| Description | We propose to complete the mosaic of XMM observations in the nearby bright galaxy group NGC 5044. The two previous offset observations in the South and in the West showed a very low iron abundance, 4 times less than that predicted by standard SNcc and SNIa enrichment models for rich clusters. The new XMM observations in the North and East will complete the mosaic and may point to an higher then expected uplifting of enriched gas by sloshing, advancing our understanding of metal enrichment in groups. If instead the low abundance will be confirmed it will be a challenge to current enrichment scenarios. |

| 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. |
