Sensitivity of Next-Generation CMB Surveys to Neutrinos and Other Light Relics

Cynthia Trendafilova, Srinivasan Raghunathan, Benjamin Wallisch +33

Neutrinos and other light relics leave characteristic imprints in the cosmic microwave background anisotropies, making their observation a sensitive probe of the particle content a…

LiteBIRD Mission Overview after Mission Reformation

LiteBIRD Collaboration, K. Aizawa, H. Akamatsu +172

LiteBIRD is a JAXA-led space mission designed to produce all-sky microwave polarization maps. Its primary science goal is to test representative inflationary models by measuring th…

The Simons Observatory: Validation of reconstructed power spectra from simulated filtered maps for the Small Aperture Telescope survey

Carlos Hervías-Caimapo, Kevin Wolz, Adrien La Posta +33

We present a transfer function-based method to estimate angular power spectra from filtered maps for cosmic microwave background (CMB) surveys. This is especially relevant for expe…
