We propose to obtain a short XMM observation of a cluster of galaxies thatis scheduled to be imaged in great deal with the Hubble Space Telescope.The HST observations will allow galaxies over an unprecendentedly largemagnitude range to be studied. XMM observations will permit us to makea detailed comparison of the distribution of cluster members of differenttypes to the intracluster medium. This cluster has no previous X-rayobservations so without these observations the HST data cannot be usedto their full potential.

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.
