Polarization Angle Swings in Blazars Detected in the Millimeter-wave with the South Pole Telescope

A. Simpson, E. Anderes, A. J. Anderson +93

We present the first systematic search for electric vector position angle (EVPA) swings in the millimeter-wave (mm-wave) emission of blazars, using five years of observations from…

The Atacama Cosmology Telescope: A Test of the Gravitational Force Law on Cosmological Scales Using the Kinematic Sunyaev-Zeldovich Effect

Patricio A. Gallardo, Kris Pardo, Oliver H. E. Philcox +38

The mean pairwise velocity of massive halos reflects the gravitational force law on cosmic scales. We combine cosmic microwave background intensity maps from the Atacama Cosmology…

The Atacama Cosmology Telescope: DR6 Sunyaev-Zel'dovich Selected Galaxy Clusters Catalog

HSC Collaboration, M. Aguena, S. Aiola +98

We present the results of a search for galaxy clusters in the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) microwave sky maps covering 16293 square degrees in three frequ…

A high-dynamic-range view of the growth of structure and the warm/hot Universe

Luca Di Mascolo, Tony Mroczkowski, Joshiwa van Marrewijk +23

Baryons heat to temperatures above as they accrete onto massive overdensities -- galaxies, groups, clusters, and filaments -- where they ionize and become o…

The Atacama Cosmology Telescope: A Measurement of the DR6 CMB Lensing Power Spectrum and its Implications for Structure Growth

Frank J. Qu, Blake D. Sherwin, Mathew S. Madhavacheril +155

We present new measurements of cosmic microwave background (CMB) lensing over sq. deg. of the sky. These lensing measurements are derived from the Atacama Cosmology Telescop…

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,…
