| Description | The mass profiles of elliptical galaxies are important probes of galaxy formation and cosmology. Only a few elliptical galaxies have detailed mass measurements from X-rays because of the lack of suitable targets in terms of total mass (< virgul10^{13} m_sun) and relaxed dynamical states appropriate for hydrostatic analysis. We have identified a sample of 10 (hot) gas-rich isolated elliptical galaxies well-suited for X-ray studies of mass profiles on the galaxy scale. We request deep XMM observations to map the detailed profiles of stars, dark matter, and hot gas for the 5 systems in the sample lacking high-quality XMM data. This sample will serve as a benchmark laboratory for hydrostatic studies of the hot gas in isolated 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. |
