|Title||The Mass and Abundance Profiles of Clusters Out to the Virial Radius|
|Author||Dr Richard Mushotzky|
|Description||GT- We propose to observe three luminous clusters at redshift approximately one-tenth with XMM in order to measure temperature and abundance profiles out to the virial radius -- the largest radius at which the cluster is expected to be in dynamical equilibrium. The temperature profile will be of sufficient extent and precision to constrain the shape of the dark matter spatial distribution, as well as the total mass. The total and relative abundance profiles are a powerful probe of the star formation and mass loss history of cluster galaxies. .|

|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.
