Abstract | 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 ofgalaxy clusters has important consequences for cosmology. Moreover, since theunder-luminous clusters are expected to be undergoing major mergers, this sampleprovides a great opportunity to quantify energy re-distribution among thermaland non-thermal particles, study heat transport and enrichment evo- lution. Werequest 175ks of XMM-Newton time to cover the 11 clusters which lackgood-quality observations. With these data, we will determine their dynamicalstate and history, examine the processes responsible for gas heating, andmeasure the impact of such powerful mergers on cosmological studies. |

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. |
