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…

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…

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

N. Raffuzzi, A. Carones, M. Monelli +101

Although half-wave plates (HWPs) are becoming a popular choice of polarization modulators for cosmic microwave background (CMB) experiments, their non-idealities can introduce syst…

On the computational feasibility of Bayesian end-to-end analysis of LiteBIRD simulations within Cosmoglobe

R. Aurvik, M. Galloway, E. Gjerløw +107

We assess the computational feasibility of end-to-end Bayesian analysis of the JAXA-led LiteBIRD experiment by analysing simulated time ordered data (TOD) for a subset of detectors…

First release of LiteBIRD simulations from an end-to-end pipeline

M. Bortolami, N. Raffuzzi, L. Pagano +107

The LiteBIRD satellite mission aims at detecting Cosmic Microwave Background modes with unprecedented precision, targeting a total error on the tensor-to-scalar ratio of $Î…

Requirements on bandpass resolution and measurement precision for LiteBIRD

S. Giardiello, A. Carones, T. Ghigna +95

In this work, we study the impact of an imperfect knowledge of the instrument bandpasses on the estimate of the tensor-to-scalar ratio in the context of the next-generation Lit…
