Description The most massive galaxy clusters are extremely valuable study objects for a wide range of astrophysical and cosmological studies. In our completed all-sky X-ray cluster survey we found 7 rare massive galaxy clusters with masses above 6.4e14 solar masses at z=0.25-0.5 (the sweet spot for gravitational lensing studies), which have not been observed in X-ray pointed observations so far. We propose these objects for observations with XMM-Newton and the three most interesting systems for HST observations, with a main goal to characterise their use as gravitational lensing telescopes. In addition these observations complete an important sample of massive clusters to be used for a range of cosmological studies.

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.
