| Abstract | We propose deep XMM-Newton observations of young, post-merger ellipticalgalaxies to determine Si to Fe abundance ratios in the hot ISM and to comparewith those of typical old elliptical galaxies. Accurate measurement of Fe toalpha element abundance ratios is critical to understand the metal enrichmenthistory from SNe Type Ia and II ejecta. Because the LX/LB ratios are low amongthe proposed ellipticals, measurements of individual element abundances areuncertain and often controversial. However, the Si to Fe abundance ratio can betightly constrained by analyzing the proposed XMM-Newton data, in conjunctionwith available Chandra data to constrain the LMXB contribution to the XMMspectra. These results can constrain different evolutionary scenarios. |

| 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. |
