Spectral Imaging with QUBIC: building astrophysical components from Time-Ordered-Data using Bolometric Interferometry
M. Regnier, T. Laclavère, et al.
This paper presents a method for separating astrophysical components directly from time-ordered data using QUBIC’s bolometric interferometry, improving map-making accuracy for CMB polarization analysis and reducing biases in cosmological parameter estimation. The approach leverages parallelized operators to handle foregrounds and systematic effects, enabling precise end-to-end simulations and analysis.
Spectral Imaging with QUBIC: building frequency maps from Time-Ordered-Data using Bolometric Interferometry
M. Regnier, T. Laclavère, et al.
This paper presents spectral-imaging with QUBIC, a method to reconstruct sub-frequency CMB polarization maps from time-ordered data, enabling improved foreground mitigation and unbiased estimation of primordial fluctuations through bolometric interferometry.
Bolometric interferometry and spectral: a QUBIC overview
Tom Laclavère
The Q \& U Bolometric Interferometer for Cosmology (QUBIC) is a new kind of cosmological instrument that uses interferometry to observe the sky. The unique synthesized beam of QUBIC has an important frequency dépendance that we use to increase spectral resolution and perform new component separation methods, allowing us to mitigate foreground contamination in an improved manner.

Spectral Imaging with QUBIC: Component separation methods using Bolometric Interferometry
This presentation introduces QUBIC, a bolometric interferometer designed to detect CMB B-modes by combining high-sensitivity bolometers with interferometric control of systematics. It introduces two spectral-imaging–based component separation methods, Frequency Map-Making (FMM) and Component Map-Making (CMM), which exploit the instrument’s intrinsic spectral resolution to enhance foreground mitigation and improve cosmological constraints.
