", "abstract": "TIM, the Terahertz Intensity Mapper, is a NASA balloon mission designed to perform [CII] intensity mapping of the peak of cosmic star formation. To achieve this, TIM has two longslit (1 degree slit length) grating spectrometers covering the 240-317 um and 317-420 um wavelength bands at R~250, respectively. We will present the design of the ~4000 pixel, horn-coupled kinetic inductance detector arrays servicing each of the spectrometer arms. Each pixel is a lumped-element superconducting resonator made from a 20 nm thick aluminum film, designed to achieve photon noise limited performance at 100 fW of loading. The inductor is a meandered narrow wire, designed to mimic a metal mesh grid at THz frequencies; it is optimized for absorption of both polarizations delivered by the circular waveguide. Each array will consist of four quadrants containing ~1000 pixels on a single microstrip readout line and will be mounted such that critical parameters of the absorber design are maintained.", "date": "2020-12-13", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

In 1 000 h, surveys with the reference concept will detect from \u223c1.9\u00d710^6 to \u223c8.7\u00d710^6 lines from \u223c4.8\u00d710^5 to 2.7\u00d710^6 star-forming galaxies and from \u223c1.4\u00d710^4 to \u223c3.8\u00d710^4 lines from \u223c1.3\u00d710^4 to 3.5\u00d710^4 AGNs. The shallow survey will detect substantially more sources than the deep one; the advantage of the latter in pushing detections to lower luminosities/higher redshifts turns out to be quite limited. The OST/OSS will reach, in the same observing time, line fluxes more than one order of magnitude fainter than the SPICA/SMI and will cover a much broader redshift range. In particular it will detect tens of thousands of galaxies at z \u2265 5, beyond the reach of that instrument. The polycyclic aromatic hydrocarbons lines are potentially bright enough to allow the detection of hundreds of thousands of star-forming galaxies up to z \u223c 8.5, i.e. all the way through the reionisation epoch. The proposed surveys will allow us to explore the galaxy\u2013AGN co-evolution up to z \u223c 5.5\u22126 with very good statistics.

", "abstract": "Far-infrared astronomy has advanced rapidly since its inception in the late 1950s, driven by a maturing technology base and an expanding community of researchers. This advancement has shown that observations at far-infrared wavelengths are important in nearly all areas of astrophysics, from the search for habitable planets and the origin of life to the earliest stages of galaxy assembly in the first few hundred million years of cosmic history. The combination of a still-developing portfolio of technologies, particularly in the field of detectors, and a widening ensemble of platforms within which these technologies can be deployed, means that far-infrared astronomy holds the potential for paradigm-shifting advances over the next decade. We examine the current and future far-infrared observing platforms, including ground-based, suborbital, and space-based facilities, and discuss the technology development pathways that will enable and enhance these platforms to best address the challenges facing far-infrared astronomy in the 21st century.", "date": "2019-04", "date_type": "published", "publication": "Journal of Astronomical Telescopes, Instruments, and Systems", "volume": "5", "number": "2", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "pagerange": "Art.

With KISS support we have carried out the\nfollowing investigations:\n1) Developed the case for line intensity mapping methods to study the epoch of reionization\nusing singly ionized carbon (C+), typically the most luminous emission line in galaxies. The\ntheoretical studies not only explored the amplitude of the signal, and the usefulness in\ndetermining physical properties of the partially ionized intergalactic medium, but also the\neffects of foreground confusion from low-redshift galaxies. Our team made the first\ncalculations of C+ clustering fluctuations from the reionization epoch, and estimated the\neffect of foreground galaxy confusion, largely from CO line emission at z ~ 1. We also\nauthored the first papers on tomographic measurements with the Ly\uf061 emission line, which\nshows great promise for near-infrared intensity mapping measurements with the SPHEREx\nSMEX mission concept.\n2) Developed a complete design for a first-detection instrument of [CII] large-scale clustering\nemission named TIME-Pilot, based on an array of 32 novel waveguide spectrometers. The\nspectrometers are mounted in a linear array in two polarizations, and observations are\ncarried out by scanning the detectors in a 1-deg linear strip, which maximizes depth (small\nsurvey area) while preserving sensitivity on large scales (long scan length).\n3) Demonstrated the key waveguide spectrometer technology, which confines radiation in 2\ndimensions and the power propagates between parallel plates and is dispersed and\ncollimated by a curved grating. The waveguide spectrometers greatly reduce the mass and\nvolume that would otherwise be required with a conventional 3-d grating spectrometer.\n4) Demonstrated a prototype superconducting detector array. These high-sensitivity\nsuperconducting bolometers are mounted on the focal surface across multiple\nspectrometers, and read out by superconducting current amplifiers. The devices present\nunique micro-machining challenges to produce edge-butted sub-arrays that do not leave\nspectral gaps between channels.\n5) Completed the full cryogenic system for the instrument. We commandeered an existing 4\nK cryostat from another project, and added cooling stages to an ultimate temperature of\n220 mK to meet the TIME-Pilot cooling requirements. The system is fully tested and\noperational.\n6) Formed a partnership with ASIAA in Taiwan, led by Tzu-Ching Chang who attended the\noriginal KISS study. ASIAA is providing major hardware components for the TIME-Pilot\ninstrument, and in the past year have developed a prototype of the spectrometer, and\nprocured cables and cryogenic coolers.

", "abstract": "Measurements in the infrared wavelength domain allow direct assessment of the physical state and energy balance of cool matter in space, enabling the detailed study of the processes that govern the formation and evolution of stars and planetary systems in galaxies over cosmic time. Previous infrared missions revealed a great deal about the obscured Universe, but were hampered by limited sensitivity.\nSPICA takes the next step in infrared observational capability by combining a large 2.5-meter diameter telescope, cooled to below 8 K, with instruments employing ultra-sensitive detectors. A combination of passive cooling and mechanical coolers will be used to cool both the telescope and the instruments. With mechanical coolers the mission lifetime is not limited by the supply of cryogen. With the combination of low telescope background and instruments with state-of-the-art detectors SPICA provides a huge advance on the capabilities of previous missions.\nSPICA instruments offer spectral resolving power ranging from R ~50 through 11 000 in the 17\u2013230 \u03bcm domain and R~28.000 spectroscopy between 12 and 18 \u03bcm. SPICA will provide efficient 30\u201337 \u03bcm broad band mapping, and small field spectroscopic and polarimetric imaging at 100, 200 and 350 \u03bcm.

", "abstract": "The OSS on the Origins Space Telescope is designed to decode the cosmic history of nucleosynthesis, star formation, and supermassive black hole growth with wide-area spatial-spectral 3-D surveys across the full 25 to 590 micron band. Six wideband grating modules combine to cover the full band at R=300, each couples a long slit with 60-190 beams on the sky. OSS will have a total of 120,000 background-limited detector pixels in the six 2-D arrays which provide spatial and spectral coverage. The suite of grating modules can be used for pointed observations of targets of interest, and are particularly powerful for 3-D spectral spectral surveys. To chart the transition from interstellar material, particularly water, to planetary systems, two high-spectral-resolution modes are included. The first incorporates a Fourier-transform spectrometer (FTS) in front of the gratings providing resolving power of 25,000 (\u03b4v = 12 km/s) at 179 \u00b5m to resolve water emission in protoplanetary disk spectra. The second boosts the FTS capability with an additional etalon (Fabry-Perot interferometer) to provide 2 km/s resolution in this line to enable detailed structural studies of disks in the various water and HD lines. Optical, thermal, and mechanical designs are presented, and the system approach to the detector readout enabling the large formats is described.", "date": "2018-08-01", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "The Galaxy Evolution Probe (GEP) is a concept for a mid and far-infrared space observatory designed to survey sky for star-forming galaxies from redshifts of z = 0 to beyond z = 4. Furthering our knowledge of galaxy formation requires uniform surveys of star-forming galaxies over a large range of redshifts and environments to accurately describe star formation, supermassive black hole growth, and interactions between these processes in galaxies. The GEP design includes a 2 m diameter SiC telescope actively cooled to 4 K and two instruments: (1) An imager to detect star-forming galaxies and measure their redshifts photometrically using emission features of polycyclic aromatic hydrocarbons. It will cover wavelengths from 10 to 400 \u03bcm, with 23 spectral resolution R = 8 filter-defined bands from 10 to 95 \u03bcm and five R = 3.5 bands from 95 to 400 \u03bcm. (2) A 24 \u2013 193 \u03bcm, R = 200 dispersive spectrometer for redshift confirmation, identification of active galactic nuclei, and interstellar astrophysics using atomic fine-structure lines. The GEP will observe from a Sun-Earth L2 orbit, with a design lifetime of four years, devoted first to galaxy surveys with the imager and second to follow-up spectroscopy. The focal planes of the imager and the spectrometer will utilize KIDs, with the spectrometer comprised of four slit-coupled diffraction gratings feeding the KIDs. Cooling for the telescope, optics, and KID amplifiers will be provided by solar-powered cryocoolers, with a multi-stage adiabatic demagnetization refrigerator providing 100 mK cooling for the KIDs.", "date": "2018-07-24", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

Previous infrared missions, from IRAS to Herschel, have revealed a great deal about the obscured Universe, but sensitivity has been limited because up to now it has not been possible to fly a telescope that is both large and cold. Such a facility is essential to address key astrophysical questions, especially concerning galaxy evolution and the development of planetary systems. SPICA is a mission concept aimed at taking the next step in mid- and far-infrared observational capability by combining a large and cold telescope with instruments employing state-of-the-art ultra-sensitive detectors. The mission concept foresees a 2.5-meter diameter telescope cooled to below 8 K. Rather than using liquid cryogen, a combination of passive cooling and mechanical coolers will be used to cool both the telescope and the instruments. With cooling not dependent on a limited cryogen supply, the mission lifetime can extend significantly beyond the required three years. The combination of low telescope background and instruments with state-of-the-art detectors means that SPICA can provide a huge advance on the capabilities of previous missions. The SPICA instrument complement offers spectral resolving power ranging from ~50 through 11000 in the 17-230 \u00b5m domain as well as ~28.000 spectroscopy between 12 and 18 \u00b5m. Additionally, SPICA will be capable of efficient 30-37 \u00b5m broad band mapping, and small field spectroscopic and polarimetric imaging in the 100-350 \u00b5m range. SPICA will enable far infrared spectroscopy with an unprecedented sensitivity of ~5x10^(-20) W/m^2 (5\u03c3/1hr) - at least two orders of magnitude improvement over what has been attained to date. With this exceptional leap in performance, new domains in infrared astronomy will become accessible, allowing us, for example, to unravel definitively galaxy evolution and metal production over cosmic time, to study dust formation and evolution from very early epochs onwards, and to trace the formation history of planetary systems.", "date": "2018-07-10", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "Massive galaxy clusters have been found that date to times as early as three billion years after the Big Bang, containing stars that formed at even earlier epochs. The high-redshift progenitors of these galaxy clusters\u2014termed 'protoclusters'\u2014can be identified in cosmological simulations that have the highest overdensities (greater-than-average densities) of dark matter. Protoclusters are expected to contain extremely massive galaxies that can be observed as luminous starbursts. However, recent detections of possible protoclusters hosting such starbursts do not support the kind of rapid cluster-core formation expected from simulations: the structures observed contain only a handful of starbursting galaxies spread throughout a broad region, with poor evidence for eventual collapse into a protocluster. Here we report observations of carbon monoxide and ionized carbon emission from the source SPT2349-56. We find that this source consists of at least 14 gas-rich galaxies, all lying at redshifts of 4.31. We demonstrate that each of these galaxies is forming stars between 50 and 1,000 times more quickly than our own Milky Way, and that all are located within a projected region that is only around 130 kiloparsecs in diameter. This galaxy surface density is more than ten times the average blank-field value (integrated over all redshifts), and more than 1,000 times the average field volume density. The velocity dispersion (approximately 410 kilometres per second) of these galaxies and the enormous gas and star-formation densities suggest that this system represents the core of a cluster of galaxies that was already at an advanced stage of formation when the Universe was only 1.4 billion years old. A comparison with other known protoclusters at high redshifts shows that SPT2349-56 could be building one of the most massive structures in the Universe today.", "date": "2018-04-26", "date_type": "published", "publication": "Nature", "volume": "556", "number": "7702", "publisher": "Nature Publishing Group", "pagerange": "469-472", "id_number": "CaltechAUTHORS:20180430-111957676", "issn": "0028-0836", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180430-111957676", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NSF", "grant_number": "PLR-1248097" }, { "agency": "NSF", "grant_number": "PHY-1125897" }, { "agency": "Kavli Foundation" }, { "agency": "Gordon and Betty Moore Foundation", "grant_number": "GBMF 947" }, { "agency": "NSF", "grant_number": "AST-1312950" }, { "agency": "Natural Sciences and Engineering Research Council of Canada (NSERC)" }, { "agency": "Canada Foundation for Innovation" }, { "agency": "Killam Trust" }, { "agency": "Fondo Nacional de Desarrollo Cient\u00edfica y Tecnol\u00f3gico (FONDECYT)", "grant_number": "114009" }, { "agency": "Simons Foundation" }, { "agency": "Alfred P.

", "abstract": "Intensity mapping provides a unique means to probe the epoch of reionization (EoR), when the neutral intergalactic medium was ionized by energetic photons emitted from the first galaxies. The [C II] 158 \u03bcm fine-structure line is typically one of the brightest emission lines of star-forming galaxies and thus a promising tracer of the global EoR star formation activity. However, [C II] intensity maps at 6 \u227e z \u227e 8 are contaminated by interloping CO rotational line emission (3 \u2a7d J_(upp) \u2a7d 6) from lower-redshift galaxies. Here we present a strategy to remove the foreground contamination in upcoming [C II] intensity mapping experiments, guided by a model of CO emission from foreground galaxies. The model is based on empirical measurements of the mean and scatter of the total infrared luminosities of galaxies at z < 3 and with stellar masses M* > 10^8 M\u2299 selected in the K-band from the COSMOS/UltraVISTA survey, which can be converted to CO line strengths. For a mock field of the Tomographic Ionized-carbon Mapping Experiment, we find that masking out the \"voxels\" (spectral\u2013spatial elements) containing foreground galaxies identified using an optimized CO flux threshold results in a z-dependent criterion m^(AB)_K \u227e 22 (or M* \u2273 10^9 M\u2299)) at z < 1 and makes a [C II]/CO_(tot) power ratio of \u227310 at k = 0.1 h/Mpc achievable, at the cost of a moderate \u227e 8% loss of total survey volume.", "date": "2018-04-01", "date_type": "published", "publication": "Astrophysical Journal", "volume": "856", "number": "2", "publisher": "American Astronomical Society", "pagerange": "Art.

", "abstract": "The SPICA mid- and far-infrared telescope will address fundamental issues in our understanding of star formation and ISM physics in galaxies. A particular hallmark of SPICA is the outstanding sensitivity enabled by the cold telescope, optimised detectors, and wide instantaneous bandwidth throughout the mid- and far-infrared. The spectroscopic, imaging, and polarimetric observations that SPICA will be able to collect will help in clarifying the complex physical mechanisms which underlie the baryon cycle of galaxies. In particular, (i) the access to a large suite of atomic and ionic fine-structure lines for large samples of galaxies will shed light on the origin of the observed spread in star-formation rates within and between galaxies, (ii) observations of HD rotational lines (out to ~10 Mpc) and fine structure lines such as [C ii] 158 \u03bcm (out to ~100 Mpc) will clarify the main reservoirs of interstellar matter in galaxies, including phases where CO does not emit, (iii) far-infrared spectroscopy of dust and ice features will address uncertainties in the mass and composition of dust in galaxies, and the contributions of supernovae to the interstellar dust budget will be quantified by photometry and monitoring of supernova remnants in nearby galaxies, (iv) observations of far-infrared cooling lines such as [O i] 63 \u03bcm from star-forming molecular clouds in our Galaxy will evaluate the importance of shocks to dissipate turbulent energy.

These spectra explore an observed-frame 447\u20131568 GHz frequency range, allowing us to observe the main atomic and molecular lines emitted by gas in the interstellar medium. The sample is subdivided into redshift bins, and a subset of the bins are stacked by infrared luminosity as well. These stacked spectra are used to determine the average gas density and radiation field strength in the photodissociation regions (PDRs) of DSFGs. For the low-redshift sample, we present the average spectral line energy distributions of CO and H_2O rotational transitions and consider PDR conditions based on observed [C I] 370 and 609 \u03bcm, and CO (7-6) lines. For the high-z (0.8 < z < 4) sample, PDR models suggest a molecular gas distribution in the presence of a radiation field that is at least a factor of 10^3 larger than the Milky Way and with a neutral gas density of roughly 10^(4.5)-10^(5.5) cm^(\u22123). The corresponding PDR models for the low-z sample suggest a UV radiation field and gas density comparable to those at high-z. Given the challenges in obtaining adequate far-infrared observations, the stacked average spectra we present here will remain the measurements with the highest signal-to-noise ratio for at least a decade and a half until the launch of the next far-infrared facility.", "date": "2017-10-10", "date_type": "published", "publication": "Astrophysical Journal", "volume": "848", "number": "1", "publisher": "American Astronomical Society", "pagerange": "Art.

The PDR density and far-UV radiation fields inferred from the atomic lines are not consistent with the CO emission, indicating that the molecular gas excitation is not solely provided via UV heating from local star formation (SF), but requires an additional heating source. X-ray heating from the AGN is explored, and we find that X-ray-dominated region (XDR) models, in combination with PDR models, can match the CO cooling without overproducing the observed FS line emission. While this XDR/PDR solution is favored given the evidence for both X-rays and SF in the Cloverleaf, we also investigate alternatives for the warm molecular gas, finding that either mechanical heating via low-velocity shocks or an enhanced cosmic-ray ionization rate may also contribute. Finally, we include upper limits on two other measurements attempted in the Herschel program: [C II]158 \u03bcm in FSC 10214 and [O I]63 \u03bcm in APM 08279+5255.", "date": "2016-12-01", "date_type": "published", "publication": "Astrophysical Journal", "volume": "832", "number": "2", "publisher": "American Astronomical Society", "pagerange": "Art.

", "abstract": "Spectral line intensity mapping (LIM) has been proposed as a promising tool to efficiently probe the cosmic reionization and the large-scale structure. Without detecting individual sources, LIM makes use of all available photons and measures the integrated light in the source confusion limit to efficiently map the three-dimensional matter distribution on large scales as traced by a given emission line. One particular challenge is the separation of desired signals from astrophysical continuum foregrounds and line interlopers. Here we present a technique to extract large-scale structure information traced by emission lines from different redshifts, embedded in a three-dimensional intensity mapping data cube. The line redshifts are distinguished by the anisotropic shape of the power spectra when projected onto a common coordinate frame. We consider the case where high-redshift [C ii] lines are confused with multiple low-redshift CO rotational lines. We present a semi-analytic model for [C ii] and CO line estimates based on the cosmic infrared background measurements, and show that with a modest instrumental noise level and survey geometry, the large-scale [C ii] and CO power spectrum amplitudes can be successfully extracted from a confusion-limited data set, without external information. We discuss the implications and limits of this technique for possible LIM experiments.", "date": "2016-12-01", "date_type": "published", "publication": "Astrophysical Journal", "volume": "832", "number": "2", "publisher": "American Astronomical Society", "pagerange": "Art.

We plan to target a 1 degree by 0.35 arcminute field on the sky and a spectral range of 199-305 GHz, producing a spatial-spectral slab which is 140 Mpc by 0.9 Mpc on-end and 1230 Mpc in the redshift direction. With careful removal of intermediate-redshift CO sources, we anticipate a detection of the halo-halo clustering term in the [CII] power spectrum consistent with current models for star formation history in 240 hours on the JCMT. TIME-Pilot will use two stacks of 16 parallel-plate waveguide spectrometers (one stack per polarization) with a resolving power R ~ 100 and a spectral range of 183 to 326 GHz. The range is divided into 60 spectral channels, of which 16 at the band edges on each spectrometer serve as atmospheric monitors. The diffraction gratings are curved to produce a compact instrument, each focusing the diffracted light onto an output arc sampled by the 60 bolometers. The bolometers are built in buttable dies of 8 (low freqeuency) or 12 (high frequency) spectral channels by 8 spatial channels and are mated to the spectrometer stacks. Each detector consists of a gold micro-mesh absorber and a titanium transition edge sensor (TES). The detectors (1920 total) are designed to operate from a 250 mK base temperature in an existing cryostat with a photon-noise-dominated NEP of ~2 * 10^(-17) WHz^(-1-2). A set of flexible superconducting cables connect the detectors to a time-domain multiplexing SQUID readout system.", "date": "2016-07-19", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

The spectrometer employs a filter bank architecture, and consists of a series of half-wave resonators formed by lithographically-patterned superconducting transmission lines. The signal power admitted by each resonator is detected by a lumped element titanium nitride (TiN) kinetic inductance detector operating at 100\u2013200 MHz. We have tested a new prototype device that achieves the targeted R=100R=100 resolving power, and has better detector sensitivity and optical efficiency than previous devices. We employ a new method for measuring photon noise using both coherent and thermal sources of radiation to cleanly separate the contributions of shot and wave noise. We report an upper limit to the detector NEP of 1.4\u00d710^(\u221217) W Hz^(\u22121/2), within 10 % of the photon noise-limited NEP for a ground-based R=100R=100 spectrometer.", "date": "2016-07", "date_type": "published", "publication": "Journal of Low Temperature Physics", "volume": "184", "number": "1", "publisher": "Springer", "pagerange": "180-187", "id_number": "CaltechAUTHORS:20151222-084916037", "issn": "0022-2291", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20151222-084916037", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "APRA 399131.02.06.03.43" }, { "agency": "NSF", "grant_number": "ATI-1407287" } ] }, "local_group": { "items": [ { "id": "Keck-Institute-for-Space-Studies" } ] }, "doi": "10.1007/s10909-015-1375-x", "primary_object": { "basename": "1511.04488v1.pdf", "url": "https://authors.library.caltech.edu/records/299j6-fz226/files/1511.04488v1.pdf" }, "resource_type": "article", "pub_year": "2016", "author_list": "Hailey-Dunsheath, S.; Shirokoff, E.; et el." }, { "id": "https://authors.library.caltech.eduhttps://authors.library.caltech.edu/records/9bmzn-nt797", "eprint_id": 43987, "eprint_status": "archive", "datestamp": "2023-08-20 02:41:03", "lastmod": "2023-10-26 00:04:10", "type": "article", "metadata_visibility": "show", "creators": { "items": [ { "id": "Shirokoff-E", "name": { "family": "Shirokoff", "given": "E." } }, { "id": "Barry-P-S", "name": { "family": "Barry", "given": "P.

We present a characterization of a representative R = 282 channel at f = 236 GHz, including measurements of the spectrometer detection efficiency, the detector responsivity over a large range of optical loading, and the full system optical efficiency.

", "abstract": "TIME-Pilot is designed to make measurements from the Epoch of Reionization (EoR), when the first stars and galaxies formed and ionized the intergalactic medium. This will be done via measurements of the redshifted 157.7 um line of singly ionized carbon ([CII]). In particular, TIME-Pilot will produce the first detection of [CII] clustering fluctuations, a signal proportional to the integrated [CII] intensity, summed over all EoR galaxies. TIME-Pilot is thus sensitive to the emission from dwarf galaxies, thought to be responsible for the balance of ionizing UV photons, that will be difficult to detect individually with JWST and ALMA. A detection of [CII] clustering fluctuations would validate current theoretical estimates of the [CII] line as a new cosmological observable, opening the door for a new generation of instruments with advanced technology spectroscopic array focal planes that will map [CII] fluctuations to probe the EoR history of star formation, bubble size, and ionization state. Additionally, TIME-Pilot will produce high signal-to-noise measurements of CO clustering fluctuations, which trace the role of molecular gas in star-forming galaxies at redshifts 0 < z < 2. With its unique atmospheric noise mitigation, TIME-Pilot also significantly improves sensitivity for measuring the kinetic Sunyaev-Zel'dovich (kSZ) effect in galaxy clusters. TIME-Pilot will employ a linear array of spectrometers, each consisting of a parallel-plate diffraction grating. The spectrometer bandwidth covers 185-323 GHz to both probe the entire redshift range of interest and to include channels at the edges of the band for atmospheric noise mitigation. We illuminate the telescope with f/3 horns, which balances the desire to both couple to the sky with the best efficiency per beam, and to pack a large number of horns into the fixed field of view. Feedhorns couple radiation to the waveguide spectrometer gratings. Each spectrometer grating has 190 facets and provides resolving power above 100. At this resolution, the longest dimension of the grating is 31 cm, which allows us to stack gratings in two blocks (one for each polarization) of 16 within a single cryostat, providing a 1x16 array of beams in a 14 arcminute field of view. Direct absorber TES sensors sit at the output of the grating on six linear facets over the output arc, allowing us to package and read out the detectors as arrays in a modular manner. The 1840 detectors will be read out with the NIST time-domain-multiplexing (TDM) scheme and cooled to a base temperature of 250 mK with a 3He sorption refrigerator.

However, it remains unknown how soon after the Big Bang massive starburst progenitors exist. The measured redshift (z) distribution of dusty, massive starbursts has long been suspected to be biased low in z owing to selection effects, as confirmed by recent findings of systems with redshifts as high as ~5 (refs 2\u20134). Here we report the identification of a massive starburst galaxy at z = 6.34 through a submillimetre colour-selection technique. We unambiguously determined the redshift from a suite of molecular and atomic fine-structure cooling lines. These measurements reveal a hundred billion solar masses of highly excited, chemically evolved interstellar medium in this galaxy, which constitutes at least 40 per cent of the baryonic mass. A 'maximum starburst' converts the gas into stars at a rate more than 2,000 times that of the Milky Way, a rate among the highest observed at any epoch. Despite the overall downturn in cosmic star formation towards the highest redshifts, it seems that environments mature enough to form the most massive, intense starbursts existed at least as early as 880 million years after the Big Bang.", "date": "2013-04-18", "date_type": "published", "publication": "Nature", "volume": "496", "number": "7445", "publisher": "Nature Publishing Group", "pagerange": "329-333", "id_number": "CaltechAUTHORS:20130502-132215358", "issn": "0028-0836", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20130502-132215358", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "doi": "10.1038/nature12050", "primary_object": { "basename": "1304.4256.pdf", "url": "https://authors.library.caltech.edu/records/qj7sp-ywb34/files/1304.4256.pdf" }, "related_objects": [ { "basename": "nature12050-s1.pdf", "url": "https://authors.library.caltech.edu/records/qj7sp-ywb34/files/nature12050-s1.pdf" } ], "resource_type": "article", "pub_year": "2013", "author_list": "Riechers, Dominik A.; Bradford, C.

", "abstract": "Using the IRAM Plateau de Bure interferometer (PdBI), we report the detection of water vapor in six new lensed ultra-luminous starburst galaxies at high redshift, discovered in the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS). The sources are detected either in the 2_(02)\u22121_(11) or 2_(11)\u22122_(02) H_2O emission lines with integrated line fluxes ranging from 1.8 to 14 Jy km s^(-1). The corresponding apparent luminosities are \u03bcL_(H2O) ~ 3\u221212 \u00d7 10^8\u2009L_\u2299, where \u03bc is the lensing magnification factor (3 < \u03bc < 12). These results confirm that H_2O lines are among the strongest molecular lines in high-z ultra-luminous starburst galaxies, with intensities almost comparable to those of the high-J CO lines, and similar profiles and line widths (~200\u2212900 km s^(-1)). With the current sensitivity of the PdBI, the water lines can therefore easily be detected in high-z lensed galaxies (with F(500 \u03bcm)\u2009>\u2009100\u2009mJy) discovered in the Herschel surveys. Correcting the luminosities for amplification, using existing lensing models, L_(H2O) is found to have a strong dependence on the infrared luminosity, varying as ~L_(IR)^(1.2). This relation, which needs to be confirmed with better statistics, may indicate a role of radiative (infrared) excitation of the H_2O lines, and implies that high-z galaxies with L_(IR) \u2273 10^(13)\u2009L_\u2299 tend to be very strong emitters in water vapor, that have no equivalent in the local universe.", "date": "2013-03", "date_type": "published", "publication": "Astronomy and Astrophysics", "volume": "551", "publisher": "EDP Sciences", "pagerange": "Art.

", "abstract": "We present new observations from Z-Spec, a broadband 185-305 GHz spectrometer, of five submillimeter bright lensed sources selected from the Herschel-Astrophysical Terahertz Large Area Survey science demonstration phase catalog. We construct a redshift-finding algorithm using combinations of the signal to noise of all the lines falling in the Z-Spec bandpass to determine redshifts with high confidence, even in cases where the signal to noise in individual lines is low. We measure the dust continuum in all sources and secure CO redshifts for four out of five (z ~ 1.5-3). In one source, SDP.17, we tentatively identify two independent redshifts and a water line, confirmed at z = 2.308. Our sources have properties characteristic of dusty starburst galaxies, with magnification-corrected star formation rates of 10^(2\u20133) M_\u2609 yr^(\u20131). Lower limits for the dust masses (~a few 10^8 M_\u2609) and spatial extents (~1 kpc equivalent radius) are derived from the continuum spectral energy distributions, corresponding to dust temperatures between 54 and 69 K. In the local thermodynamic equilibrium (LTE) approximation, we derive relatively low CO excitation temperatures (\u2272100 K) and optical depths (\u03c4 \u2272 1). Performing a non-LTE excitation analysis using RADEX, we find that the CO lines measured by Z-Spec (from J = 4 \u2192 3 to 10 \u2192 9, depending on the galaxy) localize the best solutions to either a high-temperature/low-density region or a low/temperature/high-density region near the LTE solution, with the optical depth varying accordingly.

", "abstract": "SuperSpec is an ultra-compact spectrometer-on-a-chip for millimeter and submillimeter wavelength astronomy. Its very small size, wide spectral bandwidth, and highly multiplexed readout will enable construction of powerful multibeam spectrometers for high-redshift observations. The spectrometer consists of a horn-coupled microstrip feedline, a bank of narrow-band superconducting resonator filters that provide spectral selectivity, and kinetic inductance detectors (KIDs) that detect the power admitted by each filter resonator. The design is realized using thin-film lithographic structures on a silicon wafer. The mm-wave microstrip feedline and spectral filters of the first prototype are designed to operate in the band from 195-310 GHz and are fabricated from niobium with at T_c 9.2 K. The KIDs are designed to operate at hundreds of MHz and are fabricated from titanium nitride with a T_c of ~ 2 K. Radiation incident on the horn travels along the mm-wave microstrip, passes through the frequency-selective filter, and is finally absorbed by the corresponding KID where it causes a measurable shift in the resonant frequency. In this proceedings, we present the design of the KIDs employed in SuperSpec and the results of initial laboratory testing of a prototype device.

However, such TESs cannot be operated at 50mK unless stray power on the devices, or dark power P_D, is less than 200aW. We describe criteria for measuring P_D that requires accurate knowledge of T_C. Ultimately, we fabricated superconducting thermistors from Ir (T_C\u2265135mK) and Mo/Cu proximitized bilayers, where TC is the thermistor transition temperature. We measured the Ir TES arrays in our 45mK base temperature adiabatic demagnetization refrigerator test system, which can measure up to eight 1x32 arrays simultaneously using a time-division multiplexer, as well as our single-pixel test system which can measure down to 15mK. In our previous Ir array measurements our best reported performance was NEP=2.5\u00d710^(-19) W/Hz^(1/2) and \u03c4~5ms for straight-beam TESs. In fact, we expected NEP 1.5\u00d710^(-19)W/Hz^(1/2) for meander beam TESs, but did not achieve this previously due to 1/f noise. Here, we detail improvements toward measuring the expected NEP and demonstrate NEP=(1.3\u00b10.2)\u00d710^(-19)W/Hz^(1/2) in our single-pixel test system and NEP=(1.6\u00b10.3)\u00d710^(-19)W/Hz^(1/2) in our array test system.", "date": "2012-09-24", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "The Sunyaev-Zel'dovich (SZ) effect spectrum crosses through a null where \u0394T_CMB = 0 near \u03bd_0 = 217 GHz. In a cluster of galaxies, \u03bd0 can be shifted from the canonical thermal SZ effect value by corrections to the SZ effect scattering due to the properties of the inter-cluster medium. We have measured the SZ effect in the hot galaxy cluster RX J 1347.5 \u2013 1145 with Z-Spec, an R ~ 300 grating spectrometer sensitive between 185 and 305 GHz. These data comprise a high spectral resolution measurement around the null of the SZ effect and clearly exhibit the transition from negative to positive \u0394T_CMB over the Z-Spec band. The SZ null position is measured to be \u03bd_0 = 225.8 \u00b1 2.5(stat.) \u00b1 1.2(sys.) GHz, which differs from the canonical null frequency by 3.0\u03c3 and is evidence for modifications to the canonical thermal SZ effect shape. Assuming the measured shift in \u03bd0 is due only to relativistic corrections to the SZ spectrum, we place the limit kT_e = 17.1 \u00b1 5.3 keV from the zero-point measurement alone.

", "abstract": "The atomic C II fine-structure line is one of the brightest lines in a typical star-forming galaxy spectrum with a luminosity ~0.1%-1% of the bolometric luminosity. It is potentially a reliable tracer of the dense gas distribution at high redshifts and could provide an additional probe to the era of reionization. By taking into account the spontaneous, stimulated, and collisional emission of the C II line, we calculate the spin temperature and the mean intensity as a function of the redshift. When averaged over a cosmologically large volume, we find that the C II emission from ionized carbon in individual galaxies is larger than the signal generated by carbon in the intergalactic medium. Assuming that the C II luminosity is proportional to the carbon mass in dark matter halos, we also compute the power spectrum of the C II line intensity at various redshifts. In order to avoid the contamination from CO rotational lines at low redshift when targeting a C II survey at high redshifts, we propose the cross-correlation of C II and 21 cm line emission from high redshifts. To explore the detectability of the C II signal from reionization, we also evaluate the expected errors on the C II power spectrum and C II-21 cm cross power spectrum based on the design of the future millimeter surveys. We note that the C II-21 cm cross power spectrum contains interesting features that capture physics during reionization, including the ionized bubble sizes and the mean ionization fraction, which are challenging to measure from 21 cm data alone. We propose an instrumental concept for the reionization C II experiment targeting the frequency range of ~200-300 GHz with 1, 3, and 10 m apertures and a bolometric spectrometer array with 64 independent spectral pixels with about 20,000 bolometers.", "date": "2012-01-20", "date_type": "published", "publication": "Astrophysical Journal", "volume": "745", "number": "1", "publisher": "American Astro745nomical Society", "pagerange": "Art.

", "abstract": "We present the rest-frame 200-320 \u03bcm spectrum of the z = 3.91 quasar APM 08279+5255, obtained with Z-Spec at the Caltech Submillimeter Observatory. In addition to the J = 8 \u2192 7 to J = 13 \u2192 12 CO rotational transitions which dominate the CO cooling, we find six transitions of water originating at energy levels ranging up to 643 K. Most are first detections at high redshift, and we have confirmed one transition with CARMA. The CO cooling is well described by our X-ray dominated region (XDR) model, assuming L_(1-100 keV) ~ 1 \u00d7 10^(46) erg s^(\u20131), and that the gas is distributed over a 550-pc size scale, as per the now-favored \u03bc = 4 lensing model. The total observed cooling in water corresponds to 6.5 \u00d7 109 L_\u2609, comparable to that of CO. We compare the water spectrum with that of Mrk 231, finding that the intensity ratios among the high-lying lines are similar, but with a total luminosity scaled up by a factor of ~50. Using this scaling, we estimate an average water abundance relative to H_2 of 1.4 \u00d7 10^(\u20137), a good match to the prediction of the chemical network in the XDR model. As with Mrk 231, the high-lying water transitions are excited radiatively via absorption in the rest-frame far-infrared, and we show that the powerful dust continuum in APM 08279+5255 is more than sufficient to pump this massive reservoir of warm water vapor.", "date": "2011-11-10", "date_type": "published", "publication": "Astrophysical Journal Letters", "volume": "741", "number": "2", "publisher": "American Astronomical Society", "pagerange": "L37", "id_number": "CaltechAUTHORS:20111209-094523752", "issn": "2041-8205", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20111209-094523752", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "NAGS-11911" }, { "agency": "NASA", "grant_number": "NAGS-12788" }, { "agency": "NSF", "grant_number": "AST-0807990" }, { "agency": "NSF", "grant_number": "AST-0239270" }, { "agency": "Research Corporation", "grant_number": "RI0928" }, { "agency": "Caltech Millikan Fellowship" }, { "agency": "JPL Director's fellowship" }, { "agency": "NRAO Jansky fellowship" }, { "agency": "NASA Graduate Student Research Fellowship" }, { "agency": "NSF Graduate Research Fellowship" } ] }, "doi": "10.1088/2041-8205/741/2/L37", "primary_object": { "basename": "Bradford2011p16475Astrophys_J_Lett.pdf", "url": "https://authors.library.caltech.edu/records/kgr1r-nsy06/files/Bradford2011p16475Astrophys_J_Lett.pdf" }, "resource_type": "article", "pub_year": "2011", "author_list": "Bradford, 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.

The derived upper limit to the line-to-continuum flux ratio is 0.1\u20130.3 (2\u03c3) across the Z-Spec band.\nBased on the analysis of the derived spectral energy distribution from optical to radio wavelengths of possible counterparts near the SMA/CARMA peak position, we suggest that Orochi is a lensed, optically dark SMG lying at\u2002z\u2002\u223c 3.4 behind a foreground, optically visible (but red) galaxy at\u2002z\u2002\u223c 1.4. The deduced apparent (i.e., no correction for magnification) infrared luminosity (L_(IR)) and star formation rate (SFR) are 6 \u00d7 10^(13) L_\u2299 and 11 000 M_\u2299 yr^(\u22121), respectively, assuming that the\u2002L_(IR) is dominated by star formation. These values suggest that Orochi will consume its gas reservoir within a short time-scale (3 \u00d7 10^7 yr), which is indeed comparable to those in extreme starbursts like the centres of local ultraluminous infrared galaxies (ULIRGs).", "date": "2011-08", "date_type": "published", "publication": "Monthly Notices of the Royal Astronomical Society", "volume": "415", "number": "4", "publisher": "Royal Astronomical Society", "pagerange": "3081-3096", "id_number": "CaltechAUTHORS:20110927-132054052", "issn": "0035-8711", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20110927-132054052", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Ministry of Education, Culture, Sports, Science and Technology (MEXT)", "grant_number": "20001003" }, { "agency": "Smithsonian Institution" }, { "agency": "Gordon and Betty Moore Foundation" }, { "agency": "Kenneth T. and Eileen L.

", "abstract": "The Herschel survey, H-ATLAS, with its large areal coverage, has recently discovered a number of bright, strongly lensed high-z submillimeter galaxies. The strong magnification makes it possible to study molecular species other than CO, which are otherwise difficult to observe in high-z galaxies. Among the lensed galaxies already identified by H-ATLAS, the source J090302.9-014127B (SDP.17b) at z = 2.305 is remarkable because of its excitation conditions and a tentative detection of the H_2O 2_(02)-1_(11) emission line (Lupu et al. 2010, ApJ, submitted). We report observations of this line in SDP.17b using the IRAM interferometer equipped with its new 277\u2013371\u2009GHz receivers. The H_2O line is detected at a redshift of z = 2.3049 \u00b1 0.0006, with a flux of 7.8 \u00b1 0.5 Jy km s^(-1) and a FWHM of 250 \u00b1 60 \u2009 km \u2009 s^(-1). The new flux is 2.4 times weaker than the previous tentative detection, although both remain marginally consistent within 1.6\u03c3. The intrinsic line luminosity and ratio of H_2O(2_(02) \u2212 1_(11))/CO(8 \u2212 7) are comparable with those of the nearby starburst/enshrouded-AGN Mrk 231, and the ratio I(H_2O)/L_(FIR) is even higher, suggesting that SDP.17b could also host a luminous AGN. The detection of a strong H_2O 2_(02) \u2212 1_(11) line in SDP.17b implies an efficient excitation mechanism of the water levels that must occur in very dense and warm interstellar gas probably similar to Mrk 231.", "date": "2011-06", "date_type": "published", "publication": "Astronomy and Astrophysics", "volume": "530", "publisher": "EDP Sciences", "pagerange": "Art.

", "abstract": "We report on the redshift measurement and CO line excitation of HERMES J105751.1+573027 (HLSW-01), a strongly lensed submillimeter galaxy discovered in Herschel/SPIRE observations as part of the Herschel Multi-tiered Extragalactic Survey (HerMES). HLSW-01 is an ultra-luminous galaxy with an intrinsic far-infrared luminosity of L _(FIR) = 1.4 \u00d7 10^(13) L _\u2299, and is lensed by a massive group of galaxies into at least four images with a total magnification of \u03bc = 10.9 \u00b1 0.7. With the 100 GHz instantaneous bandwidth of the Z-Spec instrument on the Caltech Submillimeter Observatory, we robustly identify a redshift of z = 2.958 \u00b1 0.007 for this source, using the simultaneous detection of four CO emission lines (J = 7 \u2192 6, J = 8 \u2192 7, J = 9 \u2192 8, and J = 10 \u2192 9). Combining the measured line fluxes for these high-J transitions with the J = 1 \u2192 0, J = 3 \u2192 2, and J = 5 \u2192 4 line fluxes measured with the Green Bank Telescope, the Combined Array for Research in Millimeter Astronomy, and the Plateau de Bure Interferometer, respectively, we model the physical properties of the molecular gas in this galaxy. We find that the full CO spectral line energy distribution is described well by warm, moderate-density gas with T _(kin) = 86-235 K and n_H_2 = (1.1-3.5)x10^3 cm^(\u20133). However, it is possible that the highest-J transitions are tracing a small fraction of very dense gas in molecular cloud cores, and two-component models that include a warm/dense molecular gas phase with T _(kin) ~ 200 K, n_H_2 ~ 10^5 cm^(\u20133) are also consistent with these data. Higher signal-to-noise measurements of the J _(up) \u2265 7 transitions with high spectral resolution, combined with high spatial resolution CO maps, are needed to improve our understanding of the gas excitation, morphology, and dynamics of this interesting high-redshift galaxy.", "date": "2011-05-20", "date_type": "published", "publication": "Astrophysical Journal", "volume": "733", "number": "1", "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 present a 190-307 GHz broadband spectrum obtained with Z-Spec of NGC 1068 with new measurements of molecular rotational transitions. After combining our measurements with those previously published and considering the specific geometry of this Seyfert 2 galaxy, we conduct a multi-species Bayesian likelihood analysis of the density, temperature, and relative molecular abundances of HCN, HNC, CS, and HCO+. We find that these molecules trace warm (T>100 K) gas of H_2 number densities 10^(4.2)-10^(4.9) cm^(\u20133). Our models also place strong constraints on the column densities and relative abundances of these molecules, as well as on the total mass in the circumnuclear disk. Using the uniform calibration afforded by the broad Z-Spec bandpass, we compare our line ratios to X-ray-dominated region (XDR) and photon-dominated region models. The majority of our line ratios are consistent with the XDR models at the densities indicated by the likelihood analysis, lending substantial support to the emerging interpretation that the energetics in the circumnuclear disk of NGC 1068 are dominated by accretion onto an active galactic nucleus.", "date": "2011-04-20", "date_type": "published", "publication": "Astrophysical Journal", "volume": "731", "number": "2", "publisher": "American Astronomical Society", "pagerange": "Art.

SPICAs large cold aperture allows mid-IR to submm observations which are limited only by the natural backgrounds, and BLISS is designed to operate near this fundamental limit. BLISS-SPICA is 6 orders of magnitude faster than the spectrometers on Herschel and SOFIA in obtaining full-band spectra. It enables spectroscopy of dust-obscured galaxies at all epochs back to the rst billion years after the Big Bang (redshift 6), and study of all stages of planet formation in circumstellar disks. BLISS covers 35 - 433 microns range in ve or six wavelength bands, and couples two 2 sky positions simultaneously. The instrument is cooled to 50 mK for optimal sensitivity with an on-board refrigerators. The detector package is 4224 silicon-nitride micro-mesh leg-isolated bolometers with superconducting transition-edge-sensed (TES) thermistors, read out with a cryogenic time-domain multiplexer. All technical elements of BLISS have heritage in mature scientic instruments, and many have own. We report on our design study in which we are optimizing performance while accommodating SPICAs constraints, including the stringent cryogenic mass budget. In particular, we present our progress in the optical design and waveguide spectrometer prototyping.

BLISS is a broadband (38 \u03bcm\u2013433 \u03bcm), grating spectrometer consisting of five wavebands each with a modest resolution of R \u223c1000. Because BLISS requires the effective noise equivalent power (NEP) of the TES to be below 10^(-19) W/Hz^(1/2), our TESs consist of four long (1000 \u03bcm), narrow (0.4 \u03bcm), and thin (0.25 \u03bcm) Si_xN_y support beams that reduce the thermal conductance G between the substrate and the optical absorber. To reduce the heat capacity of the absorber and make the response time \u03c4 fast enough for BLISS, our absorbers are patterned into a mesh geometry with a fill factor of less than 10%. We use a bilayer of Ti/Au to make the effective impedance of the absorber match the impedance of the incoming radiation for each band. Measurements of the response time of the metallized absorbers to heat pulses show that their heat capacity exceeds the predictions of the Debye model. Our results are suggestive that the surface of the low pressure chemical vapor deposition (LPCVD) Si_xN_y used in the absorbers' construction is the source of microstates that dominate the heat capacity.", "date": "2009-12-16", "date_type": "published", "publisher": "American Institute of Physics", "place_of_pub": "Melville, NY", "pagerange": "56-59", "id_number": "CaltechAUTHORS:20160511-135208362", "isbn": "978-0-7354-0751-0", "book_title": "Low temperature detectors, LTD-13", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20160511-135208362", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA/JPL/Caltech" } ] }, "contributors": { "items": [ { "id": "Young-B", "name": { "family": "Young", "given": "Betty" } }, { "id": "Cabrera-B", "name": { "family": "Cabrera", "given": "Blas" } }, { "id": "Miller-A", "name": { "family": "Miller", "given": "Aaron" } } ] }, "doi": "10.1063/1.3292406", "primary_object": { "basename": "1.3292406.pdf", "url": "https://authors.library.caltech.edu/records/qkrah-rzb42/files/1.3292406.pdf" }, "resource_type": "book_section", "pub_year": "2009", "author_list": "Kenyon, M.; Day, P.

", "abstract": "We present the first broadband \u03bb = 1 mm spectrum toward the z = 2.56 Cloverleaf quasar, obtained with Z-Spec, a grating spectrograph on the 10.4 m Caltech Submillimeter Observatory. The 190-305 GHz observation band corresponds to the rest frame 272-444 \u03bcm, and we measure the dust continuum as well as all four transitions of carbon monoxide (CO) lying in this range. The power-law dust emission, F_\u03bd = 14 mJy(\u03bd/240 GHz)^(3.9) is consistent with the published continuum measurements. The CO J = 6 \u2192 5, J = 8 \u2192 7, and J = 9 \u2192 8 measurements are the first, and now provide the highest-J CO information in this source. Our measured CO intensities are very close to the previously published interferometric measurements of J = 7 \u2192 6, and we use all available transitions and our ^(13)CO upper limits to constrain the physical conditions in the Cloverleaf molecular gas disk. We find a large mass (2-50 \u00d7 10^9 M_\u2299) of highly excited gas with thermal pressure nT > 10^6 K cm^(\u20133). The ratio of the total CO cooling to the far-IR dust emission exceeds that in the local dusty galaxies, and we investigate the potential heating sources for this bulk of warm molecular gas. We conclude that both UV photons and X-rays likely contribute, and discuss implications for a top-heavy stellar initial mass function arising in the X-ray-irradiated starburst.

", "abstract": "To meet the 10 \u00b5m RMS half wavefront error requirement for the 25 m diameter Cornell Caltech Atacama Telescope (CCAT), active control of the approximately 200 primary mirror panels is required. The CCAT baseline design includes carbon fiber aluminum honeycomb sandwich mirror panels. Distortions of the panels due to thermal gradients, gravity and the mounting scheme need to be taken into consideration in the control system design. We have modeled the primary mirror surface as both flat and curved surfaces and have investigated mirror controllability with a variety of sensor types and positions. To study different mirror segmentation schemes and find acceptable sensor configurations, we have created a software package that supports multiple segment shapes and reconfigurable panel sizing and orientation. It includes extensible sensor types and flexible positioning. Inclusion of panel and truss deformations allows modeling the effects of thermal and gravity distortions on mirror controllability. Flat mirrors and curved mirrors with the correct prescription give similar results for controlled modes, but show significant differences in the unsensed flat mirror modes. Both flat and curved mirror models show that sensing schemes that work well with rigid, thermally stable panels will not control a mirror with deformable panels. Sensors external to the mirror surface such as absolute distance measurement systems or Shack-Hartmann type sensors are required to deal with panel deformations. Using a combination of segment based sensors and external sensors we have created a promising prototype control system for the CCAT telescope.", "date": "2008-07-17", "date_type": "published", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

The Cryogenic Aperture Large Infrared Space Telescope Observatory, or CALISTO, is based on an off-axis Gregorian telesocope having a 4 m by 6 m primary reflector. This can be launched using an Atlas V 511, with the only optical deployment required being a simple hinged rotation of the secondary reflector. The off-axis design, which includes a cold stop, offers exceptionally good performance in terms of high efficiency and minimum coupling of radiation incident from angles far off the direction of maximum response. This means that strong astronomical sources, such as the Milky Way and zodiacal dust in the plane of the solar system, add very little to the background. The entire optical system is cooled to 4 K to make its emission less than even this low level of astronomical emission. Assuming that detector technology can be improved to the point where detector noise is less than that of the astronomical background, we anticipate unprecedented low values of system noise equivalent power, in the vicinity of 10^(-19) WHz^(-0.5), through CALISTO's operating range.

", "abstract": "We report on the status of Z-Spec, including preliminary results of our first astronomical measurements. Z-Spec is a cryogenic, broadband, millimeter-wave grating spectrometer designed for molecular line surveys of galaxies, including carbon monoxide redshift measurements of high-redshift submillimeter sources. With an instantaneous bandwidth of 185-305 GHz, Z-Spec covers the entire 1 mm atmospheric transmission window with a resolving power of 200-400. The spectrometer employs the Waveguide Far-Infrared Spectrometer (WaFIRS) architecture, in which the light propagation is confined within a parallel-plate waveguide, resulting in a minimum mechanical envelope. Its array of 160 silicon-nitride micromesh bolometers is cooled to below 100 mK for background-limited performance. With its sensitivity, broad bandwidth, and compactness, Z-Spec serves as a prototype for a future far-IR spectrometer aboard a cold telescope in space. Z-Spec successfully demonstrated functionality with a partial array of detectors and warm electronics during a week-long engineering run at the Caltech Submillimeter Observatory in June, 2005. We describe the instrument performance evaluated at the telescope and in subsequent laboratory tests and compare these results with design specifications. Following several modifications we returned to the telescope in April, 2006. We present a preliminary astronomical spectrum and discuss our plans to improve sensitivity and throughput to achieve our ultimate science goals.", "date": "2006-07-06", "date_type": "published", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_pub": "Bellingham, WA", "pagerange": "Art.

", "abstract": "We present the design, integration, and first ryogenic testing of our new broad-band millimeter-wave spectrometer, Z-Spec. Z-Spec uses a novel architecture called WaFIRS (Waveguide Far-IR Spectrometer), which employs a curved diffraction grating in a parallel-plate waveguide propagation medium. The instrument will provide a resolving power betwee 200 and 350 across an instantaneous bandwidth of 190-310 GHz, all packaged within a cryostat that is of order 1 meter in size. For background-limited astronomical observations in the 1mm terrestrial window, Z-Spec uses 160 silicon nitride micro-mesh bolometers and the detectors and waveguide grating are cooled to ~0.1 K. Our first cryogenic measurements at 225 GHz show resolving power greater than 200, and the end-to-end throughput is estimated to be greater than 30%, possibly as high as 40%. Z-Spec represents the first systematic approach to cosmological redshift measurement that is not based on optical or near-IR identifications. With its good sensitivity and large bandwidth, Z-Spec provides a new capability for millimeter-wave astrophysics. The instrument will be capable of measureing rotational carbon monoxide line emission from bright dusty galaxies at redshifts of up to 4, and the broad bandwidth insures that at least two lines will be simultaneously detected, providing an unambiguous redshift determination. In addition to Z-Spec's observations over the next 1-3 years, the WaFIRS spectrometer architecture makes an excellent candidate for mid-IR to millimeter-wave spectrometers on future space-borned and suborbital platforms such as SPICA and SAFIR. The concept is dramatically more compact and lightweight than conventional free-space grating spectrometers, and no mirrors or lenses are used in the instrument.

", "abstract": "The discovery of galaxies beyond z~1 which emit the bulk of their luminosity at long wavelengths has demonstrated the need for high-sensitivity, broad-band spectroscopy in the far-IR/submm/mm bands. Because many of these sources are not detectable in the optical, long-wavelength spectroscopy is key to measuring their redshifts and ISM conditions. The continuum source list will increase in the coming decade with new ground-based instruments (SCUBA2, Bolocam, MAMBO), and the surveys of HSO and SIRTF. Yet the planned spectroscopic capabilities lag behind, in part due to the difficulty in scaling existing IR spectrograph designs to longer wavelengths. To overcome these limitations, we are developing WaFIRS, a novel concept for long-wavelength spectroscopy which utilizes a parallel-plate waveguide and a curved diffraction grating. WaFIRS provides the large (~60%) instantaneous bandwidth and high throughput of a conventional grating system, but offers a dramatic reduction in volume and mass. WaFIRS requires no space overheads for extra optical elements beyond the diffraction grating itself, and is two-dimensional because the propagation is confined between two parallel plates. Thus several modules could be stacked to multiplex either spatially or in different frequency bands. The size and mass savings provide opportunities for spectroscopy from space-borne observatories which would be impractical with traditional spectrographs. With background-limited detectors and a cooled 3.5 m telescope, the line sensitivity would be comparable to that of ALMA, with instantaneous broad-band coverage.

Relative to their optical-wavelength counterparts, the submillimeter observatories are both small in units of wavelength, and hot in units of photon energy, which imposes limits on their angular resolution and sensitivity. Nevertheless, even the modest far-IR and submillimeter observations obtained in the last two decades have revolutionized our understanding the physics and chemistry of the ISM, the formation of stars, and the cosmic history of these processes. The demonstration by COBE that about half of the radiant energy released in the universe since decoupling comes to us in the submm/far-IR has further underscored the scientific necessity of observations in this wavelength regime [8, 4, 5].

", "abstract": "The South Pole Imaging Fabry-Perot Interferometer (SPIFI) is the first instrument of its kind -a direct-detection imaging spectrometer for astronomy in the submillimeter band. SPIFI 's focal plane is a square array of 25 silicon bolometers cooled to 60 mK; the spectrometer consists of two cryogenic scanning Fabry-Perot interferometers in series with a 60-mK bandpass filter. The instrument operates in the short submillimeter windows (350 and 450 \u03bcm) available from the ground, with spectral resolving power selectable between 500 and 10,000. At present, SPIFI's sensitivity is within a factor of 1.5-3 of the photon background limit, comparable with the best heterodyne spectrometers. The instrument 's large bandwidth and mapping capability provide substantial advantages for specific astrophysical projects, including deep extragalactic observations.
