| Description |
Extensive radio surveys of galaxy clusters are key to solving the long standing puzzles regarding the origins of diffuse radio emission from the intra-cluster medium- the radio halos, relics and mini-halos. The Extended GMRT Radio Halo Survey (EGRHS) is a deep radio survey of bright galaxy clusters at 610 and 240 MHz with the GMRT designed to study the statistical properties of radio halos and relics in the galaxy clusters. We summarize the results from this survey which is nearing completion. In addition to this we have undertaken a follow up of Planck detected clusters with the GMRT and the Jansky Very Large Array. We present the discovery of a radio halo and radio relic in new Planck clusters.
