The Narrow Angle Tail (NAT) radio sources are featured by tails bent in a narrow `V' like shape. The jet bending in case of Wide Angle Tail (WAT) radio galaxies are such that, the WATs exhibit wide `C' like morphologies. The relative motion of the host galaxies through the inter-cluster medium or the strong inter-cluster wind is believed to cause the bending of the radio jets. Tailed radio galaxies are generally found in a rich cluster of galaxies. It is seen that NAT galaxies reside towards the edge whether WAT galaxies are located towards the center of a cluster. One can use NAT and WAT sources as a probe to detect nearby galaxy cluster. We have used our set of newly discovered head-tailed radio galaxies (Sasmal et al., 2018) to look for the hitherto undiscovered cluster of galaxies. Here we are presenting the discovery of three new clusters of galaxies from our study. |
