Abstract:

Galaxy cluster mergers trigger Mpc-scale shocks in the ICM, which can accelerate particles to relativistic energies to form arc-shaped radio relics. Last year, we discovered a spectacular radio relic in the Planck cluster A3411. The relic has a complex, fragmentary morphology, at odds with the arc-shaped shocks predicted by hydrodynamical simulations. In light of this unexpected discovery, we propose for a 169-ks Suzaku observation to characterize the ICM properties at the radio relic in A3411. The combination of high-quality X-ray and radio data will provide a unique opportunity to (1) measure the shock properties and relate them to the radio structures; (2) explore the reason for the fragmentation of the relic; (3) model the merger event; and (4) test different shock acceleration models.
