| Description | Abell 2199 and Abell 3571 show indications of central abundance enhancements due to SN Ia ejecta contamination. The mechanisms that create the enhancement are not clear. Some suggested mechanisms to explain this excess of SN Ia material in the central regions are: ram-pressure stripping, SN Ia suppressed winds and normal stellar mass loss. The discrimination between metal injection mechanisms can be done by determining the distribution of elemental abundance ratios in clusters. We propose to observe A2199 and A3571 for 20 ksec and 30 ksec respectively (EPIC MOS) to determine the distribution of individual abundances and abundance ratios. The results will be used in the discrimination of metal enrichment mechanisms, which will provide fundamental constraints on the energetics of the ICM. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
