Discovery of the correspondence between intra-cluster radio emission and
  a high pressure region detected through the Sunyaev-Zel'dovich effect
  We analyzed new 237 MHz and 614 MHz GMRT data of the most X-ray luminous
galaxy cluster, RX J1347-1145. Our radio results are compared with the MUSTANG
90 GHz 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 RX J1347-1145 is most likely related to a shock front propagating
into the intra-cluster medium.
