Map Multi-Tool: A Map-Based Approach to Modeling Beam Systematics for Cosmic Microwave Background Experiments
Cesiley L. King, Alec Hryciuk, Jeff McMahon +2
Cosmic microwave background (CMB) experiments use simulations of instrumental systematic effects to ensure high-fidelity measurements of cosmological parameters. Quantifying the ex…
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 Constraints on Extended Cosmological Models
Erminia Calabrese, J. Colin Hill, Hidde T. Jense +169
We use new cosmic microwave background (CMB) primary temperature and polarization anisotropy measurements from the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) to test fo…
The Atacama Cosmology Telescope: DR6 Power Spectra, Likelihoods and CDM Parameters
Thibaut Louis, Adrien La Posta, Zachary Atkins +165
We present power spectra of the cosmic microwave background (CMB) anisotropy in temperature and polarization, measured from the Data Release 6 maps made from Atacama Cosmology Tele…
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…
The Atacama Cosmology Telescope: DR6 Maps
Sigurd Naess, Yilun Guan, Adriaan J. Duivenvoorden +163
We present Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) maps of the Cosmic Microwave Background temperature and polarization anisotropy at arcminute resolution over three…
