Also in the cluster scales, observation of X-ray cavities seem to be a direct evidence of the interaction between the gas in the intra-cluster medium and the central black hole. Recently Chatterjee et al.(2015) tried to compare the extended X-ray emission of active and normal galaxies to search for black hole activity in the intergalactic medium using data from the Chandra telescope. Their results were limited by the uncertainty of the Chandra point-spread-function. As a follow-up to that work we have used optically selected (under-luminous in X-ray) active galactic nuclei (AGN) of redshift between 0.3 to 0.6 to search for signatures of black hole activity in the extended emission in high redshift galaxies.Also amongst these AGN the ones belonging to groups or clusters were removed to produce a source list of isolated AGN and galaxies in order to look for the effect of cluster dark matter halo on the extended emission of the individual galaxies. The results suggest that the AGN host galaxies have a lower extended emission compared to the normal galaxies in the vicinity of the central engine. |
