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
Cosmic Microwave Background (CMB) polarization measurements are pushing instrumental sensitivities to levels where calibration systematics become a dominant limitation. The large d…
Correlation between active regions' spectra at high radio frequencies and solar flare occurrences
Sara Mulas, Alberto Pellizzoni, Marco Marongiu +31
High radio frequencies observations with the Italian network of large single-dish radio telescopes resulted in ~450 solar images between 2018 and 2023 in K-band frequency range (18…
Absolute reference for microwave polarization experiments -- The COSMOCal project and its proof of concept
A. Ritacco, L. Bizzarri, S. Savorgnano +25
The cosmic microwave background (CMB), a remnant of the Big Bang, provides unparalleled insights into the primordial universe, its energy content, and the origin of cosmic structur…
Study of solar brightness profiles in the 18-26 GHz frequency range with INAF radio telescopes II. Evidence for coronal emission
M. Marongiu, A. Pellizzoni, S. Righini +43
One of the most important objectives of solar physics is the physical understanding of the solar atmosphere, the structure of which is also described in terms of the density (N) an…
Study of solar brightness profiles in the 18-26 GHz frequency range with INAF radio telescopes I: solar radius
M. Marongiu, A. Pellizzoni, S. Mulas +32
The Sun is an extraordinary workbench, from which several fundamental astronomical parameters can be measured with high precision. Among these parameters, the solar radius $R_{\odo…
Solar observations with single-dish INAF radio telescopes: continuum imaging in the 18-26 GHz range
A. Pellizzoni, S. Righini, M. N. Iacolina +28
We present a new solar radio imaging system implemented through the upgrade of the large single-dish telescopes of the Italian National Institute for Astrophysics (INAF), not origi…
