The Atacama Cosmology Telescope: stellar mass growth in massive galaxy clusters from DR5 over the past 7 billion years
Damien C. Ragavan, Unnikrishnan Sureshkumar, Matt Hilton +8
We probe the stellar mass growth in a sample of 568 Sunyaev-Zel'dovich (SZ) selected galaxy clusters with masses greater than and redshifts…
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…
Broadband Optical Modulation and Control at Millikelvin Temperatures
N. Tabassum, T. Aralis, J. Anczarski +17
A universal experimental challenge when studying radiation effects on cryogenic devices is to precisely and accurately characterize the position-dependent device response very near…
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…
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: Quantifying Atmospheric Emission above Cerro Toco
Thomas W. Morris, Elia Battistelli, Ricardo Bustos +17
At frequencies below 1 Hz, fluctuations in atmospheric emission in the Chajnantor region in northern Chile are the primary source of interference for bolometric millimeter-wave obs…
