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…
-sure. Part II. Scattering transforms as robustness test for tensor-to-scalar ratio detection from CMB observations
Claudio Ranucci, Sébastien Pierre, Léo Vacher +7
Galactic foregrounds represent a major contamination to the measurement of primordial -modes from observations of the Cosmic Microwave Background polarisation. Even after the ap…
Combining Systematic Effects in CMB Polarization Experiments through map-based simulations: application to LiteBIRD's HWP non-idealities and detectors non-linearity
Silvia Micheli, Francesco Piacentini, Tommaso Ghigna +10
We quantify the impact of coupled instrumental systematics on next-generation CMB polarization experiments targeting primordial -mode polarization, with a focus on the forthcomi…
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…
Status and future development of the COSMOCal Project for absolute CMB polarization calibration
Silvia Micheli, Alessia Ritacco, Alessandro Carones +36
Cosmic Microwave Background (CMB) polarization measurements are pushing instrumental sensitivities to levels where calibration systematics become a dominant limitation. The large d…
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
We present a cross-calibration algorithm that determines the relative calibration of detectors within the same frequency band of a CMB experiment. The method iteratively compares s…
BROOM: a python package for model-independent analysis of microwave astronomical data
Alessandro Carones, Sijil Jose, Aliza Mustafa +2
We present BROOM, a new python package for the application of blind, minimum-variance component-separation techniques to microwave observations. The package enables the reconstruct…
Blind mitigation of foreground-induced biases on primordial modes for ground-based CMB experiments
Aliza Mustafa, Alessandro Carones, Nicoletta Krachmalnicoff +2
Observations of the Cosmic Microwave Background (CMB) B-mode polarisation provide a unique probe of inflationary physics. Extracting a reliable constraint on the tensor-to-scalar r…
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…
