Robust paths to primordial modes in the presence of polarised point source contamination
Arianna Rizzieri, Giorgia Zagatti, David Alonso
A detection of primordial modes in the Cosmic Microwave Background (CMB) polarisation relies on a robust control and removal of contamination from astrophysical polarised foreg…
Validation of harmonic-space likelihood methods for LiteBIRD B-mode polarisation analysis
G. Galloni, P. Campeti, C. Gimeno-Amo +112
The LiteBIRD satellite mission aims to measure the tensor-to-scalar ratio with unprecedented sensitivity through observations of the cosmic microwave background (CMB) -mode…
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…
Contribution to the 2026 Cosmology session of the 60th Rencontres de Moriond: Galactic moments: Understanding polarized foregrounds complexity in the quest for CMB primordial modes with LiteBIRD
S. Vinzl, J. Aumont, L. Vacher +4
Accurate modeling of polarized Galactic emission has become a major challenge for current and next-generation cosmic microwave background (CMB) -mode experiments. Ignoring the s…
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 +108
Detection of primordial -mode polarization in the cosmic microwave background (CMB) from tensor perturbations generated during inflation is a major scientific goal of future CMB…
Setting requirements on out-of-band rejection for next-generation CMB experiments. Application to the LiteBIRD instrument
L. Mousset, L. Montier, J. Aumont +15
Next-generation cosmic microwave background experiments have very stringent constraints to achieve the required sensitivity to target polarization modes. In this work, we inten…
A GPU-Accelerated JAX Framework for Robust Parametric Component Separation and Clustering Optimization for CMB Polarization Satellites
Wassim Kabalan, Arianna Rizzieri, Wuhyun Sohn +6
We present a novel, JAX-powered implementation of a parametric component-separation method for CMB polarization data, explicitly designed to handle spatially varying foreground Spe…
