Nearby galaxy clusters present a unique opportunity to study the spatialvariation of the physical properties of the ICM and they also provide templatesto test the biases introduced by simplifications used in the analysis of moredistant clusters. Centaurus stands out as the optimal choice for such analysisin its category, due to its brightness &/ proximity. We propose 4 shortpointings that, together with the central archived ones, will allow us to map SNType enrichment, gas bulk velocities, and other ICM physical parameters up tovirgul0.35 of its virial radius. This analysis will address several current issues,such as the excess SN Ia pollution in the outer cluster regions and the currentinteraction with the incoming group Cen 45.

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.
