Abstract | We propose a joint HST/XMM-Newton observing program to study both warm and hotgases in three optically-selected galaxy clusters at z=0.117-0.2108. Eachcluster has a UV-bright background QSO projected within the expected strongaccretion shock (< 2r_200). We will observe UV absorption lines of the O VIdoublet, HI Ly-alpha and Ly-beta, and other ion transitions in the rest frame ofthe clusters, using the HST/COS G130M grating. These absorption lines aresensitive to the thermal, kinetic, and chemical properties of warm (T < 10^6K) gas, associated with the halos of individual galaxies and the intraclustermedium. Chandra/ACIS observations will be used to measure the luminosity,temperature, and morphology of the hot gas component of the clusters. |

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. |
