|Title||Snapshots of Isolated Elliptical Galaxies|
|Author||Prof David Buote|
|Description||The properties of dark matter halos on galactic scales remain a largely untapped resource for cosmological studies. X-ray observations offer potentially the most promising means to study dark matter in isolated elliptical galaxies, but there is presently a lack of known suitable candidates for study. Therefore, we propose a snapshot survey of 9 systems to identify isolated elliptical galaxies with X-ray properties similar to the best examples currently known. Deep follow-up exposures with XMM and Chandra of promising targets will then be sought for detailed analysis of their dark matter distributions.|

|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.
