The SPT-Deep Cluster Catalog: Sunyaev-Zel'dovich Selected Clusters from Combined SPT-3G and SPTpol Measurements over 100 Square Degrees

K. Kornoelje, L. E. Bleem, E. S. Rykoff +191

We present a catalog of 500 galaxy cluster candidates in the SPT-Deep field: a 100 deg field that combines data from the SPT-3G and SPTpol surveys to reach noise levels of 3.0,…

Measurements of the Temperature and E-mode Polarization of the Cosmic Microwave Background from the Full 500-square-degree SPTpol Dataset

T. -L. Chou, P. A. R. Ade, A. J. Anderson +59

Using the full four-year SPTpol 500 deg dataset in both the 95 GHz and 150 GHz frequency bands, we present measurements of the temperature and -mode polarization of the cosm…

Multiprobe Cosmology from the Abundance of SPT Clusters and DES Galaxy Clustering and Weak Lensing

S. Bocquet, S. Grandis, E. Krause +216

Cosmic shear, galaxy clustering, and the abundance of massive halos each probe the large-scale structure of the Universe in complementary ways. We present cosmological constraints…

Cosmology From CMB Lensing and Delensed EE Power Spectra Using 2019-2020 SPT-3G Polarization Data

F. Ge, M. Millea, E. Camphuis +93

From CMB polarization data alone we reconstruct the CMB lensing power spectrum, comparable in overall constraining power to previous temperature-based reconstructions, and an unlen…

Mass calibration of DES Year-3 clusters via SPT-3G CMB cluster lensing

B. Ansarinejad, S. Raghunathan, T. M. C. Abbott +142

We measure the stacked lensing signal in the direction of galaxy clusters in the Dark Energy Survey Year 3 (DES Y3) redMaPPer sample, using cosmic microwave background (CMB) temper…

Testing the CDM Cosmological Model with Forthcoming Measurements of the Cosmic Microwave Background with SPT-3G

K. Prabhu, S. Raghunathan, M. Millea +98

We forecast constraints on cosmological parameters enabled by three surveys conducted with SPT-3G, the third-generation camera on the South Pole Telescope. The surveys cover separa…
