| Description | We propose to obtain a short XMM observation of a cluster of galaxies that is scheduled to be imaged in great deal with the Hubble Space Telescope. The HST observations will allow galaxies over an unprecendentedly large magnitude range to be studied. XMM observations will permit us to make a detailed comparison of the distribution of cluster members of different types to the intracluster medium. This cluster has no previous X-ray observations so without these observations the HST data cannot be used to their full potential. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
