "resource_type": "article", "pub_year": "2010", "author_list": "Rigopoulou, D.; Blain, A.; et el." }, { "id": "https://authors.library.caltech.eduhttps://authors.library.caltech.edu/records/j60ta-t8a10", "eprint_id": 21323, "eprint_status": "archive", "datestamp": "2023-08-22 01:15:33", "lastmod": "2023-10-20 23:56:23", "type": "article", "metadata_visibility": "show", "creators": { "items": [ { "id": "Levenson-L", "name": { "family": "Levenson", "given": "L." } }, { "id": "Zemcov-M", "name": { "family": "Zemcov", "given": "M." }, "orcid": "0000-0001-8253-1451" }, { "id": "Blain-A-W", "name": { "family": "Blain", "given": "A." }, "orcid": "0000-0001-7489-5167" }, { "id": "Bock-J-J", "name": { "family": "Bock", "given": "J." }, "orcid": "0000-0002-5710-5212" }, { "id": "Cooray-A", "name": { "family": "Cooray", "given": "A." }, "orcid": "0000-0002-3892-0190" }, { "id": "Dowell-C-D", "name": { "family": "Dowell", "given": "C.

We specify here the SHIM algorithm and outline the various tests that were performed to determine and characterize the quality of the maps and verify that the astrometry, point source flux and power on all relevant angular scales meet the needs of the HerMES science goals. These include multiple jackknife tests, determination of the map transfer function and detailed examination of the power spectra of both sky and jackknife maps.

Deep Herschel-Spectral and Photometric Imaging Receiver (SPIRE) images designed to detect and characterize the galaxies that comprise this background are highly confused, such that the bulk lies below the classical confusion limit. We analyse three fields from the Herschel Multi-tiered Extragalactic Survey (HerMES) programme in all three SPIRE bands (250, 350 and 500 \u03bcm); parametrized galaxy number count models are derived to a depth of ~2 mJy beam^(\u22121), approximately four times the depth of previous analyses at these wavelengths, using a probability of deflection [P(D)] approach for comparison to theoretical number count models. Our fits account for 64, 60 and 43 per cent of the far-infrared background in the three bands. The number counts are consistent with those based on individually detected SPIRE sources, but generally inconsistent with most galaxy number count models, which generically overpredict the number of bright galaxies and are not as steep as the P(D)-derived number counts. Clear evidence is found for a break in the slope of the differential number counts at low flux densities. Systematic effects in the P(D) analysis are explored. We find that the effects of clustering have a small impact on the data, and the largest identified systematic error arises from uncertainties in the SPIRE beam.", "date": "2010-11", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "409", "number": "1", "publisher": "Royal Astronomical Society", "pagerange": "109-121", "id_number": "CaltechAUTHORS:20101217-091446952", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20101217-091446952", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "1394366" } ] }, "local_group": { "items": [ { "id": "TAPIR" }, { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" } ] }, "doi": "10.1111/j.1365-2966.2010.17781.x", "primary_object": { "basename": "Glenn2010p12115Mon_Not_R_Astron_Soc.pdf", "url": "https://authors.library.caltech.edu/records/2qmem-vh395/files/Glenn2010p12115Mon_Not_R_Astron_Soc.pdf" }, "resource_type": "article", "pub_year": "2010", "author_list": "Glenn, J.; Blain, A.; et el." }, { "id": "https://authors.library.caltech.eduhttps://authors.library.caltech.edu/records/ny3sn-gcj60", "eprint_id": 21737, "eprint_status": "archive", "datestamp": "2023-08-19 04:15:08", "lastmod": "2023-10-21 00:17:03", "type": "article", "metadata_visibility": "show", "creators": { "items": [ { "id": "Magdis-G-E", "name": { "family": "Magdis", "given": "G.

We derive robust estimates of infrared luminosities\n(L_(IR)) and dust temperatures (T_d) of the population and find that while the luminosities in our\nsample span less than an order of magnitude (12.24 \u2264 log(L_(IR)/L_\u2299) \u2264 12.94), they cover\na wide range of dust temperatures (25 \u2264 T_d \u2264 62 K). Galaxies in our sample range from\nthose that are as cold as high-z submillimetre galaxies (SMGs) to those that are as warm\nas optically faint radio galaxies (OFRGs) and local ULIRGs. Nevertheless, our sample has\nmedian T_d = 42.3 K, filling the gap between SMGs and OFRGs, bridging the two populations.\nWe demonstrate that a significant fraction of our sample would be missed from ground-based\n(sub)mm surveys (850\u20131200 \u03bcm), showing that the latter introduce a bias towards the detection\nof colder sources.

We build flux-limited 250-\u03bcm samples of sources at redshift\u2002z\u2002< 1, cross-matched with the\u2002Spitzer/MIPS and\u2002GALEX\u2002catalogues. About 60 per cent of the\u2002Herschel\u2002sources are detected in UV. The total IR luminosities,\u2002L_(IR), of the sources are estimated using a spectral energy distribution (SED) fitting code that fits to fluxes between 24 and 500 \u03bcm. Dust attenuation is discussed on the basis of commonly used diagnostics: the\u2002L_(IR)/L_(UV)\u2002ratio and the slope, \u03b2, of the UV continuum. A mean dust attenuation\u2002A_(UV)\u2002of\u2002\u2243\u20023 mag is measured in the samples.\u2002L_(IR)/L_(UV)\u2002is found to correlate with\u2002L_(IR).

Our galaxy samples span a large range of \u03b2 and\u2002L_(IR)/L_(UV)\u2002values which, for the most part, are distributed between the ranges defined by the relations found locally for starburst and normal star-forming galaxies. As a consequence the recipe commonly applied to local starbursts is found to overestimate the dust attenuation correction in our galaxy sample by a factor of ~2\u20133. The SFRs deduced from\u2002L_(IR)\u2002are found to account for about 90 per cent of the total SFR; this percentage drops to 71 per cent for galaxies with\u2002SFR < 1 M_\u2299\u2002yr^(-1) (or\u2002L_(RI) < 10^(10) L_\u2299).

", "abstract": "We present the cross-identification and source photometry techniques used to process Herschel SPIRE imaging taken as part of the Herschel Multi-Tiered Extragalactic Survey (HerMES). Cross-identifications are performed in map-space so as to minimize source-blending effects. We make use of a combination of linear inversion and model selection techniques to produce reliable cross-identification catalogues based on Spitzer MIPS 24-\u03bcm source positions. Testing on simulations and real Herschel observations shows that this approach gives robust results for even the faintest sources (S_(250) ~10 mJy). We apply our new technique to HerMES SPIRE observations taken as part of the science demonstration phase of Herschel. For our real SPIRE observations, we show that, for bright unconfused sources, our flux density estimates are in good agreement with those produced via more traditional point source detection methods (SUSSEXtractor) by Smith et al. When compared to the measured number density of sources in the SPIRE bands, we show that our method allows the recovery of a larger fraction of faint sources than these traditional methods. However, this completeness is heavily dependent on the relative depth of the existing 24-\u03bcm catalogues and SPIRE imaging. Using our deepest multiwavelength data set in the GOODS-N, we estimate that the use of shallow 24-\u03bcm catalogues in our other fields introduces an incompleteness at faint levels of between 20\u201340 per cent at 250 \u03bcm.", "date": "2010-11", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "409", "number": "1", "publisher": "Royal Astronomical Society", "pagerange": "48-65", "id_number": "CaltechAUTHORS:20110105-153945195", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20110105-153945195", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Science and Technology Facilities Council (STFC)", "grant_number": "ST/F002858/1" } ] }, "local_group": { "items": [ { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" }, { "id": "TAPIR" } ] }, "doi": "10.1111/j.1365-2966.2010.17634.x", "primary_object": { "basename": "1009.1658.pdf", "url": "https://authors.library.caltech.edu/records/w46bb-y4x92/files/1009.1658.pdf" }, "related_objects": [ { "basename": "Roseboom2010p12118Mon_Not_R_Astron_Soc.pdf", "url": "https://authors.library.caltech.edu/records/w46bb-y4x92/files/Roseboom2010p12118Mon_Not_R_Astron_Soc.pdf" } ], "resource_type": "article", "pub_year": "2010", "author_list": "Roseboom, I.

", "abstract": "We present the first spectroscopic analysis of the faint M31 satellite galaxies, And XI and And XIII, as well as a re-analysis of existing spectroscopic data for two further faint companions, And IX (correcting for an error in earlier geometric modelling that caused a misclassification of member stars in previous work) and And XII. By combining data obtained using the Deep Imaging Multi-Object Spectrograph (DEIMOS) mounted on the Keck II telescope with deep photometry from the Suprime-Cam instrument on Subaru, we have identified the most probable members for each of the satellites based on their radial velocities (precise to several km s^(-1) down to i ~22), distance from the centre of the dwarf spheroidal galaxies (dSphs) and their photometric [Fe/H]. Using both the photometric and spectroscopic data, we have also calculated global properties for the dwarfs, such as systemic velocities, metallicities and half-light radii. We find each dwarf to be very metal poor ([Fe/H]~\u22122 both photometrically and spectroscopically, from their stacked spectrum), and as such, they continue to follow the luminosity\u2013metallicity relationship established with brighter dwarfs. We are unable to resolve dispersion for And XI due to small sample size and low signal-to-noise ratio, but we set a 1\u03c3 upper limit of \u03c3_v < 4.5 km s^(\u22121). For And IX, And XII and And XIII we resolve velocity dispersions of \u03c3_v= 4.5^(+3.6)_(\u22123.4), 2.6^(+5.1)_(\u22122.6) and 9.7^(+8.9)_(\u22124.5) km s^(\u22121), though we note that the dispersion for And XIII is based on just three stars. We derive masses within the half-light radii for these galaxies of 6.2^(+5.3)_(\u22125.1)\u00d7 10^6, 2.4^(+6.5)_(\u22122.4)\u00d7 10^6 and 1.1^(+1.4)_(\u22120.7)\u00d7 10_7 M_\u2299, respectively. We discuss each satellite in the context of the Mateo relations for dSphs, and in reference to the universal halo profiles established for Milky Way dwarfs. Both And IX and And XII fall below the universal halo profiles of Walker et al., indicating that they are less massive than would be expected for objects of their half-light radius. When combined with the findings of McConnachie & Irwin, which reveal that the M31 satellites are twice as extended (in terms of both half-light and tidal radii) as their Milky Way counterparts, these results suggest that the satellite population of the Andromeda system could inhabit haloes that with regard to their central densities are significantly different from those of the Milky Way.", "date": "2010-10-01", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "407", "number": "4", "publisher": "Royal Astronomical Society", "pagerange": "2411-2433", "id_number": "CaltechAUTHORS:20101026-084650741", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20101026-084650741", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "W.

At the faint end of the distribution, direct detection and counting of galaxies are not possible.

We have used the largest catalog of sub-mm-selected sources along the line of sight to galaxy clusters to estimate the faint end of the 850 \u03bcm number counts; integrating to S = 0.10 mJy, the equivalent flux density at 850 \u03bcm is \u03bdI_\u03bd = 0.24 \u00b1 0.03 nW m^(\u20132) sr^(\u20131).

", "abstract": "We present ultra-deep mid-infrared spectra of 48 infrared-luminous galaxies in the GOODS-south field obtained with the Infrared Spectrograph on the Spitzer Space Telescope. These galaxies are selected among faint infrared sources (0.14-0.5 mJy at 24 \u03bcm) in two redshift bins (0.76-1.05 and 1.75-2.4) to sample the major contributors to the cosmic infrared background at the most active epochs. We estimate redshifts for 92% of the sample using polycyclic aromatic (PAH) and Si absorption features obtaining, in particular, eight new redshifts difficult to measure from ground-based observations. Only a few of these galaxies (5% at z ~ 1 and 12% at z ~ 2) have their total infrared luminosity dominated by emission from active galactic nuclei (AGNs). The averaged mid-IR spectrum of the z ~ 1 luminous infrared galaxies (LIRGs) is a very good match to the averaged spectrum of local starbursts. The averaged spectrum of the z ~ 2 ultra-luminous infrared galaxies (ULIRGs), because of a deeper Si absorption, is better fitted by the averaged spectrum of H II-like local ULIRGs. Combining this sample with other published data, we find that 6.2 \u03bcm PAH equivalent widths (EW) reach a plateau of ~ 1 \u03bcm for L 24 \u03bcm \u227e 10^(11) L_\u2299. At higher luminosities, EW_(6.2 \u03bcm) anti-correlates with L _(24 \u03bcm). Intriguingly, high-z ULIRGs and sub-millimeter galaxies (SMGs) lie above the local EW_(6.2 \u03bcm)-L_(24 \u03bcm) relationship suggesting that, at a given luminosity, high-z ULIRGs have AGN contributions to their dust emission lower than those of local counterparts. A quantitative analysis of their morphology shows that most of the luminous IR galaxies have morphologies similar to those of IR-quiet galaxies at the same redshift. All z ~ 2 ULIRGs of our sample are IR-excess BzK galaxies and most of them have L_(FIR)/L_(1600 \u00c5) ratios higher than those of starburst galaxies at a given UV slope. The \"IR excess\" is mostly due to strong 7.7 \u03bcm PAH emission and underestimation of UV dust extinction. On the basis of the AGN-powered L_(6 \u03bcm) continuum measured directly from the mid-IR spectra, we estimate an average intrinsic X-ray AGN luminosity of L_(2\u201310 keV) = (0.1\u00b1 0.6)\u00d7 10^(43) erg s^(\u20131), a value substantially lower than the prediction by Daddi et al.", "date": "2010-08-10", "date_type": "published", "publication": "Astrophysical Journal", "volume": "719", "number": "1", "publisher": "American Astronomical Society", "pagerange": "425-450", "id_number": "CaltechAUTHORS:20100823-143138995", "issn": "0004-637X", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20100823-143138995", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA" }, { "agency": "W.

", "abstract": "Nuclear and starburst activity are known to often occur concomitantly. Herschel-SPIRE provides sampling of the far-infrared (FIR) spectral energy distributions (SEDs) of type 1 and type 2 AGN, allowing for the separation between the hot dust (torus) and cold dust (starburst) emission. We study large samples of spectroscopically confirmed type 1 and type 2 AGN lying within the Herschel Multi-tiered Extragalactic Survey (HerMES) fields observed during the science demonstration phase, aiming to understand their FIR colour distributions and constrain their starburst contributions. We find that one third of the spectroscopically confirmed AGN in the HerMES fields have 5\u03c3 detections at 250\u2009\u03bcm, in agreement with previous (sub)mm AGN studies. Their combined Spitzer-MIPS and Herschel-SPIRE colours (specifically S_(250)/S_(70) vs S_(70)/S_(24)) quite clearly separate them from the non-AGN, star forming galaxy population, as their 24 \u03bcm flux is dominated by the hot torus emission. However, their SPIRE colours alone do not differ from those of non-AGN galaxies. SED fitting shows that all those AGN need a starburst component to fully account for their FIR emission. For objects at z > 2 we find a correlation between the infrared luminosity attributed to the starburst component, LSB, and the AGN accretion luminosity, L_(acc), with L_(SB) \u221d L_(acc)^(0.35). Type 2 AGN detected at 250\u2009\u03bcm show on average higher LSB than type 1 objects but their number is still too low to establish whether this trend indicates stronger star formation activity.", "date": "2010-07", "date_type": "published", "publication": "Astronomy and Astrophysics", "volume": "518", "publisher": "EDP Sciences", "pagerange": "L33", "id_number": "CaltechAUTHORS:20101115-102122698", "issn": "0004-6361", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20101115-102122698", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Canadian Space Agency (CSA)" }, { "agency": "National Astronomical Observatories, Chinese Academy of Sciences (NAOC)" }, { "agency": "Commissariat \u00e0 l'Energie Atomique (CEA)" }, { "agency": "Centre National d'\u00c9tudes Spatiales (CNES)" }, { "agency": "Centre National de la Recherche Scientifique (CNRS)" }, { "agency": "Agenzia Spaziale Italiana (ASI)" }, { "agency": "Ministerio de Ciencia e Innovaci\u00f3n (MCINN)" }, { "agency": "Stockholm Observatory" }, { "agency": "Science and Technology Facilities Council (STFC)" }, { "agency": "NASA" } ] }, "local_group": { "items": [ { "id": "TAPIR" }, { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" } ] }, "doi": "10.1051/0004-6361/201014679", "primary_object": { "basename": "Hatziminaoglou2010p11864Astron_Astrophys.pdf", "url": "https://authors.library.caltech.edu/records/54sf3-dwk05/files/Hatziminaoglou2010p11864Astron_Astrophys.pdf" }, "resource_type": "article", "pub_year": "2010", "author_list": "Hatziminaoglou, E.; Blain, A.; et el." }, { "id": "https://authors.library.caltech.eduhttps://authors.library.caltech.edu/records/vfyg7-a2f51", "eprint_id": 21083, "eprint_status": "archive", "datestamp": "2023-08-19 03:01:17", "lastmod": "2023-10-20 23:45:00", "type": "article", "metadata_visibility": "show", "creators": { "items": [ { "id": "Cooray-A", "name": { "family": "Cooray", "given": "A." }, "orcid": "0000-0002-3892-0190" }, { "id": "Blain-A-W", "name": { "family": "Blain", "given": "A." }, "orcid": "0000-0001-7489-5167" }, { "id": "Bock-J-J", "name": { "family": "Bock", "given": "J.

We compare these with expectations from the literature and discuss\nassociated uncertainties and biases in the SPIRE data. We identify a 500 \u03bcm flux limited selection of sources from the HerMES point source catalogue that appears free from neighbouring/blended sources in all three SPIRE bands. We compare the colours with redshift tracks of various\ncontemporary models. Based on these spectral templates we show that regions corresponding to specific population types and redshifts can be identified better in colour-flux space. The redshift tracks as well as the colour-flux plots imply a majority of detected objects with redshifts at\n1 < z < 3.5, somewhat depending on the group of model SEDs used. We also find that a population of sources with S_(250)/S_(350) < 0.8 at fluxes above 50 mJy as observed by SPIRE are not well represented by contemporary models and could consist of a mix of cold and lensed galaxies.", "date": "2010-07", "date_type": "published", "publication": "Astronomy and Astrophysics", "volume": "518", "publisher": "EDP Sciences", "pagerange": "Art.

H-ATLAS alone statistically detects the quasars in its survey area at >5\u03c3 at 250,350 and 500\u2009\u03bcm. From the compilation as a whole we find striking evidence of downsizing in quasar host galaxy formation: low-luminosity quasars with absolute magnitudes in the range -22 > I_(AB) > -24 have a comoving star formation rate (derived from 100\u2009\u03bcm rest-frame luminosities) peaking between redshifts of 1 and 2, while high-luminosity quasars with I_(AB) < -26 have a maximum contribution to the star formation density at z ~ 3.

", "abstract": "We present a detailed analysis of the far-infrared (-IR) properties of the bright, lensed, z = 2.3, submillimetre-selected galaxy (SMG), SMM\u2009J2135-0102 (hereafter SMM\u2009J2135), using new observations with Herschel, SCUBA-2 and the Very Large Array (VLA). These data allow us to constrain the galaxy's spectral energy distribution (SED) and show that it has an intrinsic rest-frame 8-1000-\u03bcm luminosity, L_(bol), of (2.3\u00b10.2) \u00d7 10^(12) L_\u2609 and a likely star-formation rate (SFR) of ~400 yr-1. The galaxy sits on the far-IR/radio correlation for far-IR-selected galaxies. At \u227370 \u03bcm, the SED can be described adequately by dust components with dust temperatures, T_d ~ 30 and 60 k. Using SPIRE's Fourier- transform spectrometer (FTS) we report a detection of the [C ii]\u2009158 \u03bcm cooling line. If the [C ii], CO and far-IR continuum arise in photo-dissociation regions (PDRs), we derive a characteristic gas density, n ~ 10^3 cm^(-3), and a far-ultraviolet (-UV) radiation field, G_0, 10^(3)\u00d7 stronger than the Milky Way. L_[CII]/L_(bol) is significantly higher than in local ultra-luminous IR galaxies (ULIRGs) but similar to the values found in local star-forming galaxies and starburst nuclei. This is consistent with SMM\u2009J2135 being powered by starburst clumps distributed across ~2 kpc, evidence that SMGs are not simply scaled-up ULIRGs. Our results show that SPIRE's FTS has the ability to measure the redshifts of distant, obscured galaxies via the blind detection of atomic cooling lines, but it will not be competitive with ground-based CO-line searches. It will, however, allow detailed study of the integrated properties of high-redshift galaxies, as well as the chemistry of their interstellar medium (ISM), once more suitably bright candidates have been found.", "date": "2010-07", "date_type": "published", "publication": "Astronomy and Astrophysics", "volume": "518", "publisher": "EDP Sciences", "pagerange": "L35", "id_number": "CaltechAUTHORS:20101119-104348447", "issn": "0004-6361", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20101119-104348447", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Canadian Space Agency (CSA)" }, { "agency": "National Astronomical Observatories, Chinese Academy of Sciences (NAOC)" }, { "agency": "Commissariat \u00e0 l'\u00c9nergie Atomique (CEA) (France)" }, { "agency": "Centre National d'Etudes Spatiales (CNES) (France)" }, { "agency": "Centre National de la Recherche Scientifique (CNRS) (France)" }, { "agency": "Agenzia Spaziale Italiana (ASI)" }, { "agency": "Ministerio de Ciencia e Innovaci\u00f3n (MICIIN) (Spain)" }, { "agency": "Swedish National Space Board (SNSB)" }, { "agency": "Science and Technology Facilities Council (STFC)" }, { "agency": "NASA" } ] }, "doi": "10.1051/0004-6361/201014548", "primary_object": { "basename": "Ivison2010p11859Astron_Astrophys.pdf", "url": "https://authors.library.caltech.edu/records/wvgec-c7590/files/Ivison2010p11859Astron_Astrophys.pdf" }, "resource_type": "article", "pub_year": "2010", "author_list": "Ivison, R.

", "abstract": "The Herschel Space Observatory enables us to accurately measure the bolometric output of starburst galaxies and active galactic nuclei (AGN) by directly sampling the peak of their far-infrared (IR) emission. Here we examine whether the spectral energy distribution (SED) and dust temperature of galaxies have strongly evolved over the last 80% of the age of the Universe. We discuss possible consequences for the determination of starformation\nrates (SFR) and any evidence for a major change in their star-formation properties. We use Herschel deep extragalactic surveys from 100 to 500 \u03bcm to compute total IR luminosities in galaxies down to the faintest levels, using PACS and SPIRE in the GOODS-North field (PEP and\nHerMES key programs). An extension to fainter luminosities is done by stacking images on 24 \u03bcm prior positions. We show that measurements in the SPIRE bands can be used below the statistical confusion limit if information at higher spatial resolution is used, e.g. at 24 \u03bcm, to identify\n\"isolated\" galaxies whose flux is not boosted by bright neighbors. Below z ~ 1.5, mid-IR extrapolations are correct for star-forming galaxies with a dispersion of only 40% (0.15 dex), therefore similar to z ~ 0 galaxies, over three decades in luminosity below the regime of ultra-luminous IR galaxies (ULIRGs, L_(IR) \u2265 10^(12) L_\u2299). This narrow distribution is puzzling when considering the range of physical processes that could have affected the SED of these galaxies. Extrapolations from only one of the 160 \u03bcm, 250 \u03bcm or 350 \u03bcm bands alone tend to overestimate the total IR luminosity. This may be explained by the lack of far-IR constraints around and above ~150 \u03bcm (rest-frame) before Herschel on those templates. We also note that the dust temperature of luminous IR galaxies (LIRGs, L_(IR) \u2265 10^(11) L_\u2299) around z ~ 1 is mildly colder by 10\u201315% than their local analogs and up to 20% for ULIRGs at z ~ 1.6 (using a single modified blackbody-fit to the peak far-IR emission with an emissivity index of \u03b2 = 1.5). Above z = 1.5, distant galaxies are found to exhibit a substantially larger mid- over far-IR ratio, which could either result from stronger broad emission lines or warm dust continuum heated by a hidden AGN. Two thirds of the AGNs identified in the field with a measured redshift exhibit the same behavior as purely star-forming galaxies. Hence a large fraction of AGNs harbor coeval star formation at very high SFR and in conditions similar to purely star-forming galaxies.", "date": "2010-07", "date_type": "published", "publication": "Astronomy and Astrophysics", "volume": "518", "publisher": "EDP Sciences", "pagerange": "Art.

Determining the local luminosity function in the submillimeter range can help to better constrain in particular the bolometric luminosity density in the local Universe, and Herschel offers the first opportunity to do so in an unbiased way by imaging large sky areas at several submillimeter wavelengths. We present the first Herschel measurement of the submillimeter 0 < z < 0.2 local luminosity function and infrared bolometric (8\u20131000 \u03bcm) local luminosity density based on SPIRE data from the HerMES Herschel key program over 14.7 deg^2.

The strong gravitational lensing power of these clusters will enable us to penetrate through the confusion noise, which sets the ultimate limit on our ability to probe the\nUniverse with Herschel. Here we present an overview of our survey and a summary of the major results from our science demonstration phase (SDP) observations of the Bullet cluster (z = 0.297). The SDP data are rich and allow us to study not only the background high-redshift galaxies\n(e.g., strongly lensed and distorted galaxies at z = 2.8 and 3.2) but also the properties of cluster-member galaxies. Our preliminary analysis shows a great diversity of far-infrared/submillimeter spectral energy distributions (SEDs), indicating that we have much to learn with Herschel about the properties of galaxy SEDs. We have also detected the Sunyaev-Zel'dovich (SZ) effect increment with the SPIRE data.

We use flux-limited 250-\u03bcm and 1.4-GHz samples, obtained using Herschel and the Very Large Array (VLA) in GOODS-North (-N). We determine bolometric IR output using ten bands spanning \u03bb_(obs) = 24\u22121250 \u03bcm, exploiting data from PACS and SPIRE (PEP; HerMES), as well as Spitzer, SCUBA, AzTEC and MAMBO. We also explore the properties of an L_(IR)-matched sample, designed to reveal evolution of q_(IR) with redshift, spanning log L_(IR) = 11\u201312 L_\u2299 and z = 0\u22122, by stacking into the radio and far-IR images. For 1.4-GHz-selected galaxies in GOODS-N, we see tentative evidence of a break in the flux ratio, q_(IR), at L_(1.4 GHz) ~ 10^(22.7) WHz^(\u22121) where active galactic nuclei (AGN) are starting to dominate the radio power density, and of weaker correlations with redshift and T_d. From our 250-\u03bcm-selected sample we identify a small number of far-IR-bright outliers, and see trends of q_(IR) with L_(1.4 GHz), L_(IR), T_d and redshift, noting that some of these are inter-related. For our L_(IR-)matched sample, there is no evidence that q_(IR) changes significantly as we move back into the epoch of galaxy formation: we find q_(IR) \u221d (1+z)^\u03b3, where \u03b3 = \u22120.04 \u00b1 0.03 at z = 0 \u2212 2; however, discounting the least reliable data at z < 0.5 we find \u03b3 = \u22120.26 \u00b1 0.07, modest evolution which may be related to the radio background seen by ARCADE 2, perhaps driven by <10-\u03bcJy radio activity amongst ordinary star-forming galaxies at z > 1.", "date": "2010-07", "date_type": "published", "publication": "Astronomy and Astrophysics", "volume": "518", "publisher": "EDP Sciences", "pagerange": "Art.

", "abstract": "We present high spatial resolution (0.4 arcsec, \u22433.5 kpc) Plateau de Bure Interferometer interferometric data on three ultraluminous infrared galaxies (ULIRGs) at z ~ 2: two submillimetre galaxies (SMGs) and one submillimetre faint star-forming radio galaxy. The three galaxies have been robustly detected in CO rotational transitions, either ^(12)CO (J = 4\u21923) or ^(12)CO (J = 3\u21922), allowing their sizes and gas masses to be accurately constrained. These are the highest spatial resolution observations observed to date (by a factor of ~ 2) for intermediate-excitation CO emission in z ~ 2 ULIRGs. The galaxies appear extended over several resolution elements, having a mean radius of 3.7 kpc. High-resolution (0.3 arcsec) combined Multi-Element Radio-Linked Interferometer Network-Very Large Array observations of their radio continua allow an analysis of the star formation behaviour of these galaxies, on comparable spatial scales to those of the CO observations. This 'matched beam' approach sheds light on the spatial distribution of both molecular gas and star formation, and we can therefore calculate accurate star formation rates and gas surface densities: this allows us to place the three systems in the context of a Kennicutt\u2013Schmidt (KS)-style star formation law. We find a difference in size between the CO and radio emission regions, and as such we suggest that using the spatial extent of the CO emission region to estimate the surface density of star formation may lead to error. This size difference also causes the star formation efficiencies within systems to vary by up to a factor of 5. We also find, with our new accurate sizes, that SMGs lie significantly above the KS relation, indicating that stars are formed more efficiently in these extreme systems than in other high- z star-forming galaxies.", "date": "2010-06-11", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "405", "number": "1", "publisher": "Royal Astronomical Society", "pagerange": "219-233", "id_number": "CaltechAUTHORS:20100629-092653200", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20100629-092653200", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Institut national des sciences de l'Univers (INSU)" }, { "agency": "Max-Planck-Gesellschaft" }, { "agency": "Instituto Geografico Nacional (IGN)" }, { "agency": "Science and Technology Facilities Council (STFC)" }, { "agency": "Gates-Cambridge Trust" }, { "agency": "Centre National de la Recherche Scientifique (CNRS)" } ] }, "local_group": { "items": [ { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" } ] }, "doi": "10.1111/j.1365-2966.20", "primary_object": { "basename": "Bothwell2010p10433Mon_Not_R_Astron_Soc.pdf", "url": "https://authors.library.caltech.edu/records/smz6s-jb861/files/Bothwell2010p10433Mon_Not_R_Astron_Soc.pdf" }, "resource_type": "article", "pub_year": "2010", "author_list": "Bothwell, M.

", "abstract": "We present a quantitative morphological analysis using Hubble Space Telescope Near Infrared\nCamera and Multi-Object SpectrometerH160-band imaging and Advanced Camera for Surveys\nI_(775)-band imaging of 25 spectroscopically confirmed submillimetre galaxies (SMGs) which\nhave redshifts between z = 0.7 and 3.4 (z = 2.1). Our analysis also employs a comparison\nsample of more typical star-forming galaxies at similar redshifts (such as Lyman-break\nGalaxies) which have lower far-infrared luminosities. This is the first large-scale study of the\nmorphologies of SMGs in the near-infrared at ~0.1 arcsec resolution (\u227e1 kpc). We find that\nthe half-light radii of the SMGs (r_h = 2.3 \u00b1 0.3 and 2.8 \u00b1 0.4 kpc in the observed I and H\nbands, respectively) and asymmetries are not statistically distinct from the comparison sample\nof star-forming galaxies. However, we demonstrate that the SMG morphologies differ more\nbetween the rest-frame UV and optical bands than typical star-forming galaxies and interpret\nthis as evidence for structured dust obscuration. We show that the composite observed H-band\nlight profile of SMGs is better fitted with a high Sersic index (n ~ 2) than with an exponential\ndisc suggesting the stellar structure of SMGs is best described by a spheroid/elliptical galaxy\nlight distribution. We also compare the sizes and stellar masses of SMGs to local and highredshift\npopulations and find that the SMGs have stellar densities which are comparable to\n(or slightly larger than) local early-type galaxies and comparable to luminous, red and dense\ngalaxies at z ~ 1.5 which have been proposed as direct SMG descendants, although the SMG\nstellar masses and sizes are systematically larger. Overall, our results suggest that the physical\nprocesses occurring within the galaxies are too complex to be simply characterized by the\nrest-frame UV/optical morphologies which appear to be essentially decoupled from all other\nobservables, such as bolometric luminosity, stellar or dynamical mass.", "date": "2010-06", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "405", "number": "1", "publisher": "Royal Astronomical Society", "pagerange": "234-244", "id_number": "CaltechAUTHORS:20100628-085611076", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20100628-085611076", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "9174" }, { "agency": "NASA", "grant_number": "9856" }, { "agency": "Science and Technology Facilities Council (STFC)" }, { "agency": "NSF", "grant_number": "AST-0205937" }, { "agency": "Alfred P.

", "abstract": "Spitzer spectroscopy has revealed that \u224380% of submm galaxies (SMGs) are starburst (SB)-dominated in the mid-infrared. Here we focus on the remaining \u224320% that show signs of harboring powerful active galactic nuclei (AGNs). We have obtained Spitzer-InfraRed Spectrograph spectroscopy of a sample of eight SMGs that are candidates for harboring powerful AGNs on the basis of IRAC color selection (S_(8 \u03bcm)/S_(4.5 \u03bcm) > 2, i.e., likely power-law mid-infrared spectral energy distributions). SMGs with an AGN dominating (\u227350%) their mid-infrared emission could represent the \"missing link\" sources in an evolutionary sequence involving a major merger. First of all, we detect polycyclic aromatic hydrocarbon (PAH) features in all of the SMGs, indicating redshifts from 2.5 to 3.4, demonstrating the power of the mid-infrared to determine redshifts for these optically faint dusty galaxies. Second, we see signs of both star formation (from the PAH features) and AGN activity (from continuum emission) in our sample: 62% of the sample are AGN-dominated in the mid-infrared with a median AGN content of 56%, compared with <30% on average for typical SMGs, revealing that our IRAC color selection has successfully singled out sources with proportionately more AGN emission than typical SB-dominated SMGs. However, we find that only about 10% of these AGNs dominate the bolometric emission of the SMG when the results are extrapolated to longer infrared wavelengths, implying that AGNs are not a significant power source to the SMG population overall, even when there is evidence in the mid-infrared for substantial AGN activity. When existing samples of mid-infrared AGN-dominated SMGs are considered, we find that S_(8 \u03bcm)/S_(4.5 \u03bcm) > 1.65 works well at selecting mid-infrared energetically dominant AGNs in SMGs, implying a duty cycle of ~15% if all SMGs go through a subsequent mid-infrared AGN-dominated phase in the proposed evolutionary sequence.", "date": "2010-04-10", "date_type": "published", "publication": "Astrophysical Journal", "volume": "713", "number": "1", "publisher": "American Astronomical Society", "pagerange": "503-519", "id_number": "CaltechAUTHORS:20100415-110421934", "issn": "0004-637X", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20100415-110421934", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA/JPL/Caltech" }, { "agency": "Science and Technology Facilities Council (STFC)" }, { "agency": "NASA Spitzer Fellowship" }, { "agency": "NSF Astronomy and Astrophysics Fellowship", "grant_number": "AST-0802399" }, { "agency": "Royal Society" }, { "agency": "Leverhulme Trust" } ] }, "local_group": { "items": [ { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" } ] }, "doi": "10.1088/0004-637X/713/1/503", "primary_object": { "basename": "Coppin2010p7481Astrophys_J.pdf", "url": "https://authors.library.caltech.edu/records/38b9j-72a89/files/Coppin2010p7481Astrophys_J.pdf" }, "resource_type": "article", "pub_year": "2010", "author_list": "Coppin, K.; Pope, A.; et el." }, { "id": "https://authors.library.caltech.eduhttps://authors.library.caltech.edu/records/r530c-e2250", "eprint_id": 17690, "eprint_status": "archive", "datestamp": "2023-08-19 01:37:59", "lastmod": "2023-10-20 00:09:17", "type": "article", "metadata_visibility": "show", "creators": { "items": [ { "id": "Blain-A-W", "name": { "family": "Blain", "given": "Andrew" }, "orcid": "0000-0001-7489-5167" } ] }, "title": "Astrophysics: Less greedy galaxies gulp gas", "ispublished": "pub", "full_text_status": "restricted", "note": "\u00a9 2010 Macmillan Publishers Limited. \n\nPublished online 10 February 2010.", "abstract": "The cool molecular gas from which stars form has been detected in relatively ordinary faraway galaxies.

", "abstract": "We identify eight z > 1 radio sources undetected at 850 \u03bcm but robustly detected at 70 \u03bcm, confirming that they represent ultraluminous infrared galaxies (ULIRGs) with hotter dust temperatures (\u3008T_d\u3009= 52 \u00b1 10 K) than submillimetre galaxies (SMGs) at similar luminosities and redshifts. These galaxies share many properties with SMGs: ultraviolet spectra consistent with starbursts, high stellar masses and radio luminosities. We can attribute their radio emission to star formation since high-resolution Multi-Element Radio Linked Interferometer Network (MERLIN) radio maps show extended emission regions (with characteristic radii of 2\u20133 kpc), which are unlikely to be generated by active galactic nucleus (AGN) activity. These observations provide the first direct confirmation of hot, dusty ULIRGs which are missed by current submillimetre surveys. They have significant implications for future observations from the Herschel Space Observatory and Submillimetre Common-User Bolometer Array 2 (SCUBA2), which will select high-redshift luminous galaxies with less selection biases.", "date": "2009-10-11", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "399", "number": "1", "publisher": "Royal Astronomical Society", "pagerange": "121-128", "id_number": "CaltechAUTHORS:20091111-144225085", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20091111-144225085", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "University of Manchester" }, { "agency": "National Radio Astronomy Observatory" }, { "agency": "NSF" }, { "agency": "Associated Universities, Inc." }, { "agency": "Gates-Cambridge Trust" }, { "agency": "Science and Technology Facilities Council (STFC)" } ] }, "doi": "10.1111/j.1365-2966.2009.15291.x", "primary_object": { "basename": "Casey2009p6265Mon_Not_R_Astron_Soc.pdf", "url": "https://authors.library.caltech.edu/records/8rmae-p9q05/files/Casey2009p6265Mon_Not_R_Astron_Soc.pdf" }, "resource_type": "article", "pub_year": "2009", "author_list": "Casey, C.

", "abstract": "The Chandra COSMOS Survey (C-COSMOS) is a large, 1.8 Ms, Chandra program that has imaged the central 0.5 deg^2 of the COSMOS field (centered at 10 ^h , +02 ^o ) with an effective exposure of ~160 ks, and an outer 0.4 deg^2 area with an effective exposure of ~80 ks. The limiting source detection depths are 1.9 \u00d7 10^(\u201316) erg cm^(\u20132) s^(\u20131) in the soft (0.5-2 keV) band, 7.3 \u00d7 10^(\u201316) erg cm^(\u20132) s^(\u20131) in the hard (2-10 keV) band, and 5.7 \u00d7 10^(\u201316) erg cm^(\u20132) s^(\u20131) in the full (0.5-10 keV) band. Here we describe the strategy, design, and execution of the C-COSMOS survey, and present the catalog of 1761 point sources detected at a probability of being spurious of <2 \u00d7 10^(\u20135) (1655 in the full, 1340 in the soft, and 1017 in the hard bands). By using a grid of 36 heavily (~50%) overlapping pointing positions with the ACIS-I imager, a remarkably uniform (\u00b112%) exposure across the inner 0.5 deg^2 field was obtained, leading to a sharply defined lower flux limit. The widely different point-spread functions obtained in each exposure at each point in the field required a novel source detection method, because of the overlapping tiling strategy, which is described in a companion paper. This method produced reliable sources down to a 7-12 counts, as verified by the resulting logN-logS curve, with subarcsecond positions, enabling optical and infrared identifications of virtually all sources, as reported in a second companion paper.

", "abstract": "We present the results of a 400 ks Chandra survey of 29 extended Ly\u03b1 emitting nebulae (Ly\u03b1 Blobs, LABs) in the z = 3.09 protocluster in the SS A22 field. We detect luminous X-ray counterparts in five LABs, implying a large fraction of active galactic nuclei (AGN) in LABs,f_(AGN) = 17^(+12)_( 7)% down to L _(2-32 keV) ~ 10^(44) erg s^(\u20131). All of the AGN appear to be heavily obscured, with spectral indices implying obscuring column densities of N_ H > 10^(23) cm^(\u20132). The AGN fraction should be considered a lower limit, since several more LABs not detected with Chandra show AGN signatures in their mid-infrared (mid-IR) emission. We show that the UV luminosities of the AGN are easily capable of powering the extended Ly\u03b1 emission via photoionization alone. When combined with the UV flux from a starburst component, and energy deposited by mechanical feedback, we demonstrate that \"heating\" by a central source, rather than gravitational cooling is the most likely power source of LABs. We argue that all LABs could be powered in this manner, but that the luminous host galaxies are often just below the sensitivity limits of current instrumentation, or are heavily obscured. No individual LABs show evidence for extended X-ray emission, and a stack equivalent to a \u2273 9 Ms exposure of an average LAB also yields no statistical detection of a diffuse X-ray component. The resulting diffuse X-ray/Ly\u03b1 luminosity limit implies there is no hot (T\u227310^7 K) gas component in these halos, and also rules out inverse Compton scattering of cosmic microwave background photons, or local far-IR photons, as a viable power source for LABs.", "date": "2009-07-20", "date_type": "published", "publication": "Astrophysical Journal", "volume": "700", "number": "1", "publisher": "American Astronomical Society", "pagerange": "1-9", "id_number": "CaltechAUTHORS:20090827-135317395", "issn": "0004-637X", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20090827-135317395", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Science and Technology Facilities Council (STFC)" }, { "agency": "Royal Society" }, { "agency": "Leverhulme Trust" }, { "agency": "NASA", "grant_number": "G07-8138C" } ] }, "doi": "10.1088/0004-637X/700/1/1", "primary_object": { "basename": "Geach2009p5110Astrophys_J.pdf", "url": "https://authors.library.caltech.edu/records/hzkwn-waf68/files/Geach2009p5110Astrophys_J.pdf" }, "resource_type": "article", "pub_year": "2009", "author_list": "Geach, J.

", "abstract": "We present Spitzer-IRAC and MIPS mid-IR observations of a sample of 73 radio-detected submillimeter-selected galaxies (SMGs) with spectroscopic redshifts, the largest such sample published to date. From our data, we find that IRAC colors of SMGs are much more uniform as compared with rest-frame UV and optical colors, and z>1.5 SMGs tend to be redder in their mid-IR colors than both field galaxies and lower-z SMGs. However, the IRAC colors of the SMGs overlap those of field galaxies sufficiently that color-magnitude and color-color selection criteria suggested in the literature to identify SMG counterparts produce ambiguous counterparts within an 8\" radius in 20%-35% of cases. We use a rest-frame J\u2013H versus H\u2013K color-color diagram and a S _(24)/S_(8.0) versus S_(8.0)/S_(4.5) color-color diagram to determine that 13%-19% of our sample are likely to contain active galactic nuclei which dominate their mid-IR emission. We observe in the rest-frame JHK colors of our sample that the rest-frame near-IR emission of SMGs does not resemble that of the compact nuclear starburst observed in local ultraluminous IR galaxies and is consistent with more widely distributed star formation. We take advantage of the fact that many high-z galaxy populations selected at different wavelengths are detected by Spitzer to carry out a brief comparison of mid-IR properties of SMGs to UV-selected high-z galaxies, 24 \u03bcm-selected galaxies, and high-z radio galaxies, and find that SMGs have mid-IR fluxes and colors which are consistent with being more massive and more reddened than UV-selected galaxies, while the IRAC colors of SMGs are most similar to powerful high-z radio galaxies.", "date": "2009-07-10", "date_type": "published", "publication": "Astrophysical Journal", "volume": "699", "number": "2", "publisher": "American Astronomical Society", "pagerange": "1610-1632", "id_number": "CaltechAUTHORS:20090818-085135602", "issn": "0004-637X", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20090818-085135602", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Royal Society" }, { "agency": "NASA/JPL/Caltech" } ] }, "local_group": { "items": [ { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" } ] }, "doi": "10.1088/0004-637X/699/2/1610", "primary_object": { "basename": "Hainline2009p4719Astrophys_J.pdf", "url": "https://authors.library.caltech.edu/records/9zqn7-ct493/files/Hainline2009p4719Astrophys_J.pdf" }, "resource_type": "article", "pub_year": "2009", "author_list": "Hainline, Laura J.; Blain, A.

", "abstract": "We used the Spitzer Infrared Spectrograph (IRS) to study the mid-IR properties and investigate the energetics of 24 Submillimeter Galaxies (SMGs). This is the largest sample of SMGs observed with Spitzer IRS and covers the full extent of properties of the radio-identified population of SMGs in the redshift range of z ~ 0.65-3.2. We observe broad emission features from polycyclic aromatic hydrocarbons in more than 80% of our sample. We find that the median mid-IR spectrum is well described by a starburst component with an additional power law, F_\u03bd ~ \u03bd^(\u20132), likely representing a <32% contribution from an active galactic nucleus to the bolometric luminosity. Our results thus confirm that starburst activity dominates the bolometric luminosity in SMGs. We find that SMGs show weaker silicate absorption at ~9.7 \u03bcm than local ULIRGs. We also find stronger 6.2-\u03bcm PAH emission in SMGs (relative to the 7.7 \u03bcm PAH feature) than in local nuclear starbursts, which may be attributed to lower extinction by ice along the line of sight to SMGs. This suggests that the continuum and PAH emitting regions of SMGs are less obscured than in local starbursts and similarly luminous low-redshift ULIRGs. We interpret these results as evidence for a more extended distribution of cool and warm dust in SMGs compared to the more compact emitting regions in local ULIRGs and starbursts. Together these results suggest that SMGs are not simple high-redshift analogs of nuclear starbursts or local ULIRGs, but instead they appear to have star formation which resembles that seen in less-extreme star-forming environments at z~0 -suggesting their intense activity is distributed across a far larger region than the ~1 kpc nuclear bursts in local ULIRGs.", "date": "2009-07-01", "date_type": "published", "publication": "Astrophysical Journal", "volume": "699", "number": "1", "publisher": "American Astronomical Society", "pagerange": "667-685", "id_number": "CaltechAUTHORS:20090911-152535061", "issn": "0004-637X", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20090911-152535061", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NSF Astronomy and Astrophysics Fellowship", "grant_number": "AST-0702821" }, { "agency": "NASA/JPL/Caltech" }, { "agency": "Research Corporation" }, { "agency": "Alfred P.

", "abstract": "We present detailed observations of a z ~ 1.99 cluster of submillimeter galaxies (SMGs), discovered as the strongest redshift spike in our entire survey of ~100 SMGs across 800 arcmin^2. It is the largest blank-field SMG concentration currently known and has <0.01% chance of being drawn from the underlying selection function for SMGs. We have compared UV observations of galaxies at this redshift, where we find a much less dramatic overdensity, having an 11% chance of being drawn from its selection function. We use this z ~ 1.99 overdensity to compare the biasing of UV- and submillimeter-selected galaxies, and test whether SMGs could reside in less overdense environments, with their apparent clustering signal being dominated by highly active merger periods in modest mass structures. We discuss the probable mechanisms for the apparently different bias we see at the two wavelengths. This impressively active formation phase in a low-mass cluster is not something seen in simulations, although we propose a toy model using merger bias, which could account for the bias seen in the SMGs. While enhanced buildup of stellar mass appears characteristic of other high-z galaxy clusters, neither the UV galaxies nor SMGs in this structure exhibit larger stellar masses than their field galaxy counterparts (although the excess of SMGs in the structure represents a larger volume-averaged stellar mass than the field). Our findings have strong implications for future surveys of high-z galaxies at long wavelengths such as SCUBA2 and Herschel. We suggest that since these surveys will select galaxies during their episodes of peak starbursts, they could probe a much wider range of environments than just the progenitors of rich clusters, revealing more completely the key events and stages in galaxy formation and assembly.", "date": "2009-01-20", "date_type": "published", "publication": "Astrophysical Journal", "volume": "691", "number": "1", "publisher": "American Astronomical Society", "pagerange": "560-568", "id_number": "CaltechAUTHORS:20090416-133734002", "issn": "0004-637X", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20090416-133734002", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Natural Sciences and Engineering Research Council of Canada (NSERC)" }, { "agency": "Canadian Space Agency (CSA)" }, { "agency": "Royal Society" } ] }, "doi": "10.1088/0004-637X/691/1/560", "primary_object": { "basename": "Chapman2009p22110.10880004-637X6911560.pdf", "url": "https://authors.library.caltech.edu/records/7epyx-mev92/files/Chapman2009p22110.10880004-637X6911560.pdf" }, "resource_type": "article", "pub_year": "2009", "author_list": "Chapman, S.

", "abstract": "High-redshift, dust-obscured galaxies, selected to be luminous in the radio but relatively faint at 850 \u00b5m, appear to represent a different population from the ultraluminous submillimeter-bright population. They may be star-forming galaxies with hotter dust temperatures, or they may have lower far-infrared luminosities and larger contributions from obscured active galactic nuclei (AGNs). Here we present observations of three z ~ 2 examples of this population, which we term \"submillimeter-faint radio galaxies\" (SFRGs; RG J163655, RG J131236, and RG J123711) in\nCO(3-2) using the IRAM Plateau de Bure Interferometer to study their gas and dynamical properties.We estimate the\nmolecular gas mass in each of the three SFRGs (8.3 x 10^9, <5.6 x 10^9, and 15.4 ; 10^9 M\u2609, respectively) and, in the\ncase of RG J163655, a dynamical mass by measurement of the width of the CO(3-2) line (8 x 10^(10) csc^2i M\u2609). While\nthese gas masses are substantial, on average they are 4 times lower than submillimeter-selected galaxies (SMGs).\nRadio-inferred star formation rates (\u2039SFR_radio\u203a = 970 M\u2609 y^(-1)) suggest much higher star formation efficiencies than\nare found forSMGs and shorter gas depletion timescales (~11 Myr), much shorter than the time required to form their\ncurrent stellar masses (~160 Myr; ~ 10^(11) M\u2609). By contrast, star formation rates (SFRs) may be overestimated by\nfactors of a few, bringing the efficiencies in line with those typically measured for other ultraluminous star-forming\ngalaxies and suggesting that SFRGs are more like ultraviolet-selected (UV-selected) star-forming galaxies with\nenhanced radio emission. A tentative detection of RG J163655 at 350 \u00b5m suggests hotter dust temperatures, and thus\ngas-to-dust mass fractions, similar to the SMGs.", "date": "2008-12-20", "date_type": "published", "publication": "Astrophysical Journal", "volume": "689", "number": "2", "publisher": "American Astronomical Society", "pagerange": "889-896", "id_number": "CaltechAUTHORS:20090721-114831864", "issn": "0004-637X", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20090721-114831864", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Institut national des sciences de l'Univers (INSU)" }, { "agency": "Max Planck Gesellschaft" }, { "agency": "Instituto Geografico Nacional (IGN)" }, { "agency": "Canadian Space Agency (CSA)" }, { "agency": "Natural Sciences and Engineering Research Council of Canada (NSERC)" }, { "agency": "Royal Society" }, { "agency": "Science and Technology Facilities Council (STFC)" }, { "agency": "Centre National de la Recherche Scientifique (CNRS)" } ] }, "doi": "10.1086/592137", "primary_object": { "basename": "CHAapj08e.pdf", "url": "https://authors.library.caltech.edu/records/hes1q-vfp05/files/CHAapj08e.pdf" }, "resource_type": "article", "pub_year": "2008", "author_list": "Chapman, S.

", "abstract": "We present the optical-to-submillimetre spectral energy distributions (SEDs) for 33 radio and mid-infrared (mid-IR) identified submillimetre galaxies discovered via the SHADES 850-\u03bcm SCUBA imaging in the Subaru-XMM Deep Field (SXDF). Optical data for the sources come from the SXDF and mid- and far-IR fluxes from SWIRE. We obtain photometric redshift estimates for our sources using optical and IRAC 3.6- and 4.5-\u03bcm fluxes. We then fit SED templates to the longer wavelength data to determine the nature of the far-IR emission that dominates the bolometric luminosity of these sources. The IR template fits are also used to resolve ambiguous identifications and cases of redshift aliasing. The redshift distribution obtained broadly matches previous results for submillimetre sources and on the SHADES SXDF field. Our template fitting finds that active galactic nuclei, while present in about 10 per cent of our sources, do not contribute significantly to their bolometric luminosity. Dust heating by starbursts, with either Arp220 or M82 type SEDs, appears to be responsible for the luminosity in most sources (23/33 are fitted by Arp220 templates, 2/33 by the warmer M82 templates). 8/33 sources, in contrast, are fitted by a cooler cirrus dust template, suggesting that cold dust has a role in some of these highly luminous objects.

", "abstract": "We report subarcsecond resolution IRAM PdBI millimeter CO interferometry of four z ~ 2 submillimeter galaxies (SMGs), and sensitive CO(3-2) flux limits toward three z ~ 2 UV/optically selected star-forming galaxies. The new data reveal for the first time spatially resolved CO gas kinematics in the observed SMGs. Two of the SMGs show double or multiple morphologies, with complex, disturbed gas motions. The other two SMGs exhibit CO velocity gradients of ~500 km s^\u22121 across \u22640.2\" (1.6 kpc) diameter regions, suggesting that the star-forming gas is in compact, rotating disks. Our data provide compelling evidence that these SMGs represent extreme, short-lived \"maximum\" star-forming events in highly dissipative mergers of gas-rich galaxies. The resulting high-mass surface and volume densities of SMGs are similar to those of compact quiescent galaxies in the same redshift range and much higher than those in local spheroids. From the ratio of the comoving volume densities of SMGs and quiescent galaxies in the same mass and redshift ranges, and from the comparison of gas exhaustion timescales and stellar ages, we estimate that the SMG phase duration is about 100 Myr. Our analysis of SMGs and optically/UV selected high-redshift star-forming galaxies supports a \"universal\" Chabrier IMF as being valid over the star-forming history of these galaxies. We find that the ^(12)CO luminosity to total gas mass conversion factors at z ~ 2-3 are probably similar to those assumed at z ~ 0.

We employ the well-established virial black-hole mass estimator to \"weigh\"\nthe black holes of a sample of z \u2248 2 SMGs which exhibit broad H\u03b1 or H\u03b2 emission. We find that the average\nblack-hole mass and Eddington ratio (\u03b7 = Lbol/LEdd) of the lower-luminosity broad-line SMGs (LX \u2248 10^44 erg s^\u22121) are log(MBH/M\u0298) \u2248 8.0 and \u03b7 \u2248 0.2, respectively; by comparison, X-ray-luminous broad-line SMGs (LX \u2248 10^45 erg s^\u22121) have log(MBH/M\u0298) \u2248 8.4 and \u03b7 \u2248 0.6. The lower-luminosity broad-line SMGs lie in the same location of the LX\u2013LFIR plane as more typical SMGs hosting X-ray-obscured active galactic nuclei and may be intrinsically similar systems, but orientated so that the rest-frame optical nucleus is visible. Under this hypothesis, we conclude that SMGs host black holes with log(MBH/M\u0298) \u2248 7.8; we find supporting evidence from observations of local ultra-luminous infrared galaxies. Combining these black-hole mass constraints with measured host-galaxy masses, we find that the black holes in SMGs are \u22733 times smaller than those found in comparably massive normal galaxies in the local universe, albeit with considerable uncertainty, and \u227310 times smaller than those predicted for z \u2248 2 luminous quasars and radio galaxies. These results imply that the growth of the black hole lags that of the host galaxy in SMGs, in stark contrast with that previously suggested for radio galaxies and luminous quasars at z \u2248 2. On the basis of current host-galaxy mass constraints, we show that SMGs and their descendants cannot\nlie significantly above the locally defined MBH\u2013MGAL relationship. We argue that the black holes in the z \u2248 0 descendents of SMGs will have log(MBH/M\u0298) \u2248 8.6, indicating that they only need to grow by a factor of \u22486 by the present day. We show that this amount of black-hole growth can be achieved within current estimates for the submillimeter-bright lifetime of SMGs, provided that the black holes can grow at rates close to the Eddington limit.", "date": "2008-05", "date_type": "published", "publication": "Astronomical Journal", "volume": "135", "number": "5", "publisher": "American Astronomical Society", "pagerange": "1968-1981", "id_number": "CaltechAUTHORS:ALEaj08", "issn": "0004-6256", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:ALEaj08", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Royal Society" }, { "agency": "Science and Technology Facilities Council (STFC)" }, { "agency": "NASA", "grant_number": "NAG5-13035" }, { "agency": "NASA Chandra Fellowship" }, { "agency": "Alfred P.

However, the study of the dominant population of IR-luminous galaxies (10^(11) - 10^(12) Lsun at 1 < z < 3), requires observation of sources a at the 0.1 mJy level. We present the deepest spectra taken to date in the Long-Low module of the the Infrared Spectrometer (IRS) on the Spitzer Space Telescope. We targeted two faint (~0.15 mJy) sources in the Southern GOODS field at z = 1.09 and z = 2.69 as likely star-forming galaxies. Spectra of the lower redshift target were taken in 8-21 micron range (short-low first order and long-low second order), while the higher redshift target was observed from 21-37 microns (longlow first order). Observing times were 3 and 9 hours on-source for SL-1 and LL-2, respectively, and 12 hours for LL-1. We also present the spectra of two serendipitous sources. We detect strong PAH emission in four targets. We compare the spectra to those of local galaxies observed by the IRS. The z = 1.09 source appears to be a typical, star-formation dominated LIRG, while the z = 2.69 source is a composite source with strong star formation and a prominent AGN.

", "abstract": "Determining an accurate position for a submillimetre (submm) galaxy (SMG) is the crucial step that enables us to move from the basic properties of an SMG sample \u2013 source counts and 2D clustering \u2013 to an assessment of their detailed, multiwavelength properties, their contribution to the history of cosmic star formation and their links with present-day galaxy populations. In this paper, we identify robust radio and/or infrared (IR) counterparts, and hence accurate positions, for over two-thirds of the SCUBA HAlf-Degree Extragalactic Survey (SHADES) Source Catalogue, presenting optical, 24-\u03bcm and radio images of each SMG. Observed trends in identification rate have given no strong rationale for pruning the sample. Uncertainties in submm position are found to be consistent with theoretical expectations, with no evidence for significant additional sources of error. Employing the submm/radio redshift indicator, via a parametrization appropriate for radio-identified SMGs with spectroscopic redshifts, yields a median redshift of 2.8 for the radio-identified subset of SHADES, somewhat higher than the median spectroscopic redshift. We present a diagnostic colour\u2013colour plot, exploiting Spitzer photometry, in which we identify regions commensurate with SMGs at very high redshift. Finally, we find that significantly more SMGs have multiple robust counterparts than would be expected by chance, indicative of physical associations. These multiple systems are most common amongst the brightest SMGs and are typically separated by 2\u20136 arcsec, ~15\u201350/ sin i kpc at z\u223c 2, consistent with early bursts seen in merger simulations.", "date": "2007-09-01", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "380", "number": "1", "publisher": "Royal Astronomical Society", "pagerange": "199-228", "id_number": "CaltechAUTHORS:20100420-110615215", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20100420-110615215", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Alfred P.

We detect 15 sources at significance between 4 and 7 \u03c3, 11 of which are also detected at 1.4 GHz with the VLA with a flux density >24 \u03bcJy (3 \u03c3). We identify 12 more lower significance mm sources based on their association with faint radio sources. We present the multifrequency identifications of the MAMBO sources, including VLA radio flux densities, optical and near-infrared identifications, as well as the XMM-Newton X-ray detection for two of the mm sources. We compare radio and optical photometric redshifts and briefly describe the host galaxy morphologies. The colors of the identified optical counterparts suggest most of them to be high-redshift (z ~ 2-3) star-forming galaxies. At least three sources appear lensed by a foreground galaxy. We highlight some MAMBO sources that do not show obvious radio counterparts. These sources could be dusty starburst galaxies at redshifts >3.5.

", "abstract": "We present the first identification of large-scale structures (LSSs) at z < 1.1 in the Cosmic Evolution Survey (COSMOS). The structures are identified from adaptive smoothing of galaxy counts in the pseudo-3D space (\u03b1, \u03b4, z) using the COSMOS photometric redshift catalog. The technique is tested on a simulation including galaxies distributed in model clusters and a field galaxy population\u2014recovering structures on all scales from 1' to 20' without a priori assumptions for the structure size or density profile. The COSMOS photometric redshift catalog yields a sample of 1.5 \u00d7 10^5 galaxies with redshift accuracy, \u0394_z_(FWHM)/(1 + z) \u2264 0.1 at z < 1.1 down to I_(AB) \u2264 25 mag. Using this sample of galaxies, we identify 42 LSSs and clusters. Projected surface-density maps for the structures indicate multiple peaks and internal structure in many of the most massive LSSs. The stellar masses (determined from the galactic SEDs) for the LSSs range from M_* ~ 10^(11) up to ~3 \u00d7 10^(13) M_\u2609. Five LSSs have total stellar masses exceeding 10^13 M_\u2609. (Total masses including nonstellar baryons and dark matter are expected to be ~50-100 times greater.) The derived mass function for the LSSs is consistent (within the expected Poisson and cosmic variances) with those derived from optical and X-ray studies at lower redshift. To characterize structure evolution and for comparison with simulations, we compute a new statistic: the area filling factor as a function of the overdensity value compared to the mean at surface overdensity (f_A [\u03a3/\u03a3(overbar)(z)). The observationally determined f_A has less than 1% of the surface area (in each redshift slice) with overdensities exceeding 10:1, and evolution to higher overdensities is seen at later epochs (lower z); both characteristics are in good agreement with what we find using similar processing on the Millennium Simulation. Although similar variations in the filling factors as a function of overdensity and redshift are seen in the observations and simulations, we do find that the observed distributions reach higher overdensities than the simulation, perhaps indicating overmerging in the simulation. All of the LSSs show a dramatic preference for earlier SED type galaxies in the denser regions of the structures, independent of redshift. The SED types in the central 1 and 1-5 Mpc regions of each structure average about one SED type earlier than the mean type at the same redshift, corresponding to a stellar population age difference of ~2-4 Gyr at z = 0.3-1. We also investigate the evolution of key galactic properties\u2014mass, luminosity, SED, and star formation rate (SFR)\u2014with redshift and environmental density as derived from overdensities in the full pseudo-3D cube. Both the maturity of the stellar populations and the \"downsizing\" of star formation in galaxies vary strongly with redshift (epoch) and environment. For a very broad mass range (10^(10)-10^(12) M_\u2609), we find that galaxies in dense environments tend to be older; this is not just restricted to the most massive galaxies. And in low-density environments, the most massive galaxies appear to have also been formed very early (z > 2), compared to the lower mass galaxies there. Over the range z < 1.1, we do not see evolution in the mass of galaxies by more than a factor of ~2 separating active and inactive star-forming galaxy populations.", "date": "2007-09", "date_type": "published", "publication": "Astrophysical Journal Supplement Series", "volume": "172", "number": "1", "publisher": "American Astronomical Society", "pagerange": "150-181", "id_number": "CaltechAUTHORS:20100219-111725493", "issn": "0067-0049", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20100219-111725493", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "local_group": { "items": [ { "id": "COSMOS" }, { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" } ] }, "doi": "10.1086/516751", "primary_object": { "basename": "SCOapjss07c.pdf", "url": "https://authors.library.caltech.edu/records/vj16w-nt636/files/SCOapjss07c.pdf" }, "resource_type": "article", "pub_year": "2007", "author_list": "Scoville, N.; Aussel, H.; et el." }, { "id": "https://authors.library.caltech.eduhttps://authors.library.caltech.edu/records/rzhjp-de478", "eprint_id": 17715, "eprint_status": "archive", "datestamp": "2023-08-22 09:53:44", "lastmod": "2023-10-20 00:10:29", "type": "article", "metadata_visibility": "show", "creators": { "items": [ { "id": "Sanders-D-B", "name": { "family": "Sanders", "given": "D.

", "abstract": "The COSMOS Spitzer survey (S-COSMOS) is a Legacy program (Cycles 2+3) designed to carry out a uniform deep survey of the full 2 deg^2 COSMOS field in all seven Spitzer bands (3.6, 4.5, 5.6, 8.0, 24.0, 70.0, and 160.0 \u03bcm). This paper describes the survey parameters, mapping strategy, data reduction procedures, achieved sensitivities to date, and the complete data set for future reference. We show that the observed infrared backgrounds in the S-COSMOS field are within 10% of the predicted background levels. The fluctuations in the background at 24 \u03bcm have been measured and do not show any significant contribution from cirrus, as expected. In addition, we report on the number of asteroid detections in the low Galactic latitude COSMOS field. We use the Cycle 2 S-COSMOS data to determine preliminary number counts, and compare our results with those from previous Spitzer Legacy surveys (e.g., SWIRE, GOODS). The results from this \"first analysis\" confirm that the S-COSMOS survey will have sufficient sensitivity with IRAC to detect ~L^* disks and spheroids out to z \u2273 3, and with MIPS to detect ultraluminous starbursts and AGNs out to z ~ 3 at 24 \u03bcm and out to z ~ 1.5-2 at 70 and 160 \u03bcm.", "date": "2007-09", "date_type": "published", "publication": "Astrophysical Journal Supplement Series", "volume": "172", "number": "1", "publisher": "American Astronomical Society", "pagerange": "86-98", "id_number": "CaltechAUTHORS:20100310-103340276", "issn": "0067-0049", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20100310-103340276", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA/JPL", "grant_number": "1278386" }, { "agency": "NASA/JPL/Caltech", "grant_number": "1407" } ] }, "local_group": { "items": [ { "id": "COSMOS" }, { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" } ] }, "doi": "10.1086/517885", "primary_object": { "basename": "SANapjss07.pdf", "url": "https://authors.library.caltech.edu/records/rzhjp-de478/files/SANapjss07.pdf" }, "resource_type": "article", "pub_year": "2007", "author_list": "Sanders, D.

", "abstract": "Determining an accurate position for a submillimetre (submm) galaxy (SMG) is the crucial step that enables us to move from the basic properties of an SMG sample \u2013 source counts and 2D clustering \u2013 to an assessment of their detailed, multiwavelength properties, their contribution to the history of cosmic star formation and their links with present-day galaxy populations. In this paper, we identify robust radio and/or infrared (IR) counterparts, and hence accurate positions, for over two-thirds of the SCUBA HAlf-Degree Extragalactic Survey (SHADES) Source Catalogue, presenting optical, 24-\u03bcm and radio images of each SMG. Observed trends in identification rate have given no strong rationale for pruning the sample. Uncertainties in submm position are found to be consistent with theoretical expectations, with no evidence for significant additional sources of error. Employing the submm/radio redshift indicator, via a parametrization appropriate for radio-identified SMGs with spectroscopic redshifts, yields a median redshift of 2.8 for the radio-identified subset of SHADES, somewhat higher than the median spectroscopic redshift. We present a diagnostic colour\u2013colour plot, exploiting Spitzer photometry, in which we identify regions commensurate with SMGs at very high redshift. Finally, we find that significantly more SMGs have multiple robust counterparts than would be expected by chance, indicative of physical associations. These multiple systems are most common amongst the brightest SMGs and are typically separated by 2\u20136 arcsec, ~15-50/(sin i) kpc at z\u223c 2, consistent with early bursts seen in merger simulations.", "date": "2007-09", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "380", "number": "1", "publisher": "Royal Astronomical Society", "pagerange": "199-228", "id_number": "CaltechAUTHORS:20210309-104057357", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20210309-104057357", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Alfred P.

These include data taken on the Subaru 8.3 m telescope, the KPNO and CTIO 4 m telescopes, and the CFHT 3.6 m telescope. Special techniques are used to ensure that the relative photometric calibration is better than 1% across the field of view. The absolute photometric accuracy from standard-star measurements is found to be 6%. The absolute calibration is corrected using galaxy spectra, providing colors accurate to 2% or better. Stellar and galaxy colors and counts agree well with the expected values.

", "abstract": "We discuss color selection of rare objects in a wide-field multiband survey spanning from the optical to the mid-infrared. Simple color criteria simultaneously identify and distinguish two of the most sought after astrophysical sources: the coolest brown dwarfs and the most distant quasars. We present spectroscopically confirmed examples of each class identified in the IRAC Shallow Survey of the Bo\u00f6tes field of the NOAO Deep Wide-Field Survey. IRAC J142950.8+333011 is a T4.5 brown dwarf at a distance of approximately 30-40 pc, and IRAC J142738.5+331242 is a radio-loud quasar at redshift z = 6.12. Our selection criteria identify a total of four candidates over 8 deg^2 of the Bo\u00f6tes field. The other two candidates are both confirmed 5.5 < z < 6 quasars, previously reported by Cool et al. (2006). We discuss the implications of these discoveries and conclude that there are excellent prospects for extending such searches to cooler brown dwarfs and higher redshift quasars.", "date": "2007-07-01", "date_type": "published", "publication": "Astrophysical Journal", "volume": "663", "number": "1", "publisher": "American Astronomical Society", "pagerange": "677-685", "id_number": "CaltechAUTHORS:20100113-110457246", "issn": "0004-637X", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20100113-110457246", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA/JPL/Caltech" }, { "agency": "National Optical Astronomy Observatory (NOAO)" } ] }, "local_group": { "items": [ { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" } ] }, "doi": "10.1086/516833", "primary_object": { "basename": "STEapj07.pdf", "url": "https://authors.library.caltech.edu/records/11qq2-c5t78/files/STEapj07.pdf" }, "resource_type": "article", "pub_year": "2007", "author_list": "Stern, Daniel; Kirkpatrick, J.

", "abstract": "The study of the dominant population of high-redshift IR-luminous galaxies (10^(11)-10^(12) L_\u2609 at 1 < z < 3), requires observation of sources at the ~0.1 mJy level in the mid-IR. We present the deepest spectra taken to date with the Infrared Spectrograph (IRS) on the Spitzer Space Telescope. We targeted two faint (f_(24) ~ 0.15 mJy) sources in the Southern GOODS field at z = 1.09 and z = 2.69. Spectra of the lower redshift target were taken in the observed-frame 8-21 \u03bcm range, while the spectrum of the higher redshift target covered 21-37 \u03bcm. We also present the spectra of two secondary sources within the slit. We detect strong PAH emission in all four targets, and compare the spectra to those of local galaxies observed by the IRS. The z = 1.09 source appears to be a typical, star-formation-dominated IR-luminous galaxy, while the z = 2.69 source is a composite source with strong star formation and a prominent AGN. The IRAC colors of this source show no evidence of rest-frame near-IR stellar photospheric emission. We demonstrate that an AGN that contributes only a small (~10%) fraction of the bolometric luminosity can produce enough hot dust emission to overwhelm the near-IR photospheric emission from stars. Such sources would be excluded from photometric surveys that rely on the near-IR bump to identify starbursts, leading to an underestimate of the star formation rate density.", "date": "2007-04-20", "date_type": "published", "publication": "Astrophysical Journal", "volume": "659", "number": "2", "publisher": "American Astronomical Society", "pagerange": "941-949", "id_number": "CaltechAUTHORS:20091203-165711041", "issn": "0004-637X", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20091203-165711041", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "1407" }, { "agency": "NASA/JPL/Caltech" } ] }, "local_group": { "items": [ { "id": "Infrared-Processing-and-Analysis-Center-(IPAC)" } ] }, "doi": "10.1086/512802", "primary_object": { "basename": "TEPapj07.pdf", "url": "https://authors.library.caltech.edu/records/16r6k-8zd71/files/TEPapj07.pdf" }, "resource_type": "article", "pub_year": "2007", "author_list": "Teplitz, H.

", "abstract": "A significant population of distant sub-millimeter-selected galaxies\n(SMGs) with powerful dust continuum emission, which matches the luminosity\nof the brightest QSOs and exceeds that of most extreme local galaxies\ndetected by IRAS, has been known for almost a decade. The full range of powerful\nground- and space-based facilities have been used to investigate them, and a\ngood deal of information about their properties has been gathered. This meeting\naddresses some of the key questions for better understanding their properties.\nWhile continuum detection is relatively efficient, a spectrum is always required\nboth to determine a distance/luminosity, and to probe astrophysics: excitation\nconditions, total mass, mass distribution, and degree of dynamical relaxation.\nOnce a redshift is known, then the associated stellar mass can be found, and\nmore specialized spectrographs can be used to search for specific line diagnostics.\nThe first generation of submm surveys has yielded a combined sample of several\nhundred SMGs. Here we discuss the size and follow-up of future SMG samples\nthat will be compiled in much larger numbers by JCMT-SCUBA-2, Herschel,\nPlanck, LMT, ALMA, and a future large-aperture (25m-class) submm/far-IR\nwide-field ground-based telescope, CCAT, planned to operate at a Chilean site\neven better than ALMA's.

", "abstract": "We report the results of a systematic near-IR spectroscopic survey using the Subaru, VLT, and Keck Telescopes of a sample of high-redshift ULIRGs mainly composed of submillimeter-selected galaxies. Our observations span the rest-frame optical range containing nebular emission lines such as H\u03b2, [O III] \u03bb\u03bb4959, 5007, and [O II] \u03bb3727, which are essential for making robust diagnostics of the physical properties. Using the H\u03b1/H\u03b2 emission line ratios, we derive internal extinction estimates for these galaxies similar to those of local ULIRGs: A_V ~ 2.9 \u00b1 0.5. Correcting the H\u03b1 estimates of the star formation rate for dust extinction results in rates that are consistent with those estimated from the far-IR luminosity. The majority (>60%) of our sample show spectral features characteristic of AGNs (although this partially reflects an observational bias), with ~65% exhibiting broad Balmer emission lines. A proportion of these sources show relatively low [O III] \u03bb5007/H\u03b2 line ratios, which are similar to those of narrow-line Seyfert 1 galaxies, suggesting low-mass black holes that are rapidly growing. In the subsample of our survey with both [O III] \u03bb5007 and hard X-ray coverage, at least ~60% show an excess of [O III] \u03bb5007 emission, by a factor of 5-10, relative to the hard X-ray luminosity compared to the correlation between these two properties seen in Seyfert galaxies and QSOs locally. From our spectral diagnostics, we propose that the strong [O III] \u03bb5007 emission in these galaxies arises from shocks in dense gaseous regions. Due to sensitivity and resolution limits, our sample is biased to strong-line emitters and hence our results do not yet provide a complete view of the physical properties of the whole high-redshift ULIRG population.", "date": "2006-11-10", "date_type": "published", "publication": "Astrophysical Journal", "volume": "651", "number": "2", "publisher": "American Astronomical Society", "pagerange": "713-727", "id_number": "CaltechAUTHORS:20110211-113035552", "issn": "0004-637X", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20110211-113035552", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Royal Society" }, { "agency": "Particle Physics and Astronomy Research Council (PPARC)" }, { "agency": "W.

For both sources we have obtained spectra with channel-to-channel rms noise of \u03c3 \u2264 0.5 mJy, resulting in velocity-integrated line fluxes ~< 0.1 Jy km s^(-1), although we do not detect either source. Such sensitive observations, aided by gravitational lensing of the sources, permit us to put upper limits of L'HCN ~< 2 \u00d7 10^(10) K km s^(-1) pc^2 on the intrinsic HCN(1-0) line luminosities of the two SMGs. The far-infrared (FIR) luminosities for all three SMGs with sensitive HCN(1-0) observations to date are found to be consistent with the tight FIR-HCN luminosity correlation observed in Galactic molecular clouds, quiescent spiral galaxies, and (ultra) luminous infrared galaxies in the local universe. Thus, the observed HCN luminosities remain in accordance with what is expected from the universal star formation efficiency per dense molecular gas mass implied by the aforementioned correlation, and more sensitive observations with today's large-aperture radio telescopes hold the promise of detecting HCN(1-0) emission in similar objects in the distant universe.", "date": "2006-11", "date_type": "published", "publication": "Astronomical Journal", "volume": "132", "number": "5", "publisher": "American Astronomical Society", "pagerange": "1938-1943", "id_number": "CaltechAUTHORS:GREaj06", "issn": "0004-6256", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:GREaj06", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "National Radio Astronomy Observatory" }, { "agency": "Alfred P.

", "abstract": "We present maps, source catalogue and number counts of the largest, most complete and unbiased extragalactic submillimetre survey: the 850-\u03bcm SCUBA Half-Degree Extragalactic Survey (SHADES). Using the Submillimetre Common-User Bolometer Array (SCUBA) on the James Clerk Maxwell Telescope (JCMT), SHADES mapped two separate regions of sky: the Subaru/XMM\u2013Newton Deep Field (SXDF) and the Lockman Hole East (LH). Encompassing 93 per cent of the overall acquired data (i.e. data taken up to 2004 February 1), these SCUBA maps cover 720 arcmin\u00b2 with a rms noise level of about 2 mJy and have uncovered >100 submillimetre galaxies. In order to ensure the utmost robustness of the resulting source catalogue, data reduction was independently carried out by four subgroups within the SHADES team, providing an unprecedented degree of reliability with respect to other SCUBA catalogues available from the literature. Individual source lists from the four groups were combined to produce a robust 120-object SHADES catalogue; an invaluable resource for follow-up campaigns aiming to study the properties of a complete and consistent sample of submillimetre galaxies. For the first time, we present deboosted flux densities for each submillimetre galaxy found in a large survey. Extensive simulations and tests were performed separately by each group in order to confirm the robustness of the source candidates and to evaluate the effects of false detections, completeness and flux density boosting. Corrections for these effects were then applied to the data to derive the submillimetre galaxy source counts. SHADES has a high enough number of detected sources that meaningful differential counts can be estimated, unlike most submillimetre surveys which have to consider integral counts. We present differential and integral source number counts and find that the differential counts are better fit with a broken power law or a Schechter function than with a single power law; the SHADES data alone significantly show that a break is required at several mJy, although the precise position of the break is not well constrained. We also find that a 850-\u03bcm survey complete down to 2 mJy would resolve 20\u201330 per cent of the far-infrared background into point sources.", "date": "2006-11", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "372", "number": "4", "publisher": "Royal Astronomical Society", "pagerange": "1621-1652", "id_number": "CaltechAUTHORS:20110228-075655571", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20110228-075655571", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Natural Sciences and Engineering Research Council of Canada (NSERC)" }, { "agency": "Particle Physics and Astronomy Research Council (PPARC)" }, { "agency": "Consejo Nacional de Ciencia y Tecnolog\u00eda (CONACyT)", "grant_number": "39548-F" }, { "agency": "Consejo Nacional de Ciencia y Tecnolog\u00eda (CONACyT)", "grant_number": "39953-F" } ] }, "doi": "10.1111/j.1365-2966.2006.10961.x", "primary_object": { "basename": "0609039.pdf", "url": "https://authors.library.caltech.edu/records/5bxxj-stb09/files/0609039.pdf" }, "related_objects": [ { "basename": "COPmnras06.pdf", "url": "https://authors.library.caltech.edu/records/5bxxj-stb09/files/COPmnras06.pdf" } ], "resource_type": "article", "pub_year": "2006", "author_list": "Coppin, K.

We identify the line in the spectrum of SMM J13120+4242 as a broad emission feature at z = 3.408, with \u0394V_(FWHM) = 1040 \u00b1 190 km s^(-1). If the observed CO (1\u21920) line profile arises from a single object and not several merging objects, then the CO (4 \u2192 3)/CO (1 \u2192 0) brightness temperature ratio of ~0.26 suggests n(H_2) > (3-10) \u00d7 10^2 cm^(-3) and the presence of subthermally excited gas. The integrated line flux implies a cold molecular gas mass M(H_2) = 1.6 \u00d7 10^(11) M_\u2609, comparable to the dynamical mass estimate and 4 times larger than the H_2 mass predicted from the CO (4\u21923) line, assuming a brightness temperature ratio of 1.0. While our observations confirm that this submillimeter galaxy is massive and gas-rich, they also suggest that extrapolating gas masses from J_(upper) \u2265 3 transitions of CO leads to considerable uncertainties.

", "abstract": "We present 350 \u03bcm observations of 15 Chapman et al. submillimeter galaxies (SMGs) with radio counterparts and optical redshifts. We detect 12 and obtain sensitive upper limits for three, providing direct, precise measurements of their far-infrared luminosities and characteristic dust temperatures. With these, we verify the linear radio-far-infrared correlation at redshifts of z ~ 1-3 and luminosities of 10^(11)-10^(13) L_\u2609, with a power-law index of 1.02 \u00b1 0.12 and rms scatter of 0.12 dex. However, either the correlation constant q or the dust emissivity index \u03b2 is lower than measured locally. The best-fitting q \u22432.14 is consistent with SMGs being predominantly starbust galaxies, without significant AGN contribution, at far-infrared wavelengths. Gas-to-dust mass ratios are estimated at 54^(+14)_(-11)(\u03ba_(850\u03bcm)/0.15 m^2 kg^(-1)), depending on the absoption efficiency \u03ba_\u03bd, with intrinsic dispersion \u224340% around the mean value. Dust temperatures consistent with 34.6 \u00b1 3 K (1.5/\u03b2)^(0.71), at z ~ 1.5-3.5, suggest that far-infrared photometric redshifts may be viable, and perhaps accurate to 10% \u2272 dz/(1 + z), for up to 80% of the SMG population in this range, if the above temperature characterizes the full range of SMGs. However, observed temperature evolution of T_d \u221d (1 + z) is also plausible and could result from selection effects. From the observed luminosity-temperature (L-T) relation, L \u221d T^(2.82\u00b10.29)_(obs), we derive scaling relations for dust mass versus dust temperature, and we identify expressions to interrelate the observed quantities. These suggest that measurements at a single wavelength, in the far-infrared, submillimeter, or radio wave bands, might constrain dust temperatures and far-infrared luminosities for most SMGs with redshifts at z ~ 0.5-4.", "date": "2006-10-20", "date_type": "published", "publication": "Astrophysical Journal", "volume": "650", "number": "2", "publisher": "American Astronomical Society", "pagerange": "592-603", "id_number": "CaltechAUTHORS:20110602-110110694", "issn": "0004-637X", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20110602-110110694", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NSF" } ] }, "doi": "10.1086/506341", "primary_object": { "basename": "KOVapj06.pdf", "url": "https://authors.library.caltech.edu/records/7swht-p2q48/files/KOVapj06.pdf" }, "resource_type": "article", "pub_year": "2006", "author_list": "Kov\u00e1cs, A.; Chapman, S.

", "abstract": "We present two-dimensional spectroscopy covering the rest-frame wavelengths of strong optical emission lines in six luminous submillimetre galaxies (SMGs) at z= 1.3\u20132.5. Using this near-infrared integral field spectroscopy together with Hubble Space Telescope ACS and NICMOS imaging, we map the dynamics and morphologies of these systems on scales from 4\u201311 kpc. Four of the systems show multiple components in their spatially resolved spectra with average velocity offsets of ~180 km s^(\u22121) across 8 kpc in projection. From the ensemble properties of eight galaxies, from our survey and the literature, we estimate the typical dynamical masses of bright SMGs as 5 \u00b1 3 \u00d7 10^(11) M_\u2299. This is similar to recent estimates of their stellar masses \u2013 suggesting that the dynamics of the central regions of these galaxies are baryon dominated, with a substantial fraction of those baryons in stars by the epoch of observation. Combining our dynamical mass estimates with stellar luminosities for this population, we investigate whether SMGs can evolve on to the Faber\u2013Jackson (FJ) relation for local ellipticals. Adopting a typical lifetime of \u03c4_(burst) ~300 Myr for the submillimetre-luminous phase \u2013 using the latest estimates of gas masses, star formation rates and active galactic nucleus contribution to the bolometric luminosities \u2013 we find that the stellar populations of SMGs should fade to place them on the FJ relation, at M_K ~ \u221225.1. Furthermore, using the same starburst lifetime we correct the observed space density of SMGs for the duty cycle to derive a volume density of the progenitors of ~1 \u00d7 10^(\u22124) Mpc^(\u22123). This is consistent with the space density of local luminous early-type galaxies with M_K ~ \u221225.1, indicating that SMGs can evolve on to the scaling relations observed for local early-type galaxies, and the observed population at z ~ 2 is then sufficient to account for the formation of the whole population of \u22733 L^*_K ellipticals seen at z ~ 0.", "date": "2006-09", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "371", "number": "1", "publisher": "Royal Astronomical Society", "pagerange": "465-476", "id_number": "CaltechAUTHORS:20110721-094851831", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20110721-094851831", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Particle Physics and Astronomy Research Council (PPARC)" }, { "agency": "Royal Society" }, { "agency": "Research Corporation" }, { "agency": "Alfred P.

", "abstract": "We present optical and near-infrared integral field spectroscopy of the SCUBA galaxy SMMJ163650.43+405734.5 (ELAIS N2 850.4) at z = 2.385. We combine Ly\u03b1 and H\u03b1 emission line maps and velocity structure with high-resolution HST ACS and NICMOS imaging to probe the complex dynamics of this vigorous starburst galaxy. The imaging data show a complex morphology, consisting of at least three components separated by \u223c1 arcsec (8 kpc) in projection. When combined with the H\u03b1 velocity field from UKIRT UIST IFU observations we identify two components whose redshifts are coincident with the systemic redshift, measured from previous CO observations, one of which shows signs of AGN activity. A third component is offset by 220 \u00b1 50 km s^(\u22121) from the systemic velocity. The total star-formation rate of the whole system (estimated from the narrow-line H\u03b1 and uncorrected for reddening) is 340 \u00b1 50 M_\u2299 yr^(\u22121). The Ly\u03b1 emission mapped by the GMOS IFU covers the complete galaxy and is offset by +270 \u00b1 40 km s\u22121 from the systemic velocity. This velocity offset is comparable to that seen in rest-frame UV-selected galaxies at similar redshifts and usually interpreted as a starburst-driven wind. The extended structure of the Ly\u03b1 emission suggests that this wind is not a nuclear phenomenon, but is instead a galactic-scale outflow. Our observations suggest that the vigorous activity in N2 850.4 is arising as a result of an interaction between at least two dynamically-distinct components, resulting in a strong starburst, a starburst-driven wind and actively-fuelled AGN activity. Whilst these observations are based on a single object, our results clearly show the power of combining optical and near-infrared integral field spectroscopy to probe the power sources, masses and metallicities of far-infrared luminous galaxies, as well as understanding the role of AGN- and starburst-driven feedback processes in these high-redshift systems.", "date": "2005-05-11", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "359", "number": "2", "publisher": "Royal Astronomical Society", "pagerange": "401-407", "id_number": "CaltechAUTHORS:20170409-065332465", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20170409-065332465", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Particle Physics and Astronomy Research Council (PPARC)" }, { "agency": "Royal Society" }, { "agency": "Euro 3D Research Training Network" }, { "agency": "NSF", "grant_number": "AST-0205937" }, { "agency": "Alfred P.

Optically luminous quasars host the most prodigious accreting black holes in the Universe, and can account for greater than or \u227330 per cent of the total cosmological black-hole growth. As typical quasars are not, however, undergoing intense star formation and already host massive black holes (> 10^8 M_\u2609, where M_\u2609 is the solar mass), there must have been an earlier pre-quasar phase when these black holes grew (mass range approx(10^6\u201310^8)M_\u2609. The likely signature of this earlier stage is simultaneous black-hole growth and star formation in distant (redshift z > 1; >8 billion light years away) luminous galaxies. Here we report ultra-deep X-ray observations of distant star-forming galaxies that are bright at submillimetre wavelengths. We find that the black holes in these galaxies are growing almost continuously throughout periods of intense star formation. This activity appears to be more tightly associated with these galaxies than any other coeval galaxy populations. We show that the black-hole growth from these galaxies is consistent with that expected for the pre-quasar phase.", "date": "2005-04-07", "date_type": "published", "publication": "Nature", "volume": "434", "number": "7034", "publisher": "Nature Publishing Group", "pagerange": "738-740", "id_number": "CaltechAUTHORS:20150325-143052004", "issn": "0028-0836", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20150325-143052004", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Royal Society" }, { "agency": "NASA" }, { "agency": "Particle Physics and Astronomy Research Council (PPARC)" } ] }, "doi": "10.1038/nature03473", "resource_type": "article", "pub_year": "2005", "author_list": "Alexander, D.

", "abstract": "Ultimately, after the Single Aperture Far-IR (SAFIR) telescope, astrophysicists will need a far-IR observatory that provides angular resolution comparable to that of the Hubble Space Telescope. At such resolution galaxies at high redshift, protostars, and nascent planetary systems will be resolved, and theoretical models for galaxy, star, and planet formation and evolution can be subjected to important observational tests. This paper updates information provided in a 2000 SPIE paper on the scientific motivation and design concepts for interferometric missions SPIRIT (the Space Infrared Interferometric Telescope) and SPECS (the Submillimeter Probe of the Evolution of Cosmic Structure).

", "abstract": "SAFIR is a large (10 m-class), cold (4-10 K) space telescope for wavelengths between 20 microns and 1 mm. It will provide sensitivity a factor of a hundred or more greater than that of Spitzer and Herschel, leveraging their capabilities and building on their scientific legacies. Covering this scientifically critical wavelength regime, it will complement the expected wavelength performance of the future flagship endeavors JWST and ALMA. This vision mission will probe the origin of stars and galaxies in the early universe, and explore the formation of solar systems around nearby young stars. Endorsed as a priority by the Decadal Study and successive OSS roadmaps, SAFIR represents a huge science need that is matched by promising and innovative technologies that will allow us to satisfy it. In exercising those technologies it will create the path for future infrared missions. This paper reviews the scientific goals of the mission and promising approaches for its architecture, and considers remaining technological hurdles.

Observations suggest that the AGN contribution to the luminosities of these submillimetre-selected galaxies is low; instead their luminosities are thought to be mainly due to strong episodes of star formation following merger events. Our current understanding of GRBs as the endpoints in the life of massive stars suggest that they will be located in such galaxies.We have observed a sample of well-located GRB host galaxies in the submillimetre. Comparing the results with the general submillimetre-selected galaxy population, we find that at low fluxes (S850 \u2264 4 mJy), the two agree well. However, there is a lack of bright GRB hosts in the submillimetre. This finding is reinforced when the results of other groups are included. Possible explanations are discussed.

", "abstract": "A significant fraction of the energy emitted in the early Universe came from very luminous galaxies that are largely hidden at optical wavelengths (because of interstellar dust grains); this energy now forms part of the cosmic background radiation at wavelengths near 1 mm (ref. 1). Some submillimetre (submm) galaxies have been resolved from the background radiation, but they have been difficult to study because of instrumental limitations. This has impeded the determination of their redshifts (z), which is a crucial element in understanding their nature and evolution. Here we report spectroscopic redshifts for ten submm galaxies that were identified using high-resolution radio observations. The median redshift for our sample is 2.4, with a quartile range of 1.9\u20132.8. This population therefore coexists with the peak activity of quasars, suggesting a close relationship between the growth of massive black holes and luminous dusty galaxies. The space density of submm galaxies at redshifts over 2 is about 1,000 times greater than that of similarly luminous galaxies in the present-day Universe, so they represent an important component of star formation at high redshifts.", "date": "2003-04-17", "date_type": "published", "publication": "Nature", "volume": "422", "number": "6933", "publisher": "Nature Publishing Group", "pagerange": "695-698", "id_number": "CaltechAUTHORS:20150326-090532312", "issn": "0028-0836", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20150326-090532312", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA" }, { "agency": "Royal Society" }, { "agency": "Leverhulme Trust" }, { "agency": "W.

", "abstract": "We discuss how gamma-ray burst (GRB) optical afterglows and multiwavelength observations of their host galaxies can be used to obtain information about the relative amounts of star formation happening in optical and submillimetre galaxies. That such an analysis will be possible follows from the currently favoured idea that GRBs are closely linked with high-mass star formation. Studying GRB host galaxies offers a method of finding low-luminosity submillimetre galaxies, which cannot be identified either in optical Lyman break surveys, because so much of their star formation is hidden by dust, or in submillimetre surveys, because their submillimetre fluxes are close to or below the confusion limit. Much of the star formation in the Universe could have occurred in such objects, so searching for them is an important exercise. From current observations, GRB host galaxies appear to be neither optically luminous Class-2 SCUBA galaxies like SMM J02399 \u2212 0136 or SMM J14011 + 0252, nor galaxies containing dense molecular cores like local ultraluminous infrared galaxies (ULIGs), but rather some intermediate kind of galaxy.

", "abstract": "Submillimetre- (submm-) wave observations have revealed a cosmologically significant population of high-redshift dust-enshrouded galaxies. The form of evolution inferred for this population can be reconciled easily with COBE FIRAS and DIRBE measurements of the cosmic background radiation (CBR) intensity at wavelengths longer than ~100 \u03bcm. At shorter wavelengths, however, the 60-\u03bcm CBR intensity reported by Finkbeiner, Davis & Schlegel is less easily accounted for. Lagache et al. have proposed that this excess CBR emission is a warm Galactic component, and the detection of the highest-energy \u03b3-rays from blazars limits the CBR intensity at these wavelengths, but here we investigate possible sources of this excess CBR emission, assuming that it has a genuine extragalactic origin. We propose and test three explanations, each involving additional populations of luminous, evolving galaxies not readily detected in existing submm-wave surveys. First, an additional population of dust-enshrouded galaxies with hot dust temperatures, perhaps dust-enshrouded, Compton-thick active galactic nuclei (AGN) as suggested by recent deep Chandra surveys. Secondly, a population of dusty galaxies with temperatures more typical of the existing submm-selected galaxies, but at relatively low redshifts. These could plausibly be associated with the assembly of groups and clusters of galaxies. Thirdly, a population of low-luminosity, cool, quiescent spiral galaxies. Hot AGN sources and the assembly of galaxy groups can account for the excess 60-\u03bcm background. There are significant problems with the cluster assembly scenario, in which too many bright 60-\u03bcm IRAS sources are predicted. Spiral galaxies have the wrong spectral energy distributions to account for the excess. Future wide-field far-infrared (IR) surveys at wavelengths of 70 and 250 \u03bcm using the SIRTF and Herschel space missions will sample representative volumes of the distant Universe, allowing any hot population of dusty AGNs and forming groups to be detected.", "date": "2002-06-11", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "333", "number": "1", "publisher": "Royal Astronomical Society", "pagerange": "222-230", "id_number": "CaltechAUTHORS:20180404-071358526", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180404-071358526", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Raymond and Beverly Sackler Foundation" }, { "agency": "NSF", "grant_number": "AST-9980846" } ] }, "doi": "10.1046/j.1365-8711.2002.05398.x", "primary_object": { "basename": "Blain_et_al-2002-Monthly_Notices_of_the_Royal_Astronomical_Society.pdf", "url": "https://authors.library.caltech.edu/records/g2pwq-c5e93/files/Blain_et_al-2002-Monthly_Notices_of_the_Royal_Astronomical_Society.pdf" }, "resource_type": "article", "pub_year": "2002", "author_list": "Blain, A.

", "abstract": "The surface density of populations of galaxies with steep/shallow source counts is increased/decreased by gravitational lensing magnification. These effects are usually called 'magnification bias' and 'depletion', respectively. However, if sources are demagnified by lensing, then the situation is reversed, and the detectable surface density of galaxies with a shallow source count, as expected at the faintest flux densities, is increased. In general, demagnified sources are difficult to detect and study: exquisite subarcsec angular resolution and surface brightness sensitivity are required, and emission from the lensing object must not dominate the image. These unusual conditions are expected to be satisfied for observations made of the dense swarm of demagnified images that could form very close to the line of sight through the centre of a rich cluster of galaxies using the forthcoming submillimetre-wave Atacama Large Millimeter Array (ALMA) interferometer. The demagnified images of most of the background galaxies lying within about 1 arcmin of a rich cluster of galaxies could be detected in a single 18-arcsec-diameter ALMA field centred on the cluster core, providing an effective increase in the ALMA field of view.

", "abstract": "The physics of gamma-ray bursts (GRBs) and their offsets from the centers of their host galaxies are used to investigate the evolutionary state of their progenitors, motivated by the popular idea that GRBs are linked with the cataclysmic collapse of massive stars. We suggest that GRB progenitors in the inner and outer regions of hosts may be intrinsically different: outer bursts appear to have systematically greater isotropic equivalent energies (or narrower jets). This may provide an interesting clue to the nature of GRBs and may reflect a relation between metallicity and the evolution of GRB progenitors. If true, this offset-isotropic luminosity correlation is a strong argument for a collapsar origin of long-duration GRBs.", "date": "2002-01-20", "date_type": "published", "publication": "Astrophysical Journal", "volume": "565", "number": "1", "publisher": "American Astronomical Society", "pagerange": "L9-L12", "id_number": "CaltechAUTHORS:20170408-164406358", "issn": "1538-4357", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20170408-164406358", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Consejo Nacional de Ciencia y Tecnolog\u00eda (CONACYT)" }, { "agency": "ORS Foundation" }, { "agency": "Secretar\u00eda de Educaci\u00f3n P\u00fablica (SEP)" } ] }, "doi": "10.1086/339018", "primary_object": { "basename": "0112156.pdf", "url": "https://authors.library.caltech.edu/records/54168-0v127/files/0112156.pdf" }, "related_objects": [ { "basename": "pdf", "url": "https://authors.library.caltech.edu/records/54168-0v127/files/pdf" } ], "resource_type": "article", "pub_year": "2002", "author_list": "Ramirez-Ruiz, Enrico; Lazzati, Davide; et el." }, { "id": "https://authors.library.caltech.eduhttps://authors.library.caltech.edu/records/f60py-b9y39", "eprint_id": 11308, "eprint_status": "archive", "datestamp": "2023-08-21 21:05:25", "lastmod": "2023-10-16 23:42:38", "type": "article", "metadata_visibility": "show", "creators": { "items": [ { "id": "Blain-A-W", "name": { "family": "Blain", "given": "A.

", "abstract": "The redshifted spectral line radiation emitted from both atomic fine-structure and molecular rotational transitions in the interstellar medium (ISM) of high-redshift galaxies can be detected in the centimetre, millimetre and submillimetre wavebands. Here we predict the counts of galaxies detectable in an array of molecular and atomic lines. This calculation requires a reasonable knowledge of both the surface density of these galaxies on the sky, and the physical conditions in their ISM. The surface density is constrained using the results of submillimetre-wave continuum surveys. Follow-up OVRO Millimeter Array observations of two of the galaxies detected in the dust continuum have provided direct measurements of CO rotational line emission at redshifts of 2.56 and 2.81. Based on these direct high-redshift observations and on models of the ISM that are constrained by observations of low-redshift ultraluminous infrared galaxies, we predict the surface density of line-emitting galaxies as a function of line flux density and observing frequency. We incorporate the sensitivities and mapping speeds of existing and future millimetre/submillimetre-wave telescopes and spectrographs, and so assess the prospects for blank-field surveys to detect this line emission from gas-rich high-redshift galaxies.", "date": "2000-04-11", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "313", "number": "3", "publisher": "Royal Astronomical Society", "pagerange": "559-570", "id_number": "CaltechAUTHORS:BLAmnras00", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:BLAmnras00", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Raymond and Beverly Sackler Foundation" }, { "agency": "Caltech Astronomy visitors' program" } ] }, "doi": "10.1046/j.1365-8711.2000.03287.x", "primary_object": { "basename": "BLAmnras00.pdf", "url": "https://authors.library.caltech.edu/records/f60py-b9y39/files/BLAmnras00.pdf" }, "resource_type": "article", "pub_year": "2000", "author_list": "Blain, A.
