Abstract / Description:Wide-angle tail (WAT) galaxies are radio galaxies whose jets are bent forming a wide C shape. The bending of the jets is a result of ram pressure, due to the relative motion of the host galaxy and the intra-cluster medium. We present an analysis of a WAT galaxy located in a galaxy group in the COSMOS field at the redshift of z = 0.53 (CWAT-02). An in-depth study of CWAT-02 and its surroundings reveals many indications that this system in the process of an ongoing group merger. We analyze the radio jets of CWAT-02 and present an estimate of discrepancy between the observed and the intrinsic luminosity, due to Doppler beaming of the relativistic jets. We finally discuss the impact of radio-AGN heating from CWAT-02 into its environment.
