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…
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…
Robust CMB polarisation mapmaking with a rotating half-wave plate
Wuhyun Sohn, Simon Biquard, Josquin Errard +1
We present a novel mapmaking method for obtaining unbiased estimates of CMB polarisation, tailored to modern CMB experiments with a rotating half-wave plate. These experiments are…
Furax: A Modular JAX Framework for Linear Operators in Astrophysical and Cosmological Data Analysis
Pierre Chanial, Simon Biquard, Wassim Kabalan +10
The Framework for Unified and Robust data Analysis with JAX (Furax) is an open-source Python framework for modeling data acquisition systems and solving inverse problems in astroph…
Recovering unbiased CMB polarization maps using modern ground-based experiments with minimal assumptions about atmospheric emission
Simon Biquard, Josquin Errard, Radek Stompor
We present a study of unbiased reconstruction of cosmic microwave background (CMB) polarization maps from data collected by modern ground-based observatories. Atmospheric emission…
PROTOCALC, A W-band polarized calibrator for CMB Telescopes: application to Simons Observatory and CLASS
Gabriele Coppi, Nadia Dachlythra, Federico Nati +11
Current- and next-generation Cosmic Microwave Background (CMB) experiments will measure polarization anisotropies with unprecedented sensitivities. The need for high precision in t…
