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…

On the computational feasibility of Bayesian end-to-end analysis of LiteBIRD simulations within Cosmoglobe

R. Aurvik, M. Galloway, E. Gjerløw +107

We assess the computational feasibility of end-to-end Bayesian analysis of the JAXA-led LiteBIRD experiment by analysing simulated time ordered data (TOD) for a subset of detectors…

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…

First release of LiteBIRD simulations from an end-to-end pipeline

M. Bortolami, N. Raffuzzi, L. Pagano +107

The LiteBIRD satellite mission aims at detecting Cosmic Microwave Background modes with unprecedented precision, targeting a total error on the tensor-to-scalar ratio of $Î…

On beam characterization of ground-based CMB radio telescopes using UAV-mounted sources: application to the QUIJOTE TFGI and plans for LSPE-Strip

Fabio Paonessa, Lorenzo Ciorba, Giuseppe Addamo +22

The Large Scale Polarization Explorer (LSPE) project, funded by the Italian Space Agency (ASI), includes the development of LSPE-Strip, a ground-based radio telescope for observing…

The LSPE-Strip Pointing Reconstruction and Star Tracker

Michele Maris, Maurizio Tomasi, Matteo Baratto +18

This paper aims to describe the Pointing Reconstruction Model (PRM) and the prototype Star Tracker, which will be mounted on LSPE-Strip, a microwave Q- and W-band CMB telescope pla…
