Abstract	We propose a 100 ksec XMM observation of the isolated elliptical galaxy NGC2325,a fairly typical galaxy in terms of its X-ray and optical luminosity. Studies ofisolated galaxies allow us to investigate the intrinsic properties of the hotgas halos in early-type galaxies without the complicating effects of a clusteror group environment, and we will study in detail the metallicity, entropy, andtemperature profiles in this galaxy as indications of the effectiveness ofenrichment and feedback processes. In addition, we will shed light on the debateover the dark matter density profiles of ellipticals by uniquely determining themass profile of the same isolated galaxy using both deep X-ray and opticaldynamical measurements.

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.
