Description Combining X-ray and gravitational lensing methods is currently the most powerful way in which to trace mass on large scales. We have recently conducted a lensing study of a z=0.16 supercluster, and have mapped its mass and resolved an intracluster filament. A comparison of the lensing map and galaxy distribution has revealed variation in the cluster M-L ratios and galaxy properties, and significant misalignments between light and mass. We propose to match our unique lensing dataset with the exquisite sensitivity of XMM-Newton to trace the diffuse X-ray gas and answer the question: where are the baryons? The proposed observations provide the key to resolving the puzzling nature of this system and will open up a new field beyond the traditional study of galaxy clusters.

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.
