| Description | We propose to observe the two groups of galaxies NGC 5044 and NGC 5813 each with 130 ks exposure time. We will combine these data with archival data of three other groups. The RGS spectra will reveal accurate abundances of nitrogen and carbon, key elements produced both by massive stars and intermediate mass AGB stars. The EPIC spectra will give accurate abundances of all elements heavier than oxygen. The combined spectra allow us to measure the contributions to the metal enrichment by each of the individual categories: intermediate and low mass stars, core collapse supernovae and type Ia supernovae. In addition, we will measure the spatial distribution of these elements. |

| 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. |
