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…
Untangling dust emission and cosmic infrared background anisotropies with the scattering transform statistics
Srijita Sinha, Tuhin Ghosh, Erwan Allys +2
The template-fit approach is often used to separate Galactic dust emission from cosmic infrared background (CIB) anisotropies in low column density regions, under the a…
The multiphase interstellar medium as a common origin for magnetic misalignment and TB parity violation
Andrea Bracco, Ari J. Cukierman, Raphael Skalidis +1
We present an original data analysis and a physical model that provide new insights into the origin of, and relationship between, two observables of the dusty, polarized Galaxy at…
Separation of polarized dust emission in Planck observations with Scattering Transforms
Alexandros Tsouros, Elisa Russier, Erwan Allys +3
Polarized dust emission is a major astrophysical foreground contaminant of the cosmic microwave background polarization (CMB), which must be accurately measured to look for the fai…
Variance of dust temperature and spectral index in Planck polarization data using spin-moment expansion
Vincent Guillet, Léo Vacher, Jonathan Aumont +4
Thermal dust is the major polarized foreground hindering the detection of primordial cosmic microwave background (CMB) B-modes. Its signal exhibits complex behavior in frequency sp…
