|Title||X-RAY PROPERTIES OF ISOLATED EARLY-TYPE GALAXIES|
|Author||Dr BIRGIT KELM|
|Description||We plan to derive the X-ray properties of 3 isolated early type galaxies to provide answers to fundamental issues concerning the connection between environment and E galaxies formation. The X-ray data will tell us whether group dominant Es are indeed overluminous and significantly more extended relative to isolated ones. While the presence of extended halos provides strong observational support to theories assuming that bright Es are formed within groups, non detections might severely challenge these hierarchical formation models. Isolated E samples used in previous works include non isolated Es, due to limitations in the parent sample from which they are drawn. We therefore have selected a new sample with solid isolation criteria.|

|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.
