|Determining the effects of baryonic feedback on galaxy cluster scaling relations
|Mr Kimmo Kettula
|Calibration of scaling relations between weak lensing mass and X-ray observables is a powerful tool for cluster count cosmology. Recent studies show that energetics due to feedback from active galaxies and star formation becomes significant at group and low-mass cluster levels, implying that low mass systems might follow a different scaling than massive clusters. Here we propose to extend the X-ray coverage of low mass clusters in the CFHTLS field by a factor of approximately 4 in order to measure the effects of feedback on cluster scaling relations.

|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.
