We report the discovery of a radio relic in the Planck satellite discovered cluster PLCKG200.9-28.2 at a redshift of 0.22 using the Giant Metrewave Radio Telescope and the Karl G. Jansky VLA. It has a largest linear extent of a Mpc and is at a distance of 0.9 Mpc from the cluster centre. The analysis of archival XMM Newton data shows that it is a merging cluster based on the disturbed X-ray morphology and a high temperature of about 5 - 6 keV. We discuss the properties of this new relic and the host cluster and compare it with those of the other clusters with radio relics. |
