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…
Signals from the early Universe: a comprehensive search for primordial features in Planck CMB datasets
Antonio Raffaelli, Mario Ballardini, Nicola Barbieri
We investigate the presence of primordial oscillatory features in measurements of CMB anisotropies through a systematic comparison of phenomenological templates. Building upon prev…
Knot reconstruction of the scalar primordial power spectrum with Planck, ACT, and SPT CMB data
Antonio Raffaelli, Mario Ballardini
We investigate a non-parametric Bayesian method for reconstructing the primordial power spectrum (PPS) of scalar perturbations using temperature and polarisation data from the {\em…
Refining the nonlinear modelling of primordial oscillatory features
Mario Ballardini, Nicola Barbieri
Primordial oscillatory features in the power spectrum of curvature perturbations are sensitive probes of the dynamics of the early Universe and can provide insights beyond the stan…
