|Title||INVESTIGATING THE ELEMENTAL ABUNDANCE PARADOX IN ELLIPTICAL GALAXIES WITH XMM|

|Description||Essential clues to the structure and history of elliptical galaxies lie embedded in their hot X-ray emitting halos. XMM-Newton observations, in conjunction with optical data and detailed theoretical modeling, offer the unique opportunity to obtain sufficient counts on all r^ant length-scales to study the relationship between dark and luminous matter, and constrain the earliest star formation in ellipticals. We therefore propose to observe two elliptical galaxies, NGC 4374 and NGC 5813, with extended thermal X-ray emission and excellent optical spectroscopy.|

|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.
