There are approx. 40-50 clusters are hosting diffuse radio sources to the date. The goal of the work is to extend our current knowledge of the radio halo and relic populations to z >~ 0.3. In this talk, we will present archival radio (GMRT+EVLA) and X-ray (Chandra) data analysis of six MACS (MAssive Cluster Survey) clusters. These six clusters are massive and dynamically disturbed. We found that out of six clusters, two clusters host confirmed radio halos, two clusters host candidate radio halos, and remaining two are upper limit clusters. We also estimate the X-ray cluster morphological parameters (Gini, M20 and Concentration) for these MACS clusters. We confirm that diffuse intra-cluster radio sources are associated with major mergers. |
