The giant radio source 0917+75: Origin and properties
G. Giovannini, N. Biava, M. Girardi +11
Context. Several author have studied the giant radio source GRS0917 + 75 , but its origin remains unclear. Aims. This source is unusual, because of its large size and its location…
The SKA View of Cool-core Clusters: Evolution of Radio Mini-halos and AGN Feedback
Myriam Gitti, Paolo Tozzi, Francesco Ubertosi +12
In about 70 per cent of relaxed, cool-core galaxy clusters, the brightest cluster galaxy (BCG) is radio loud, showing non-thermal radio jets and lobes ejected by the central active…
Application of Bayesian Statistical Tools to SKA Telescopes Polarization Surveys to Study Magnetization of the Large-scale Structure of the Universe
Valentina Vacca, Sebastian Hutschenreuter, Andrea Cabriolu +18
Understanding cosmological magnetic fields requires a detailed knowledge of magnetism in the different environments of the large-scale structure of the Universe. Magnetic fields ar…
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…
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…
