A minimal power-spectrum-based moment expansion for CMB B-mode searches
S. Azzoni, M. H. Abitbol, D. Alonso +3
The characterization and modeling of polarized foregrounds has become a critical issue in the quest for primordial -modes. A typical method to proceed is to factorize and parame…

The Simons Observatory: gain, bandpass and polarization-angle calibration requirements for B-mode searches
Maximilian H. Abitbol, David Alonso, Sara M. Simon +45
We quantify the calibration requirements for systematic uncertainties for next-generation ground-based observatories targeting the large-angle -mode polarization of the Cosmic M…

QUBIC: using NbSi TESs with a bolometric interferometer to characterize the polarisation of the CMB
M. Piat, B. Bélier, L. Bergé +135
QUBIC (Q \& U Bolometric Interferometer for Cosmology) is an international ground-based experiment dedicated in the measurement of the polarized fluctuations of the Cosmic Microwav…
