Radio observations of Planck clusters
Abstract Recently, a number of new galaxy clusters have been detected by the ESA‐ Planck satellite, the South Pole Telescope, and the Atacama Cosmology Telescope using the Sunyaev‐Zel'dovich effect. Several of the newly detected clusters are massive, merging systems with disturbed morphology in...
