Dark matter is the dominant contribution to the matter density in the Universe,but the baryonic component, seen in galaxies and in hot gas, is the most readilystudied. For the first time, with the complete spectroscopic survey of 11,692galaxies in the 9hr Deep Lensing Survey field, clusters can be identified boththrough the convergence map peaks and through velocity distributions. 20 massiveclusters with velocity dispersions >500 km/s and 12 weak lensing peaks have werefound in the DLS. We will investigate the bias in mass vs. baryon selections bycompleting XMM-Newton observations of this sample. For the X-ray brighter clus-ters we will compare the total masses computed from cluster velocitydispersions, from gravitational lensing, and from robust, X-ray measured, mass proxies.

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.
