We propose a 180 ks XMM-Newton observation of the Antlia Cluster, the thirdclosest galaxy cluster in the sky. We will determine the central temperature, Siand Fe abundance structure of the cluster to constrain detailed chemicalenrichment processes in the nearest cluster without a strong cool core. Thedetailed abundance structure of the cluster will be resolved at the bestphysical resolution of any non-cool core cluster to date.

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.
