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 Atacama Cosmology Telescope DR6 and DESI: Structure formation over cosmic time with a measurement of the cross-correlation of CMB Lensing and Luminous Red Galaxies

Joshua Kim, Noah Sailer, Mathew S. Madhavacheril +70

We present a high-significance cross-correlation of CMB lensing maps from the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) with spectroscopically calibrated luminous red…

The Atacama Cosmology Telescope: A search for late-time anisotropic screening of the Cosmic Microwave Background

William R. Coulton, Theo Schutt, Abhishek S. Maniyar +37

Since the formation of the first stars, most of the gas in the Universe has been ionized. Spatial variations in the density of this ionized gas generate cosmic microwave background…

Cosmological constraints from the cross-correlation of DESI Luminous Red Galaxies with CMB lensing from Planck PR4 and ACT DR6

Noah Sailer, Joshua Kim, Simone Ferraro +63

We infer the growth of large scale structure over the redshift range from the cross-correlation of spectroscopically calibrated Luminous Red Galaxies (LR…

The Atacama Cosmology Telescope: Systematic Transient Search of Single Observation Maps

Emily K. Biermann, Yaqiong Li, Sigurd Naess +24

We conduct a systematic search for astrophysical transients using data from the Atacama Cosmology Telescope (ACT). The data were taken from 2017 to 2022 in three frequency bands sp…

The Atacama Cosmology Telescope: DR6 Gravitational Lensing and SDSS BOSS cross-correlation measurement and constraints on gravity with the statistic

Lukas Wenzl, Rui An, Nick Battaglia +24

We derive new constraints on the statistic as a test of gravity, combining the CMB lensing map estimated from Data Release 6 (DR6) of the Atacama Cosmology Telescope with SDS…
