| Abstract | We propose a deep 140ks observation of the Centaurus cluster, one of thebrightest clusters. It presents an ideal opportunity to study the physics ofenrichment in great detail, given its very high metallicity, its proximity, itscool temperature, and luminosity. Our Chandra results show that there is thesame ratio of Type Ia to II SN abundances over the inner 60kpc, which is ofgreat importance to understanding cluster enrichment. We will investigate indetail whether this is replicated in the outer regions, and relate this toenrichment mechanisms. The observation is very well matched to XMM. We willstudy the merger between the two subgroups. The cluster also shows a very widerange in temperature, making it ideal to limit the amount cooling out of the X-ray band. |

| 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. |
