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…
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…
Addressing Synchrotron Challenges for CMB Observations: ELFS-SA Collaboration for Robust Foreground Removal
E. de la Hoz, A. Mennella, K. Arnold +17
Upcoming cosmic microwave background (CMB) experiments aim to detect primordial gravitational waves with unprecedented sensitivity. Effective foreground removal is essential to avo…
QUIJOTE scientific results -- VIII. Diffuse polarized foregrounds from component separation with QUIJOTE-MFI
E. de la Hoz, R. B. Barreiro, P. Vielva +23
We derive linearly polarized astrophysical component maps in the Northern Sky from the QUIJOTE-MFI data at 11 and 13 GHz in combination with the WMAP K and Ka bands (23 and 33 GHz)…
Robustness of cosmic birefringence measurement against Galactic foreground emission and instrumental systematics
P. Diego-Palazuelos, E. Martínez-González, P. Vielva +11
The polarization of the cosmic microwave background (CMB) can be used to search for parity-violating processes like that predicted by a Chern-Simons coupling to a light pseudoscala…
Polarization angle requirements for CMB B-mode experiments. Application to the LiteBIRD satellite
P. Vielva, E. Martínez-González, F. J. Casas +68
A methodology to provide the polarization angle requirements for different sets of detectors, at a given frequency of a CMB polarization experiment, is presented. The uncertainties…
In-flight polarization angle calibration for LiteBIRD: blind challenge and cosmological implications
Nicoletta Krachmalnicoff, Tomotake Matsumura, Elena de la Hoz +67
We present a demonstration of the in-flight polarization angle calibration for the JAXA/ISAS second strategic large class mission, LiteBIRD, and estimate its impact on the measurem…
Determination of Polarization Angles in CMB Experiments and Application to CMB Component Separation Analyses
E. de la Hoz, P. Diego-Palazuelos, E. Martínez-González +3
The new generation of CMB polarization experiments will reach limits of sensitivity never achieved before to detect the primordial B-mode signal. However, all these efforts will be…
