Abstract (from CDS):

We analyzed new 237MHz and 614MHz GMRT data of the most X-ray luminous galaxy cluster, RXJ1347-1145. Our radio results are compared with the MUSTANG 90GHz Sunyaev-Zel'dovich effect map and with re-processed Chandra and XMM-Newton archival data of this cluster. We point out for the first time in an unambiguous way the correspondence between a radio excess in a diffuse intra-cluster radio source and a hot region detected through both Sunyaev-Zel'dovich effect and X-ray observations. Our result indicates that electron re-acceleration in the excess emission of the radio mini-halo at the center of RXJ1347-1145 is most likely related to a shock front propagating into the intra-cluster medium.
