A path towards CMB spectral distortion measurements

Bruno Maffei, Nabila Aghanim, Valentin Sauvage, Morgane Loquet Le Gall et autres

The only detailed measurement of the cosmic microwave background (CMB) spectrum, by COBE-FIRAS in the early 90s, showed that it is close to perfect blackbody emission. However, theory predicts that small deviations, referred to as CMB spectral distortions, are expected, but, due …

Optical modeling for the LiteBIRD Medium and High Frequency Telescope

Luca Lamagna, C. Franceschet, M. De Petris, Peter Hargrave et autres

LiteBIRD is the next-generation space mission for polarization-sensitive mapping of the Cosmic Microwave Background anisotropies, with observations covering the full sky in a wide frequency range (34-448 GHz) to ensure high-precision removal of polarized foregrounds. Its main goal is to constrain the …

LiteBIRD satellite: JAXA's new strategic L-class mission for all-sky surveys of cosmic microwave background polarization

M. Hazumi, Peter A. R. Ade, Alexandre Adler, Erwan Allys et autres

LiteBIRD, the Lite (Light) satellite for the study of B-mode polarization and Inflation from cosmic background Radiation Detection, is a space mission for primordial cosmology and fundamental physics. JAXA selected LiteBIRD in May 2019 as a strategic large-class (L-class) mission, with its …
