The polarization of the cosmic microwave background (CMB) can be used to search for
parity-violating processes like that predicted by a Chern-Simons coupling to a light …

The change of physical conditions across the turbulent and magnetized interstellar medium
induces a 3D spatial variation of the properties of Galactic polarized emission. The observed …

The Simons Observatory (SO), due to start full science operations in early 2025, aims to set
tight constraints on inflationary physics by inferring the tensor-to-scalar ratio r from …

LiteBIRD is a planned JAXA-led cosmic microwave background (CMB) B-mode satellite
experiment aiming for launch in the late 2020s, with a primary goal of detecting the imprint of …

ABSTRACT A key challenge in the search for primordial B-modes is the presence of
polarized Galactic foregrounds, especially thermal dust emission. Power-spectrum-based …

The quest for primordial B-modes in the cosmic microwave background has emphasized the
need for refined models of the Galactic dust foreground. Here we aim at building a realistic …

The observation of the polarised emission from the Cosmic Microwave Background (CMB)
from future ground-based and satellite-borne experiments holds the promise of indirectly …

Galaxy clusters detected through the thermal Sunyaev–Zeldovich (tSZ) effect are a powerful
cosmological probe from which constraints on cosmological parameters such as Ωm and σ8 …

Context. The upcoming Simons Observatory Small Aperture Telescopes aim at achieving a
constraint on the primordial tensor-to-scalar ratio r at the level of σ (r= 0)≲ 0.003, observing …

Abstract Upcoming Cosmic Microwave Background (CMB) experiments, aimed at measuring
