[en] We examine deep Chandra observations of the nearby Perseus and Centaurus galaxy clusters to examine AGN feedback and enrichment of the intracluster medium. We show evidence of 100 Myr of activity by the central nucleus in Perseus, generating shocks, bubbles and sound waves, heating the cluster core. Despite the AGN activity there exist 10⁹ solar masses of ∼5x10⁶ K gas embedded in an intracluster medium 5 to 10 times hotter than it. Transport properties of the intracluster medium are likely to be important. We observe and map the distribution of metals in the Centaurus cluster, and show that Type II supernova enrichment is important in even the core of this cluster. It has been relatively undisturbed for 8 Gyr with a close heating/cooling balance. (author)
