| Description | We propose XMM-Newton observations of the X-ray brightest cooling-flow clusters with bright gravitational arcs, identified from the ROSAT XBACS/BCS lensing study. All of our targets have been (or wil be) observed for us with Chandra, HST and ground-based optical observatories. Our primary aim is to extend the X-ray temperature, X-ray gas mass and total mass profiles measured with Chandra out to large radii. In combination, the X-ray and optical (strong and weak lensing) data will be used to explore the nature of the dark matter in the clusters and to constrain cosmological parameters from the variation of the X-ray gas mass fraction. Our targets are the X-ray brightest, dynamically relaxed lensing clusters which have not yet been observed with XMM-Newton. |

| 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. |
