| Description | We propose to observe three rich clusters of galaxies to look for significant dark subclusters that are not seen in optical images but are inferred from weak lensing mass maps. Our candidates come from the largest weak lensing study yet of 39 x-ray selected clusters. Detecting these subclusters and measuring their properties like mass, temperature and metallicity would constitute the first comprehensive study of its kind, and provide important clues to the nature of stochastic biasing and galaxy formation. |

| 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. |
