Abstract Type : Poster Abstract Category : Extragalactic Astronomy Abstract : We present the results obtained from a detailed analysis of a deep Chandra observation of the bright FR II radio galaxy 3C320 cluster at redshift z=0.342. A pair of X-ray cavities are detected along East and West directions from the centre of 3C320 at an average distance of ~40 kpc respectively. X-ray and radio images of the cluster reveal peculiar positioning of cavities. Radio lobes and X-ray cavities are apparently not spatially coincident and exhibit. Radial temperature and density profiles reveal the presence of a cool core in the cluster. Imaging and spectral studies showed the removal of substantial amount of matter from the core of the cluster by the radio jets. Detection of inflating cavities at an average distance of ~40 kpc from the centre implies that the central engine feeds a remarkable amount of radio power (~6.3 X 10^44 erg/s) into the intra-cluster medium over ~10^7 yr, the estimated age of cavity. The cooling luminosity of the cluster was estimated to be ~3.40 X 10^43 erg/s, which confirms that the AGN power is sufficient to quench the cooling. |
