Scientific paper

Understanding the transport of energy and metals from central dominant galaxies in clusters into the intracluster medium (ICM) is vital to any model for the evolution of structure in the Universe. We propose to use a 50ks EPIC MOS+pn observation of the core (inner 12') of the Antlia Cluster to study the role of gas motions and turbulent diffusion in the chemical enrichment and heating of the ICM in a cluster with a sharply rising abundance profile, but without a cool core. We will map temperature, density and abundances throughout the Antlia cluster core, construct pressure and entropy maps to track gas motions and heat flows, and test models of metal enrichment due to turbulent motions powered by episodic outbursts from the central galaxy's AGN.
