Constraining the X-ray Features of the Double Radio Relic Cluster ZWCL1856+6616 with High-Resolution Chandra Observation
Abstract
The supersonic collision of two galaxy subclusters induces shocks into the intracluster medium. Radio relics are synchrotron emission from charged particles that are accelerated in the shocks. The shocks in galaxy clusters are weak ($M<3$) and have low particle acceleration efficiency, which is insufficient to produce the observed radio relics. To understand the shock - radio relic connection, a clear understanding of the cluster merger scenario is required. ZwCl 1856.8+6616 is a low-mass merging cluster that is rich with features such as double radio relics, slingshot tails, and a possible X-ray cavity. We propose an additional 223 ks Chandra observation to detect the X-ray shocks, confirm and investigate the slingshot tails, and probe the X-ray cavity.
