Description
I will summarise status and ongoing developments of a project investigating galaxy population properties in massive clusters at z~1.5 and progenitors about 1-1.5 Gyr earlier, in the context of the transition from the proto-cluster to established cluster regimes. In particular, I will present deep MeerKAT observations for both the Spiderweb protocluster and a complete sample of massive (a few times 10 to 14 Solar masses) clusters at z~1.5 that are ICM selected from the SPT-SZ survey. The radio continuum data are unique tools to probe dust-unbiased star formation and nuclear activity in these high-redshift environments, across the cluster virial volume and into the infall region, and in the wide-field structures around protocluster cores. Finally, I will show how this data can also be used, in a novel way, to study the impact of the cluster environments on their galaxy populations.
