The Simons Observatory: Detector Polarization Angle Calibration using Sparse Wire Grid with Initial Data Sets of the Small Aperture Telescope
Hironobu Nakata, Shunsuke Adachi, Kyohei Yamada +22
Improved measurements of -modes in the cosmic microwave background can be obtained through accurate calibration of the orientation of detector antennas as projected onto the sky…
Constraints on the polarization angle oscillations of the Crab Nebula with the Simons Array and its applications to the search for axion-like particles
Tylor Adkins, Shahed Shayan Arani, Kam Arnold +27
We present a search for polarization oscillation of the Crab Nebula, also known as Tau A, at millimeter wavelengths using observations with the Simons Array, the successor experime…
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,…
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: 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…
