Millimeter-wave refracting telescopes targeting the degree-scale structure of the cosmic microwave background (CMB) have recently grown to diffraction-limited apertures of over 0.5 m. These instruments are entirely housed in vacuum cryostats to support their subkelvin bolometric detectors and to minimize radiative loading from thermal emission due to absorption loss in their transmissive optical elements. The large vacuum window is the only optical element in the system at ambient temperature, and therefore minimizing loss in the window is crucial for maximizing detector sensitivity. This motivates the use of low-loss polymer materials and a window as thin as practicable. However, the window must simultaneously meet the requirement to keep a sufficient vacuum, and therefore must limit gas permeation and remain mechanically robust against catastrophic failure under pressure. We report on the development of extremely thin composite polyethylene window technology that meets these goals. Two windows have been deployed for two full observing seasons on the BICEP3 and the 150 GHz BICEP Array receiver CMB telescopes at the South Pole. On BICEP3, the window has demonstrated a 6% improvement in detector sensitivity.

The combined lensing band powers represent the most precise CMB lensing power spectrum measurement to date with a signal-to-noise ratio of 61 and an amplitude of \ud835\udc34reconlens=1.025±0.017 with respect to the theory prediction from the best-fit CMB Planck-ACT cosmology.

Including dark energy spectroscopic instrument baryon acoustic oscillation (BAO) data improves the constraint on the amplitude of matter fluctuations to \ud835\udf0e\u2088 =0.829 ±0.009 (a 1.1% determination).

The joint lensing constraints on structure growth and present-day Hubble rate are fully consistent with a Λ\u2062CDM model fit to the primary CMB data from Planck and ACT. While the precise upper limit is sensitive to the choice of data and underlying model assumptions, when varying the neutrino mass sum within the Λ\u2062CDM cosmological model, the combination of primary CMB, BAO, and CMB lensing drives the probable upper limit for the mass sum towards lower values, comparable to the minimum mass prior required by neutrino oscillation experiments.

data at 95 GHz and 150 GHz taken in 2018. The lensing amplitude relative to a fiducial Planck 2018 Lambda cold dark matter (\u039bCDM) cosmology is found to be 1.020 \u00b1 0.060, excluding instrumental and astrophysical systematic uncertainties. We conduct extensive systematic and null tests to check the robustness of the lensing measurements, and report a minimum-variance combined lensing power spectrum over angular multipoles of 50 < L < 2000, which we use to constrain cosmological models. When analyzed alone and jointly with primary cosmic microwave background (CMB) spectra within the \u039bCDM model, our lensing amplitude measurements are consistent with measurements from SPT-SZ, SPTpol, ACT, and Planck. Incorporating loose priors on the baryon density and other parameters including uncertainties on a foreground bias template, we obtain a 1\u03c3 constraint on \u03c3\u2088\u03a9\u2098^(0.25) = 0.595 \u00b1 0.026 using the SPT-3G 2018 lensing data alone, where \u03c38 is a common measure of the amplitude of structure today and \u03a9\u2098 is the matter density parameter. Combining SPT-3G 2018 lensing measurements with baryon acoustic oscillation (BAO) data, we derive parameter constraints of \u03c3\u2088 = 0.810 \u00b1 0.033, S\u2088 \u2261 \u03c3\u2088(\u03a9\u2098/0.3)^(0.5) = 0.836 \u00b1 0.039, and Hubble constant H\u2080 =68.8^+1.3)_(\u22121.6)\u2009\u2009km\u2009s\u207b\u00b9\u2009Mpc\u207b\u00b9. Our preferred S\u2088 value is higher by 1.6 to 1.8\u03c3 compared to cosmic shear measurements from DES-Y3, HSC-Y3, and KiDS-1000 at lower redshift and smaller scales. We combine our lensing data with CMB anisotropy measurements from both SPT-3G and Planck to constrain extensions of \u039bCDM. Using CMB anisotropy and lensing measurements from SPT-3G only, we provide independent constraints on the spatial curvature of \u03a9_K = 0.014^(+0.023)_(\u22120.026) (95% C.L.) and the dark energy density of \u03a9_\u039b = 0.722^(+0.031)_(\u22120.026) (68% C.L.). When combining SPT-3G lensing data with SPT-3G CMB anisotropy and BAO data, we find an upper limit on the sum of the neutrino masses of \u2211m_\u03bd < 0.30\u2009\u2009eV (95% C.L.). Due to the different combination of angular scales and sky area, this lensing analysis provides an independent check on lensing measurements by ACT and Planck.

Over the next few years, the \"Stage-3\" BICEP Array (BA) telescope will improve the program's frequency coverage and sensitivity to primordial B-mode polarization by an order of magnitude. The first receiver in the array, BA1, began observing at 30/40 GHz in early 2020. The next two receivers, BA2 and BA3, are currently being assembled and will map the southern sky at frequencies ranging from 95 to 150 GHz. Common to all BA receivers is a refractive, on-axis, cryogenic optical design that focuses microwave radiation onto a focal plane populated with antenna-coupled bolometers. High-performance antireflective coatings up to 760 mm in aperture are needed for each element in the optical chain, and must withstand repeated thermal cycles down to 4 K. Here, we present the design and fabrication of the 30/40 GHz anti-reflection coatings for the recently deployed BA1 receiver, with indices matched to its various polyethylene, nylon and alumina optical components. We describe an epoxy coating technique designed for alumina optics, which achieves better than 80% transmission at room temperature. For polyethylene optical elements, we present a new heat-compression approach that allows low-density polytetrafluoroethylene AR layers to reach sub-percent reflected power. We describe the planned use of these methods for the next BA cryostats, which may inform technological choices for future small-aperture telescopes of the CMB-S4 experiment.", "doi": "10.1007/s10909-023-02967-1", "issn": "0022-2291", "publisher": "Springer", "publication": "Journal of Low Temperature Physics", "publication_date": "2023-06-05" }, { "id": "authors:md2mf-ndy43", "collection": "authors", "collection_id": "md2mf-ndy43", "cite_using_url": "https://resolver.caltech.edu/CaltechAUTHORS:20230705-476466000.4", "type": "article", "title": "BICEP/Keck.

Cosmological constraints are derived from three of the distortion fields concerning gravitational lensing from large-scale structure, polarization rotation from magnetic fields or an axion-like field, and the screening effect of patchy reionization. We measure an amplitude of the lensing power spectrum A^(\u03d5\u03d5)_(L) = 0.95 \u00b1 0.20. We constrain polarization rotation, expressed as the coupling constant of a Chern\u2013Simons electromagnetic term g_(\u03b1\u03b3) \u2264 2.6 \u00d7 10\u207b\u00b2/H_\u026a, where H_\u026a is the inflationary Hubble parameter, and an amplitude of primordial magnetic fields smoothed over 1 Mpc B_(1Mpc) \u2264 6.6 nG at 95 GHz. We constrain the rms of optical depth fluctuations in a simple \"crinkly surface\" model of patchy reionization, finding A^\u03c4 < 0.19 (2\u03c3) for the coherence scale of L_c = 100. We show that all of the distortion fields of the 95 and 150 GHz polarization maps are consistent with simulations including lensed \u039bCDM, dust, and noise, with no evidence for instrumental systematics. In some cases, the EB and TB quadratic estimators presented here are more sensitive than our previous map-based null tests at identifying and rejecting spurious B-modes that might arise from instrumental effects. Finally, we verify that the standard deprojection filtering in the BICEP/Keck data processing is effective at removing temperature to polarization leakage.", "doi": "10.3847/1538-4357/acc85c", "issn": "0004-637X", "publisher": "American Astronomical Society", "publication": "Astrophysical Journal", "publication_date": "2023-06-01", "series_number": "2", "volume": "949", "issue": "2", "pages": "43" }, { "id": "authors:cd30r-kx285", "collection": "authors", "collection_id": "cd30r-kx285", "cite_using_url": "https://resolver.caltech.edu/CaltechAUTHORS:20230404-289763500.11", "type": "article", "title": "Simultaneous Millimeter-wave, Gamma-Ray, and Optical Monitoring of the Blazar PKS 2326-502 during a Flaring State", "author": [ { "family_name": "Hood", "given_name": "J.

We demonstrate in this work the potential of cosmic microwave background (CMB) telescopes to provide long-term, high-cadence millimeter-wave AGN monitoring over large fractions of sky. We report on a pilot study using data from the SPTpol instrument on the South Pole Telescope (SPT), which was designed to observe the CMB at arcminute and larger angular scales. Between 2013 and 2016, SPTpol was used primarily to observe a single 500 deg\u00b2 field, covering the entire field several times per day with detectors sensitive to radiation in bands centered at 95 and 150 GHz. We use SPT 150 GHz observations to create AGN light curves, and we compare these millimeter-wave light curves to those at other wavelengths, in particular \u03b3-ray and optical. In this Letter, we focus on a single source, PKS 2326-502, which has extensive, day-timescale monitoring data in gamma-ray, optical, and now millimeter-wave between 2013 and 2016. We find PKS 2326-502 to be in a flaring state in the first 2 yr of this monitoring, and we present a search for evidence of correlated variability between millimeter-wave, optical R-band, and \u03b3-ray observations. This pilot study is paving the way for AGN monitoring with current and upcoming CMB experiments such as SPT-3G, Simons Observatory, and CMB-S4, including multiwavelength studies with facilities such as Vera C.

Dust polarization is important for both our understanding of astrophysical processes in the interstellar medium (ISM) and the search for primordial gravitational waves in the cosmic microwave background (CMB). In the diffuse ISM, H i is strongly correlated with the dust and partly organized into filaments that are aligned with the local magnetic field. We analyze the deep BICEP/Keck data at 95, 150, and 220 GHz, over the low-column-density region of sky where BICEP/Keck has set the best limits on primordial gravitational waves. We separate the H i emission into distinct velocity components and detect dust polarization correlated with the local Galactic H i but not with the H i associated with Magellanic Stream i. We present a robust, multifrequency detection of polarized dust emission correlated with the filamentary H i morphology template down to 95 GHz. For assessing its utility for foreground cleaning, we report that the Hi morphology template correlates in B modes at a \u223c10%\u201365% level over the multipole range 20 \u2113 < 200 with the BICEP/Keck maps, which contain contributions from dust, CMB, and noise components. We measure the spectral index of the filamentary dust component spectral energy distribution to be \u03b2 = 1.54 \u00b1 0.13. We find no evidence for decorrelation in this region between the filaments and the rest of the dust field or from the inclusion of dust associated with the intermediate velocity H i. Finally, we explore the morphological parameter space in the H i-based filamentary model.", "doi": "10.3847/1538-4357/acb64c", "issn": "0004-637X", "publisher": "American Astronomical Society", "publication": "Astrophysical Journal", "publication_date": "2023-03-01", "series_number": "1", "volume": "945", "issue": "1", "pages": "Art.

large-scale structure of the Universe. In a forthcoming analysis, we will present cosmological constraints from the analysis of such cross-correlations measured using Year 3 data from the Dark Energy Survey (DES), and CMB data from the South Pole Telescope (SPT) and Planck. Here we present two key ingredients of this analysis: (1) an improved CMB lensing map in the SPT-SZ survey footprint and (2) the analysis methodology that will be used to extract cosmological information from the cross-correlation measurements. Relative to previous lensing maps made from the same CMB observations, we have implemented techniques to remove contamination from the thermal Sunyaev Zel’dovich effect, enabling the extraction of cosmological information from smaller angular scales of the cross-correlation measurements than in previous analyses with DES Year 1 data. We describe our model for the cross-correlations between these maps and DES data, and validate our modeling choices to demonstrate the robustness of our analysis. We then forecast the expected cosmological constraints from the galaxy survey-CMB lensing auto and cross-correlations. We find that the galaxy-CMB lensing and galaxy shear-CMB lensing correlations will on their own provide a constraint on \ud835\udc468=\ud835\udf0e8\u2062√Ωm/0.3 at the few percent level, providing a powerful consistency check for the DES-only constraints. We explore scenarios where external priors on shear calibration are removed, finding that the joint analysis of CMB lensing cross-correlations can provide constraints on the shear calibration amplitude at the 5% to 10% level.

The high signal-to-noise of the CMB lensing cross-correlations enables several powerful consistency tests of these results, including comparisons with constraints derived from cross-correlations only, and comparisons designed to test the robustness of the galaxy lensing and clustering measurements from DES. Applying these tests to our measurements, we find no evidence of significant biases in the baseline cosmological constraints from the DES-only analyses or from the joint analyses with CMB lensing cross-correlations. However, the CMB lensing cross-correlations suggest possible problems with the correlation function measurements using alternative lens galaxy samples, in particular the redmagic galaxies and high-redshift maglim galaxies, consistent with the findings of previous studies. We use the CMB lensing cross-correlations to identify directions for further investigating these problems.

of gravitational lensing of the cosmic microwave background (CMB) are sensitive to the distribution of large-scale structure in the Universe. Such cross-correlations are also expected to be immune to some of the systematic effects that complicate correlation measurements internal to galaxy surveys. We present measurements and modeling of the cross-correlations between galaxy positions and galaxy lensing measured in the first three years of data from the Dark Energy Survey with CMB lensing maps derived from a combination of data from the 2500 deg2 SPT-SZ survey conducted with the South Pole Telescope and full-sky data from the Planck satellite. The CMB lensing maps used in this analysis have been constructed in a way that minimizes biases from the thermal Sunyaev Zel’dovich effect, making them well suited for cross-correlation studies. The total signal-to-noise of the cross-correlation measurements is 23.9 (25.7) when using a choice of angular scales optimized for a linear (nonlinear) galaxy bias model. We use the cross-correlation measurements to obtain constraints on cosmological parameters. For our fiducial galaxy sample, which consist of four bins of magnitude-selected galaxies, we find constraints of Ωm=0.272+0.032−0.052 and \ud835\udc468≡\ud835\udf0e8\u2062√Ωm/0.3=0.736+0.032−0.028 (Ωm=0.245+0.026−0.044 and \ud835\udc468=0.734+0.035−0.028) when assuming linear (nonlinear) galaxy bias in our modeling. Considering only the cross-correlation of galaxy shear with CMB lensing, we find Ωm=0.270+0.043−0.061 and \ud835\udc468=0.740+0.034−0.029. Our constraints on \ud835\udc468 are consistent with recent cosmic shear measurements, but lower than the values preferred by primary CMB measurements from Planck.

We analyze maps of two \u223c270 deg\u00b2 sky regions near the ecliptic plane, each observed with the SPTpol camera \u223c100 times over 1 month. We subtract the mean of all maps of a given field, removing static sky signal, and then average the mean-subtracted maps at known asteroid locations. We detect three asteroids -- (324) Bamberga, (13) Egeria, and (22) Kalliope -- with signal-to-noise ratios (S/N) of 11.2, 10.4, and 6.1, respectively, at 2.0 mm (150 GHz); we also detect (324) Bamberga with an S/N of 4.1 at 3.2 mm (95 GHz). We place constraints on these asteroids' effective emissivities, brightness temperatures, and light-curve modulation amplitude. Our flux density measurements of (324) Bamberga and (13) Egeria roughly agree with predictions, while our measurements of (22) Kalliope suggest lower flux, corresponding to effective emissivities of 0.64 \u00b1 0.11 at 2.0 and < 0.47 at 3.2 mm. We predict the asteroids detectable in other SPT data sets and find good agreement with detections of (772) Tanete and (1093) Freda in recent data from the SPT-3G camera, which has \u223c10\u00d7 the mapping speed of SPTpol. This work is the first focused analysis of asteroids in data from CMB surveys, and it demonstrates we can repurpose historic and future data sets for asteroid studies.

Axion-photon coupling induces a polarization rotation in linearly polarized photons traveling through an ALP field; thus, as the local ALP dark matter field oscillates in time, distant static polarized sources will appear to oscillate with a frequency proportional to the ALP mass. We use observations of the cosmic microwave background from SPT-3G, the current receiver on the South Pole Telescope, to set upper limits on the value of the axion-photon coupling constant g_(\u03d5\u03b3) over the approximate mass range \n10\u207b\u00b2\u00b2-10\u207b\u00b9\u2079 eV, corresponding to oscillation periods from 12 hours to 100 days.

It started science observation at the South Pole in 2016 with 2400 antenna-coupled transition-edge sensor bolometers. The receiver first demonstrated new technologies such as large-diameter alumina optics, Zotefoam infrared filters, and flux-activated SQUIDs, allowing \u223c10\u00d7 higher optical throughput compared to the Keck design. Bicep3 achieved instrument noise equivalent temperatures of 9.2, 6.8, and 7.1 \u03bcK_(CMB) \u221as and reached Stokes Q and U map depths of 5.9, 4.4, and 4.4 \u03bcK arcmin in 2016, 2017, and 2018, respectively.

Sensitive measurements of the temperature and polarization anisotropies of the CMB provide a powerful data set for constraining cosmology. Additionally, CMB surveys with arcminute-scale resolution are capable of detecting galaxy clusters, millimeter-wave bright galaxies, and a variety of transient phenomena. The SPT-3G instrument provides a significant improvement in mapping speed over its predecessors, SPT-SZ and SPTpol. The broadband optics design of the instrument achieves a 430 mm diameter image plane across observing bands of 95, 150, and 220 GHz, with 1.2\u2032 FWHM beam response at 150 GHz. In the receiver, this image plane is populated with 2690 dual-polarization, trichroic pixels (\u223c16,000 detectors) read out using a 68\u00d7 digital frequency-domain multiplexing readout system. In 2018, SPT-3G began a multiyear survey of 1500 deg\u00b2 of the southern sky.

An all-sky, temporally sinusoidal rotation of CMB polarization, equivalent to a time-variable cosmic birefringence, is an observable manifestation of a local axion field and potentially allows a CMB polarimeter to detect axionlike dark matter directly. We describe improvements to the method presented in previous work, and we demonstrate the updated method with an expanded dataset consisting of the 2012\u20132015 observing seasons. We set limits on the axion-photon coupling constant for mass m in the range 10\u207b\u00b2\u00b3\u201310\u207b\u00b9\u2078 eV, which corresponds to oscillation periods on the order of hours to years. Our results are consistent with the background model. For periods between 1 and 30 d (1.6 \u00d7 10\u207b\u00b2\u00b9 \u2264 m \u2264 4.8 \u00d7 10\u207b\u00b2\u2070 eV), the 95%-confidence upper limits on rotation amplitude are approximately constant with a median of 0.27\u00b0, which constrains the axion-photon coupling constant to g_(\u03d5\u03b3) < (4.5 \u00d7 10\u207b\u00b9\u00b2 GeV\u207b\u00b9)m/(10\u207b\u00b2\u00b9 eV), if axionlike particles constitute all of the dark matter. More than half of the collected BICEP dataset has yet to be analyzed, and several current and future CMB polarimetry experiments can apply the methods presented here to achieve comparable or superior constraints.

The technology used to read out and control these detectors, digital frequency-domain multiplexing (DfMUX), is conceptually the same as used for SPTpol, but extended to accommodate more detectors. A nearly 5\u00d7 expansion in the readout operating bandwidth has enabled the use of this large focal plane, and SPT-3G performance meets the forecasting targets relevant to its science objectives. However, the electrical dynamics of the higher-bandwidth readout differ from predictions based on models of the SPTpol system due to the higher frequencies used and parasitic impedances associated with new cryogenic electronic architecture. To address this, we present an updated derivation for electrical crosstalk in higher-bandwidth DfMUX systems and identify two previously uncharacterized contributions to readout noise, which become dominant at high bias frequency. The updated crosstalk and noise models successfully describe the measured crosstalk and readout noise performance of SPT-3G. These results also suggest specific changes to warm electronics component values, wire-harness properties, and SQUID parameters, to improve the readout system for future experiments using DfMUX, such as the LiteBIRD space telescope.", "doi": "10.1117/1.JATIS.8.1.014001", "issn": "2329-4221", "publisher": "Society of Photo-optical Instrumentation Engineers", "publication": "Journal of Astronomical Telescopes, Instruments, and Systems", "publication_date": "2022-01", "series_number": "1", "volume": "8", "issue": "1", "pages": "Art.

These data reach noise levels as low as 5.8 \u03bcK arcmin in polarization, which are low enough that the typically used quadratic estimator (QE) technique for analyzing CMB lensing is significantly suboptimal. Conversely, the Bayesian procedure extracts all lensing information from the data and is optimal at any noise level. We infer the amplitude of the gravitational lensing potential to be A_\u03d5 = 0.949 \u00b1 0.122 using the Bayesian pipeline, consistent with our QE pipeline result, but with 17% smaller error bars. The Bayesian analysis also provides a simple way to account for systematic uncertainties, performing a similar job as frequentist \"bias hardening\" or linear bias correction, and reducing the systematic uncertainty on A_\u03d5\ndue to polarization calibration from almost half of the statistical error to effectively zero. Finally, we jointly constrain A_\u03d5 along with A_L, the amplitude of lensing-like effects on the CMB power spectra, demonstrating that the Bayesian method can be used to easily infer parameters both from an optimal lensing reconstruction and from the delensed CMB, while exactly accounting for the correlation between the two. These results demonstrate the feasibility of the Bayesian approach on real data, and pave the way for future analysis of deep CMB polarization measurements with SPT-3G, Simons Observatory, and CMB-S4, where improvements relative to the QE can reach 1.5 times tighter constraints on A_\u03d5 and seven times lower effective lensing reconstruction noise.", "doi": "10.3847/1538-4357/ac02bb", "issn": "0004-637X", "publisher": "American Astronomical Society", "publication": "Astrophysical Journal", "publication_date": "2021-12-01", "series_number": "2", "volume": "922", "issue": "2", "pages": "Art.

The 220 GHz maps now achieve a signal-to-noise ratio on polarized dust emission exceeding that of Planck at 353 GHz. We take auto- and cross-spectra between these maps and publicly available WMAP and Planck maps at frequencies from 23 to 353 GHz and evaluate the joint likelihood of the spectra versus a multicomponent model of lensed \u039bCDM + r + dust + synchrotron + noise. The foreground model has seven parameters, and no longer requires a prior on the frequency spectral index of the dust emission taken from measurements on other regions of the sky. This model is an adequate description of the data at the current noise levels. The likelihood analysis yields the constraint r_(0.05) < 0.036 at 95% confidence.

Here we report the first results of an astronomical transient survey with the South Pole Telescope (SPT) using the SPT-3G camera to observe 1500 deg\u00b2 of the southern sky. The observations took place from 2020 March to November in three bands centered at 95, 150, and 220 GHz. This survey yielded the detection of 15 transient events from sources not previously detected by the SPT. The majority are associated with variable stars of different types, expanding the number of such detected flares by more than a factor of two. The stellar flares are unpolarized and bright, in some cases exceeding 1 Jy, and have durations from a few minutes to several hours. Another population of detected events last for 2\u20133 weeks and appear to be extragalactic in origin. Though data availability at other wavelengths is limited, we find evidence for concurrent optical activity for two of the stellar flares. Future data from SPT-3G and forthcoming instruments will provide real-time detection of millimeter-wave transients on timescales of minutes to months.", "doi": "10.3847/1538-4357/ac06a3", "issn": "0004-637X", "publisher": "American Astronomical Society", "publication": "Astrophysical Journal", "publication_date": "2021-08-01", "series_number": "2", "volume": "916", "issue": "2", "pages": "Art.

"We present measurements of the E-mode (EE) polarization power spectrum and temperature-E-mode (TE) cross-power spectrum of the cosmic microwave background using data collected by SPT-3G, the latest instrument installed on the South Pole Telescope. This analysis uses observations of a 1500\u2009deg\u00b2 region at 95, 150, and 220 GHz taken over a four-month period in 2018. We report binned values of the EE and TE power spectra over the angular multipole range 300 \u2264 \u2113 < 3000, using the multifrequency data to construct six semi-independent estimates of each power spectrum and their minimum-variance combination. These measurements improve upon the previous results of SPTpol across the multipole ranges 300 \u2264 \u2113 \u2264 1400 for EE and 300 \u2264 \u2113 \u2264 1700 for TE, resulting in constraints on cosmological parameters comparable to those from other current leading ground-based experiments. We find that the SPT-3G data set is well fit by a \u039bCDM cosmological model with parameter constraints consistent with those from Planck and SPTpol data. From SPT-3G data alone, we find H\u2080 = 68.8\u00b11.5\u2009\u2009km\u2009s\u207b\u00b9\u2009Mpc\u207b\u00b9 and \u03c3\u2088 = 0.789\u00b10.016, with a gravitational lensing amplitude consistent with the \u039bCDM prediction (A_L = 0.98\u00b10.12). We combine the SPT-3G and the Planck data sets and obtain joint constraints on the \u039bCDM model. The volume of the 68% confidence region in six-dimensional \u039bCDM parameter space is reduced by a factor of 1.5 compared to Planck-only constraints, with no significant shifts in central values. We note that the results presented here are obtained from data collected during just half of a typical observing season with only part of the focal plane operable, and that the active detector count has since nearly doubled for observations made with SPT-3G after 2018.", "doi": "10.1103/physrevd.104.022003", "issn": "2470-0010", "publisher": "American Physical Society", "publication": "Physical Review D", "publication_date": "2021-07-15", "series_number": "2", "volume": "104", "issue": "2", "pages": "Art.

By adding 95 and 150 GHz data from the low-noise 500 deg\u00b2 SPTpol survey to the SPT-SZ three-frequency 2540 deg\u00b2 survey, we substantially reduce the uncertainties in these bands. These power spectra include contributions from the primary cosmic microwave background, cosmic infrared background, radio galaxies, and thermal and kinematic Sunyaev\u2013Zel'dovich (SZ) effects. The data favor a thermal SZ (tSZ) power at 143 GHz of D^(tSZ)\u2083\u2080\u2080\u2080 = 3.42\u00b10.54 \u03bcK\u00b2 and a kinematic SZ (kSZ) power of D^(kSZ)\u2083\u2080\u2080\u2080 = 3.0 \u00b1 1.0 \u03bcK\u00b2. This is the first measurement of kSZ power at \u22653\u03c3. However, different assumptions about the CIB or SZ models can reduce the significance down to 2.4\u03c3 in the worst case. We study the implications of the measured kSZ power for the epoch of reionization under the Calabrese et al. model for the kSZ power spectrum and find the duration of reionization to be \u0394z_(re) = 1.1^(+1.6)_(\u22120.7) (\u0394z_(re) < 4.1 at 95% confidence), when combined with our previously published tSZ bispectrum measurement. The upper limit tightens to \u0394z_(re) < 3.2 if the assumed homogeneous kSZ power is increased by 25% (~0.5 \u03bcK\u00b2) and relaxes to \u0394z_(re) < 5.2 if the homogeneous kSZ power is decreased by the same amount.", "doi": "10.3847/1538-4357/abd407", "issn": "1538-4357", "publisher": "American Astronomical Society", "publication": "Astrophysical Journal", "publication_date": "2021-02-20", "series_number": "2", "volume": "908", "issue": "2", "pages": "Art.

A local axion field induces an all-sky, temporally sinusoidal rotation of CMB polarization. A CMB polarimeter can thus function as a direct-detection experiment for axionlike dark matter. We develop techniques to extract an oscillation signal. Many elements of the method are generic to CMB polarimetry experiments and can be adapted for other datasets. As a first demonstration, we process data from the 2012 observing season to set upper limits on the axion-photon coupling constant in the mass range 10\u207b\u00b2\u00b9\u201310\u207b\u00b9\u2078\u2009eV, which corresponds to oscillation periods on the order of hours to months. We find no statistically significant deviations from the background model. For periods larger than 24 hr (mass m < 4 .8\u00d710\u207b\u00b2\u2070\u2009\u2009eV), the median 95% confidence upper limit is equivalent to a rotation amplitude of 0.68\u00b0, which constrains the axion-photon coupling constant to g_(\u03d5\u03b3) < (1.1\u00d710\u207b\u00b9\u00b9\u2009GeV\u207b\u00b9)m/(10\u207b\u00b2\u00b9\u2009eV), if axionlike particles constitute all of the dark matter. The constraints can be improved substantially with data already collected by the BICEP series of experiments.

This template is constructed by combining an estimate of the polarized CMB with a tracer of the projected large-scale structure. The large-scale-structure tracer used is a map of the cosmic infrared background derived from Planck satellite data, while the polarized CMB map comes from a combination of South Pole Telescope, BICEP/Keck, and Planck data. We expand the BICEP/Keck likelihood analysis framework to accept a lensing template and apply it to the BICEP/Keck dataset collected through 2014 using the same parametric foreground modeling as in the previous analysis. From simulations, we find that the uncertainty on r is reduced by \u223c10%, from \u03c3(r) = 0.024 to 0.022, which can be compared with a \u223c26% reduction obtained when using a perfect lensing template or if there were zero lensing B-modes. Applying the technique to the real data, the constraint on r is improved from r_(0.05) < 0.090 to r_(0.05) < 0.082 (95% C.L.). This is the first demonstration of improvement in an r constraint through delensing.", "doi": "10.1103/physrevd.103.022004", "issn": "2470-0010", "publisher": "American Physical Society", "publication": "Physical Review D", "publication_date": "2021-01-15", "series_number": "2", "volume": "103", "issue": "2", "pages": "Art.

This work uses 500 deg\u00b2 of SPTpol data, a five-fold increase over the last SPTpol B-mode release. As a result, the bandpower uncertainties have been reduced by more than a factor of two, and the measurement extends to lower multipoles: 52 < \u2113 < 2301.

This B-mode signal arises from primordial gravitational waves interacting with the CMB and has amplitude parametrized by the tensor-to-scalar ratio r. Since 2016, BICEP3 and the Keck Array have been observing with 4800 total antenna-coupled transition-edge sensor detectors, with frequency bands spanning 95, 150, 220, and 270 GHz. Here we present the optical performance of these receivers from 2016 to 2019, including far-field beams measured in situ with an improved chopped thermal source and instrument spectral response measured with a field-deployable Fourier transform spectrometer. As a pair differencing experiment, an important systematic that must be controlled is the differential beam response between the co-located, orthogonally polarized detectors. We generate per-detector far-field beam maps and the corresponding differential beam mismatch that is used to estimate the temperature-to-polarization leakage in our CMB maps and to give feedback on detector and optics fabrication. The differential beam parameters presented here were estimated using improved low-level beam map analysis techniques, including efficient removal of non-Gaussian noise as well as improved spatial masking. These techniques help minimize systematic uncertainty in the beam analysis, with the goal of constraining the bias on r induced by temperature-to-polarization leakage to be subdominant to the statistical uncertainty. This is essential as we progress to higher detector counts in the next generation of CMB experiments.", "doi": "10.1007/s10909-020-02392-8", "issn": "0022-2291", "publisher": "Springer", "publication": "Journal of Low Temperature Physics", "publication_date": "2020-05", "series_number": "3-4", "volume": "199", "issue": "3-4", "pages": "824-832" }, { "id": "authors:mp2rp-1z284", "collection": "authors", "collection_id": "mp2rp-1z284", "cite_using_url": "https://resolver.caltech.edu/CaltechAUTHORS:20200225-082326440", "type": "article", "title": "Characterizing the Sensitivity of 40 GHz TES Bolometers for BICEP Array", "author": [ { "family_name": "Zhang", "given_name": "C.", "orcid": "0000-0001-8288-5823", "clpid": "Zhang-Cheng" }, { "family_name": "Ade", "given_name": "P.

Clusters are identified via the Sunyaev\u2013Zel'dovich (SZ) effect and confirmed with a combination of archival and targeted follow-up data, making particular use of data from the Dark Energy Survey (DES). With incomplete follow-up we have confirmed as clusters 244 of 266 candidates at a detection significance \u03be \u2265 5 and an additional 204 systems at 4 < \u03be < 5.

Radio data are used to characterize contamination to the SZ signal; the median contamination for confirmed clusters is predicted to be ~1% of the SZ signal at the \u03be > 4 threshold, and <4% of clusters have a predicted contamination >10% of their measured SZ flux. We associate SZ-selected clusters, from both SPT-ECS and the SPT-SZ survey, with clusters from the DES redMaPPer sample, and we find an offset distribution between the SZ center and central galaxy in general agreement with previous work, though with a larger fraction of clusters with significant offsets. Adopting a fixed Planck-like cosmology, we measure the optical richness\u2013SZ mass (\u03bb\u2212M) relation and find it to be 28% shallower than that from a weak-lensing analysis of the DES data\u2014a difference significant at the 4\u03c3 level\u2014with the relations intersecting at \u03bb = 60.

The lensing potential is reconstructed with signal-to-noise per mode greater than unity at lensing multipoles L \u227e 250, using a quadratic estimator on a combination of cosmic microwave background temperature and polarization maps. We report measurements of the lensing potential power spectrum in the multipole range of 100 < L < 2000 from sets of temperature-only (T), polarization-only (POL), and minimum-variance (MV) estimators. We measure the lensing amplitude by taking the ratio of the measured spectrum to the expected spectrum from the best-fit \u039b cold dark matter model to the Planck 2015 TT + low P + lensing data set. For the minimum-variance estimator, we find A_(MV) = 0.944\u00b10.058(Stat.)\u00b10.025(Sys.) restricting to only polarization data, we find A_(POL) = 0.906\u00b10.090(Stat.)\u00b10.040(Sys.). Considering statistical uncertainties alone, this is the most precise polarization-only lensing amplitude constraint to date (10.1\u03c3) and is more precise than our temperature-only constraint.
