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…
DEFROST: Detecting Excess in Faraday Rotation thrOugh Sophisticated analysis Techniques
Valentina Vacca, Sebastian Hutschenreuter, Andrea Cabriolu +7
Understanding origin and evolution of cosmological magnetic fields requires knowledge of magnetic fields in different extragalactic environments. In this context, a powerful tool i…
Estimating Flux Densities of Diffuse Cosmological Radio Sources Exploiting Vision Transformers
Nicoletta Sanvitale, Claudio Gheller, Franco Vazza +3
We present TUNA, a Vision-Transformer based network adapted from segmentation to flux regression for faint, diffuse radio emission. Trained on LOFAR-like mock observations derived…
The First High Frequency Technosignature Search Survey with the Sardinia Radio Telescope
Lorenzo Manunza, Alice Vendrame, Luca Pizzuto +30
The quest for radio signals from technologically-advanced extraterrestrial intelligence has traditionally concentrated on the vicinity of 1.4 GHz. In this paper, we extend the sear…
Mapping Diffuse Radio Sources Using TUNA: A Transformer-Based Deep Learning Approach
Nicoletta Sanvitale, Claudio Gheller, Franco Vazza +6
Vision Transformers are used via a customized TransUNet architecture, which is a hybrid model combining Transformers into a U-Net backbone, to achieve precise, automated, and fast…
The MeerKAT Fornax Survey IV. A close look at the cluster physics through the densest rotation measure grid
Francesca Loi, Paolo Serra, Matteo Murgia +5
Using the Square Kilometre Array (SKA) mid precursor MeerKAT, we acquired broadband spectro-polarimetric data in the context of the MeerKAT Fornax Survey to study the Fornax cluste…
