Resumo:
A fraction of galaxy clusters host Mpc-scale Radio
Halos (RH), generated by ultrarelativistic electrons in the
magnetized intra cluster medium (ICM). In the current
view they trace turbulent regions in merging clusters, where relativistic particles are trapped and accelerated. This model has clear expectations about the statistical properties of RHs. To test these expectations large mass-selected samples of galaxy clusters with adequate radio and X-ray data are necessary. We used the Planck SZ cluster catalogue as suitable starting point of our investigation, selecting clusters with M500>6x10^14 Msun at 0.08
