Study of Polarized Emission in Radio Halos and Filaments in the SKA Telescopes Era
Valentina Vacca, Federica Govoni, Matteo Murgia +12
Synchrotron diffuse emission in merging galaxy clusters and along filaments connecting them demonstrates the presence of relativistic particles and magnetic fields in these environ…
Probing the Fundamental Nature of Particle Dark Matter
Marco Regis, Aritra Basu, Geoff Beck +7
Understanding the fundamental nature of dark matter (DM) is one of the most significant scientific challenges of our time. A compelling hypothesis is that DM consists of a new, yet…
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…
Constraints on dark matter annihilation and turbulent reacceleration set by high-frequency observations of the radio halo in the Coma cluster
P. Marchegiani, V. Vacca, F. Govoni +2
We study the impact of the recent observation of the radio halo in the Coma galaxy cluster at 6.6 GHz with the Sardinia Radio Telescope on models based on turbulent reacceleration…
Observations of the galaxy cluster CL 0217+70 and its surrounding region at 1.4 GHz with the Sardinia Radio Telescope
P. Marchegiani, V. Vacca, F. Govoni +3
We present the results of observations performed with the Sardinia Radio Telescope (SRT) at 1.3-1.8 GHz of the galaxy cluster CL 0217+70 and a region aroun…
Filaments in and between galaxy clusters at low and mid-frequency with the SKA telescope
Valentina Vacca, Federica Govoni, Matteo Murgia +6
Understanding the magnetised Universe is a major challenge in modern astrophysics, and cosmic magnetism has been acknowledged as one of the science key drivers of the most ambitiou…
