| Abstract | Calibration of scaling relations between weak lensing mass and X-ray observablesis a powerful tool for cluster count cosmology. Recent studies show thatenergetics due to feedback from active galaxies and star formation becomessignificant at group and low-mass cluster levels, implying that low mass systemsmight follow a different scaling than massive clusters. Here we propose toextend the X-ray coverage of low mass clusters in the CFHTLS field by a factorof approximately 4 in order to measure the effects of feedback on clusterscaling relations. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
