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…
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…
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…
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…
A chemically etched D-band waveguide orthomode transducer for CMB measurements
E. Manzan, A. Mennella, F. Cavaliere +21
This study presents a prototype D-band waveguide orthomode transducer (OMT) fabricated using chemically etched brass platelets. This method offers a fast, cost-effective, and scala…
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…
