Status and future development of the COSMOCal Project for absolute CMB polarization calibration

Silvia Micheli, Alessia Ritacco, Alessandro Carones +36

Cosmic Microwave Background (CMB) polarization measurements are pushing instrumental sensitivities to levels where calibration systematics become a dominant limitation. The large d…

Full-Stokes polarimetry with circularly polarized feeds - Sources with stable linear and circular polarization in the GHz regime

I. Myserlis, E. Angelakis, A. Kraus +8

We present a pipeline that allows recovering reliable information for all four Stokes parameters with high accuracy. Its novelty relies on the treatment of the instrumental effects…
