We propose to observe 10 galaxies from a unique sample of nearby,isolated ellipticals for which we have extensive optical and near-IRdata. We have three broad goals: (1) to determine the relationship, ifany, between the X-ray halo mass and optical galaxy mass, (2) tocompare the general properties of isolated ellipticals with those ofellipticals in denser environments, and (3) to search for directevidence that ellipticals can evolve from the merger of poor groups.The sensitivity and spatial resolution of XMM makes it possible toexamine the relationship between the X-ray and optical properties with

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.
