Mitigating half-wave plate systematics at the map-making level: calibration requirements for LiteBIRD

N. Raffuzzi, A. Carones, M. Monelli, S. Giardiello et autres

Abstract Although half-wave plates (HWPs) are becoming a popular choice of polarization modulators for cosmic microwave background (CMB) experiments, their non-idealities can introduce systematic effects that should be carefully characterized and mitigated. One possible mitigation strategy is to incorporate information about the …

LiteBIRD Mission Overview after Mission Reformation

LiteBIRD Collaboration, K. Aizawa, H. Akamatsu, R. Akizawa et autres

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 the cosmic microwave background $B$-mode polarization generated by primordial gravitational waves, while also providing new insights into …

Galactic Science with the LiteBIRD satellite: Spectral characterization of diffuse Galactic polarized emission at the angular power spectrum level

S. Vinzl, J. Aumont, L. Vacher, R. T. Génova-Santos et autres

Detection of primordial $B$-mode polarization in the cosmic microwave background (CMB) from tensor perturbations generated during inflation is a major scientific goal of future CMB missions. Its success will strongly depend on the characterization of polarized foregrounds, a challenge that the LiteBIRD …

A cross-calibration approach for polarisation-sensitive detectors in CMB experiments: application to LiteBIRD's polarisation angle calibration

A. Novelli, F Piacentini, S. Micheli, E. Allys et autres

One of the current challenges in observational cosmology is obtaining high-precision polarisation maps of the CMB to measure primordial $B$-modes and constrain the tensor-to-scalar ratio ($r$). The weakness of this signal compared to foregrounds and $E$-to-$B$ leakage makes this task particularly challenging, …

JWST imaging of the Pleiades: Anisotropy of turbulence in the cold neutral medium

G. Vigoureux, Nicolas Flagey, F. Boulanger, A. Noriega-Crespo et autres

Interstellar medium studies rely on magnetohydrodynamic turbulence as a framework for interpretation. In this context, the statistical characterization of interstellar observations is of prime importance. We present a new perspective on diffuse interstellar matter by analyzing James Webb Space Telescope (JWST) observations …
