A746: A Smorgasbord of Particle Acceleration

Abell 746 is a unique system hosting a spectacular double radio relic, apossible radio halo, and two radio bright diffuse regions to the east of thecluster. With our proposed XMMNewton and JVLA observations, along withexisting low frequency radio data, we will (1) understand the origin of complexdiffuse radio sources; (2) probe the underlying particle acceleration mechanism;(3) characterize the properties of the shocks responsible for these sources; (4)determine the merger scenario by comparison with simulations; and (5) studypolarization properties of the relics and the magnetization of the intraclustermedium through Faraday analysis. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
