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

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
