Combining Planck and SPT cluster catalogs: cosmological analysis and impact on Planck scaling relation calibration
L. Salvati, A. Saro, S. Bocquet +41
We provide the first combined cosmological analysis of South Pole Telescope (SPT) and Planck cluster catalogs. The aim is to provide an independent calibration for Planck scaling r…
Improving cosmological constraints from galaxy cluster number counts with CMB-cluster-lensing data: Results from the SPT-SZ survey and forecasts for the future
P. S. Chaubal, C. L. Reichardt, N. Gupta +40
We show the improvement to cosmological constraints from galaxy cluster surveys with the addition of CMB-cluster lensing data. We explore the cosmological implications of adding ma…
Synthesizing Stellar Populations in South Pole Telescope Galaxy Clusters: I. Ages of Quiescent Member Galaxies at 0.3 < z < 1.4
Gourav Khullar, Matthew B. Bayliss, Michael D. Gladders +14
Using stellar population synthesis models to infer star formation histories (SFHs), we analyse photometry and spectroscopy of a large sample of quiescent galaxies which are members…
Shocks in the Stacked Sunyaev-Zel'dovich Profiles of Clusters II: Measurements from SPT-SZ + Planck Compton-y Map
D. Anbajagane, C. Chang, B. Jain +43
We search for the signature of cosmological shocks in stacked gas pressure profiles of galaxy clusters using data from the South Pole Telescope (SPT). Specifically, we stack the la…
The Parameter-Level Performance of Covariance Matrix Conditioning in Cosmic Microwave Background Data Analyses
L. Balkenhol, C. L. Reichardt
Empirical estimates of the band power covariance matrix are commonly used in cosmic microwave background (CMB) power spectrum analyses. While this approach easily captures correlat…
Constraining Cluster Virialization Mechanism and Cosmology using Thermal-SZ-selected clusters from Future CMB Surveys
Srinivasan Raghunathan, Nathan Whitehorn, Marcelo A. Alvarez +7
We forecast the number of galaxy clusters that can be detected via the thermal Sunyaev-Zeldovich (tSZ) signals by future cosmic microwave background (CMB) experiments, primarily th…
The Design and Integrated Performance of SPT-3G
J. A. Sobrin, A. J. Anderson, A. N. Bender +120
SPT-3G is the third survey receiver operating on the South Pole Telescope dedicated to high-resolution observations of the cosmic microwave background (CMB). Sensitive measurements…
Constraints on CDM Extensions from the SPT-3G 2018 and Power Spectra
L. Balkenhol, D. Dutcher, P. A. R. Ade +117
We present constraints on extensions to the CDM cosmological model from measurements of the -mode polarization auto-power spectrum and the temperature--mode cross-power sp…
Performance and characterization of the SPT-3G digital frequency-domain multiplexed readout system using an improved noise and crosstalk model
J. Montgomery, P. A. R. Ade, Z. Ahmed +118
The third generation South Pole Telescope camera (SPT-3G) improves upon its predecessor (SPTpol) by an order of magnitude increase in detectors on the focal plane. The technology u…
Detection of Galactic and Extragalactic Millimeter-Wavelength Transient Sources with SPT-3G
S. Guns, A. Foster, C. Daley +119
High-angular-resolution cosmic microwave background experiments provide a unique opportunity to conduct a survey of time-variable sources at millimeter wavelengths, a population wh…
CMB/kSZ and Compton- Maps from 2500 square degrees of SPT-SZ and Planck Survey Data
L. E. Bleem, T. M. Crawford, B. Ansarinejad +37
We present component-separated maps of the primary cosmic microwave background/kinematic Sunyaev-Zel'dovich (SZ) amplitude and the thermal SZ Compton- parameter, created using d…
Simons Observatory Small Aperture Telescope overview
Kenji Kiuchi, Shunsuke Adachi, Aamir M. Ali +51
The Simons Observatory (SO) is a cosmic microwave background (CMB) experiment from the Atacama Desert in Chile comprising three small-aperture telescopes (SATs) and one large-apert…
