|Title||Measuring and constraining turbulence in galaxy clusters using XMM-RGS|
|Author||Dr Jeremy Sanders|
|Description||We have demonstrated for the first time the ability of the XMM-Newton RGS instruments to measure or place limits on turbulence in galaxy clusters. We propose to observe five targets chosen to provide excellent limits on turbulence in galaxy clusters. They are bright, have cool cores and are point-like with respect to the XMM-RGS and should have bright narrow emission lines. We expect to obtain limits or measurements between 340-480 km-s (90% uncertainty) in these clusters. These are the best direct limit on turbulence in the intracluster medium we can obtain before the launch of ASTRO-H and IXO. An important secondary objective will be to study AGN feedback in luminous cluster cores. We will be able to determine whether AGN feedback matches cooling to better than 10%.|

|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.
