| Description | We propose to observe two galaxies from a sample of nearby, isolated ellipticals for which we have extensive optical and near-IR data. Our proposed targets are unique in that unlike other ellipticals, they are not surrounded by a population of dwarf galaxies. We will combine the proposed XMM-Newton observations with our existing data to: (1) determine the relationship, if any, between the X-ray halo mass and optical galaxy mass, (2) compare the properties of isolated ellipticals with those of ellipticals in denser environments, and (3) search for direct evidence that ellipticals can evolve from the merger of poor groups. These observations will help constrain models for the formation of elliptical galaxies. |

| 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. |
