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…
A First Post-Friedmann Extension of the Schrödinger Approach to Cosmic Structure Formation
Yiwen Deng-Huang, Daniele Bertacca, Sabino Matarrese
We extend the Schrödinger approach to large-scale structure formation beyond the Newtonian regime by working at first post-Friedmann (1PF) order. The standard Schrödinger--Poisso…
Exploring Gravitational Wave Signatures Due to Primordial Non-gaussianity and Large Scale Structure Using SKAO
H. V. Ragavendra, Giulia Capurri, Alina Mierna +8
This chapter explores theoretical and observational strategies to use the stochastic gravitational-wave background detectable by Square Kilometre Array Observatory (SKAO) as a prob…
A cross-calibration approach for polarisation-sensitive detectors in CMB experiments: application to LiteBIRD's polarisation angle calibration
A. Novelli, F. Piacentini, S. Micheli +102
One of the current challenges in observational cosmology is obtaining high-precision polarisation maps of the CMB to measure primordial -modes and constrain the tensor-to-scalar…
Non-Gaussianity of Tensor Induced Density Perturbations
Mariam Abdelaziz, Pritha Bari, Sabino Matarrese +1
We investigate the non-Gaussianity of second-order matter density perturbations induced by primordial gravitational waves (GWs). These tensor-induced scalar modes arise from local…
