The AGN and radio activity from the supermassive blackholes at the centres of these galaxies are believed to play a major role in heating the intra-cluster medium. We investigate the optical spectra from the Sloan Digital Sky Survey of a large sample of BCGs in massive clusters. We classify the BCGs into star forming and AGN type based on their locations in the diagnostic diagrams. The connection between the spectral properties of the BCGs and the occurrence of radio sources in them will be presented. |
