We propose a pilot joint XMM-Newton/HST observing program to study both warm and hot gases in two optically-selected galaxy clusters at z=0.1-0.2. Eachcluster has a UV-bright background QSO projected within the expected strong accretion shock. We will measure the luminosity, temperature,and morphology of the hot gas component and observe UV absorption lines of the O VI doublet and other ion transitions of the clusters. These lines are sensitive to the thermal, kinetic, and chemical properties of warm gas, associated with the halos of individual galaxies and the intracluster medium.

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.
