The Simons Observatory: forecasted constraints on primordial gravitational waves with the expanded array of Small Aperture Telescopes

The Simons Observatory Collaboration, I. Abril-Cabezas, S. Adachi +479

We present updated forecasts for the scientific performance of the degree-scale (0.5 deg FWHM at 93 GHz), deep-field survey to be conducted by the Simons Observatory (SO). By 2027,…

Demonstration of a 1820 channel multiplexer for transition-edge sensor bolometers

J. C. Groh, Z. Ahmed, J. Austermann +16

The scalability of most transition-edge sensor arrays is limited by the multiplexing technology which combines their signals over a reduced number of wires and amplifiers. In this…

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,…

The Simons Observatory: Science Goals and Forecasts for the Enhanced Large Aperture Telescope

The Simons Observatory Collaboration, M. Abitbol, I. Abril-Cabezas +419

We describe updated scientific goals for the wide-field, millimeter-wave survey that will be produced by the Simons Observatory (SO). Significant upgrades to the 6-meter SO Large A…

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…
