Constraints on the magnetic field in the hadronic scenario for the origin of the radio halo in the A1795 galaxy cluster
P. Marchegiani, V. Vacca, F. Loi +2
The radio halo in the cool-core galaxy cluster, A1795, has recently been proposed to be of hadronic origin, because it extends on megaparsec scales, where no turbulence is expected…

High significance detection at 4.8 GHz of the radio halo in the Coma galaxy cluster with the Sardinia Radio Telescope
P. Marchegiani, M. Murgia, F. Loi +4
We present the results of observations of the radio halo in the Coma galaxy cluster at 4.8 GHz performed with the Sardinia Radio Telescope. The radio halo in this cluster is detect…

First Sardinia Radio Telescope detection of the Sunyaev-Zel'dovich effect at 18.6 GHz
S. Cocchi, F. Loi, M. Murgia +5
Galaxy clusters imprint a distinctive signature on the cosmic microwave background through the thermal Sunyaev-Zel'dovich (SZ) effect, which enables to study the intracluster plasm…
