Description We propose to observe a Planck SZ selected, complete sample of 15 X-ray under- luminous galaxy clusters with XMM-Newton. This largely unstudied population of galaxy clusters has important consequences for cosmology. Moreover, since the under-luminous clusters are expected to be undergoing major mergers, this sample provides a great opportunity to quantify energy re-distribution among thermal and non-thermal particles, study heat transport and enrichment evo- lution. We request 175ks of XMM-Newton time to cover the 11 clusters which lack good-quality observations. With these data, we will determine their dynamical state and history, examine the processes responsible for gas heating, and measure the impact of such powerful mergers on 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.
