Proof of concept of the COSMOCal project at the IRAM 30m telescope
S. Savorgnano, L. Bizzarri, A. Ritacco +25
This work reports on a test campaign conducted at the IRAM 30m telescope to validate the COSMOCal instrument, a novel concept for absolute calibration of polarization angle, beam p…
Status and future development of the COSMOCal Project for absolute CMB polarization calibration
Silvia Micheli, Alessia Ritacco, Alessandro Carones +36
The paper outlines the COSMOCal project, which will place an artificial polarized microwave source on a geostationary satellite to provide stable absolute calibration for CMB polar…
High-accuracy polarimetry for CMB: new frontiers with the POLOCALC project
A. Novelli, F. Astori, L. Bizzarri +8
Modern telescopes observing the Cosmic Microwave Background (CMB) polarization require an exquisite control of systematics to target Inflationary Gravitational Waves (IGW), Cosmic…
Status of the COSmological Microwave Observations CALibrator
L. Mousset, J. Aumont, S. Berta +33
As the sensitivity of CMB telescopes increases, the need for precise calibration becomes critical. Started in 2022, the COSMOCal project aims to place an artificial polarized sourc…
The Simons Observatory: Quantifying the impact of beam chromaticity on large-scale B-mode science
Nadia Dachlythra, Kevin Wolz, Susanna Azzoni +17
The Simons Observatory (SO) Small Aperture Telescopes (SATs) will observe the Cosmic Microwave Background (CMB) temperature and polarization at six frequency bands. Within these ba…
The Simons Observatory: Detector Polarization Angle Calibration using Sparse Wire Grid with Initial Data Sets of the Small Aperture Telescope
Hironobu Nakata, Shunsuke Adachi, Kyohei Yamada +22
Improved measurements of -modes in the cosmic microwave background can be obtained through accurate calibration of the orientation of detector antennas as projected onto the sky…
