A GPU-Accelerated JAX Framework for Robust Parametric Component Separation and Clustering Optimization for CMB Polarization Satellites

Wassim Kabalan, A. Rizzieri, Wuhyun Sohn, A. Basyrov et autres

We present a novel, JAX-powered implementation of a parametric component-separation method for CMB polarization data, explicitly designed to handle spatially varying foreground Spectral Energy Distributions (SEDs). The approach models this variation across the sky by grouping sets of pixels that share common …

The Simons Observatory: forecasted constraints on primordial gravitational waves with the expanded array of Small Aperture Telescopes

Irene Abril-Cabezas, S. Adachi, P. Ade, Alexandre Adler et autres

Abstract 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 SO Small Aperture Telescope (SAT) complement will be doubled from three …

The Atacama Cosmology Telescope: DR6 power spectra, likelihoods and ΛCDM parameters

Thibaut Louis, Adrien La Posta, Zachary Atkins, Hidde T. Jense et autres

Abstract 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 Telescope (ACT) data. These cover 19,000 deg 2 of sky in bands centered at 98, …

The Atacama Cosmology Telescope: DR6 power spectrum foreground model and validation

Benjamin Beringue, Kristen M. Surrao, J. Colin Hill, Zachary Atkins et autres

Abstract We discuss the model of astrophysical emission at millimeter wavelengths used to characterize foregrounds in the multi-frequency power spectra of the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6), expanding on Louis et al. (2025) ( 2503.14452 ). We detail several …

The Simons Observatory: science goals and forecasts for the enhanced Large Aperture Telescope

M. Abitbol, Irene Abril-Cabezas, S. Adachi, P. A. R. Ade et autres

Abstract 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 Aperture Telescope (LAT) are expected to be complete by 2028, and will include a doubled …

The Atacama Cosmology Telescope: DR6 Constraints on Extended Cosmological Models

Erminia Calabrese, J. Colin Hill, Hidde T. Jense, Adrien La Posta et autres

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 foundational assumptions of the standard cosmological model and set constraints on extensions to it. We derive constraints …
