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…
PROTOCALC, A W-band polarized calibrator for CMB Telescopes: application to Simons Observatory and CLASS
Gabriele Coppi, Nadia Dachlythra, Federico Nati +11
Current- and next-generation Cosmic Microwave Background (CMB) experiments will measure polarization anisotropies with unprecedented sensitivities. The need for high precision in t…
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…
Simons Observatory: Characterization of the Large Aperture Telescope Receiver
Tanay Bhandarkar, Saianeesh K. Haridas, Jeff Iuliano +41
The Simons Observatory (SO) is a ground-based cosmic microwave background (CMB) survey experiment that currently consists of three 0.42m small-aperture telescopes (SATs) and one 6m…
