Description Chandra and XMM are extending the minimum luminosity to which X-ray clusters can be detected and analyzed at intermediate redshifts, probing masses characteristic of poor clusters. Strong lensing systems with image separations in the range 6"-16" are starting to be detected thus opening also with this technique a new window of exploration in this crucial mass range. An unprecedented opportunity of X-ray-lensing comparison is therefore opening in an unexplored lower mass regime compared to the one of massive clusters. Therefore, we propose a snapshot survey of 5 promising strong lensing poor clusters to secure their X-ray fluxes. Deep follow-up exposures with Chandra will then be proposed for detailed analysis of the mass profile.

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.
