Implementation of frequency-correlated noise in CMB component separation: Method, Validation, and Early Applications

L. Zapelli, M. Bersanelli, L. P. L. Colombo +24

Parametric component separation methods used in cosmic microwave background (CMB) analyses commonly assume instrumental noise to be uncorrelated between frequency channels. This ap…

Flux jump correction in the QUBIC TES data pipeline

Belen Costanza, Lucas Merlo Azzolina, Claudia G. Scoccola +20

Flux jumps occur in the readout electronics of Transition Edge Sensor (TES) detectors coupled to Superconducting Quantum Interference Devices (SQUIDs), as a consequence of the peri…

Spectral Imaging with QUBIC: building astrophysical components from Time-Ordered-Data using Bolometric Interferometry

M. Regnier, T. Laclavere, J-Ch. Hamilton +33

The detection of B-modes in the CMB polarization pattern is a major issue in modern cosmology and must therefore be handled with analytical methods that produce reliable results. W…

Spectral Imaging with QUBIC: building frequency maps from Time-Ordered-Data using Bolometric Interferometry

M. Regnier, T. Laclavère, J-Ch. Hamilton +34

The search for relics from the inflation era in the form of B-mode polarization of the CMB is a major challenge in cosmology. The main obstacle appears to come from the complexity…

Measuring the CMB primordial B-modes with Bolometric Interferometry

A. Mennella, P. Ade, A. Almela +111

The Q&U Bolometric Interferometer for Cosmology (QUBIC) is the first bolometric interferometer designed to measure the primordial B-mode polarization of the Cosmic Microwave Backgr…
