Correlations of the feedback energy and BCG radio luminosity in galaxy clusters

12 Jul 2018 Iqbal Asif Kale Ruta Nath Biman B. Majumdar Subhabrata

We study the excess entropy and the corresponding non-gravitational feedback energy ($E_{feedback}$) in the intra-cluster medium (ICM) by considering a sample of 38 galaxy clusters using Chandra X-ray and NRAO VLA Sky Survey (NVSS)/Giant Metrewave Radio Telescope (GMRT) radio observations. We find moderate correlation of the feedback energy and brightest cluster galaxy (BCG) radio luminosity ($L_R$) with the various cluster thermal properties... (read more)
