Abstract	The mass profiles of elliptical galaxies are important probes of galaxyformation and cosmology. Only a few elliptical galaxies have detailed massmeasurements from X-rays because of the lack of suitable targets in terms oftotal mass (< ~10^{13} m_sun) and relaxed dynamical states appropriate forhydrostatic analysis. We have identified a sample of 10 (hot) gas-rich isolatedelliptical galaxies well-suited for X-ray studies of mass profiles on the galaxyscale. 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-qualityXMM data. This sample will serve as a benchmark laboratory for hydrostaticstudies of the hot gas in isolated elliptical galaxies.

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.
