Galaxy clusters in different dynamical state: a multiband view from MeerKAT and uGMRT

Galaxy clusters are the largest gravitationally bound systems in the Universe, they are special laboratories where is it possible to investigate the evolution and the properties of galaxies in different environments, starting from their centre, going out to the virial radius and beyond. The properties of radio galaxies can be related to their environment and its dynamical status: nowdays, understand whether the observed properties of radio galaxies arise at formation (nature scenario), or they are an end-product of physical processes (nurture scenario) coming into play after galaxies have become part of a `group' or a `cluster' is difficult and much debated. We started this work, analyzing a sample of eleven Brightes Cluster Galaxies (BCGs) from ten galaxy clusters in the redshift range 0.2 < z < 0.4. They were selected because of the overlap between the Extended GMRT Radio Halo Survey (EGRHS) and the Cluster Lensing and Supernovae Survey with Hubble (CLASH). The main aim is to examine the radio properties of these galaxies considered `special' because of their position at the very centre of galaxy cluster potential well. In particular, to understand whether the main mechanism responsible for the radio emission, when detected, is mainly due to AGN activity or to Star Formation activity and which is the interplay between the two mechanisms, since both are of fundamental importance for the feedback phenomena.
