| Description | We propose to make the first comparison of intracluster light in the X-ray and optical bands for four clusters of galaxies. We have developed a new approach that constrains the stellar light profile out to at least 0.5 Mpc. The sensitivity, wide field, and spectral capabilities of XMM-Newton will allow us to derive the total mass and gas mass profiles out to a similar radius and to answer 1] whether the observed variations in the stellar light profiles of similar clusters reflect differences in the mass profiles or in the evolution of the stellar intracluster medium? and 2] what are the relative contributions of gas and stars to the overall baryon fraction? |

| 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. |
