|Title||The Thermal Structure of Distant Cooling Flows|
|Author||Dr Richard Mushotzky|
|Description||GT- RGS spectra are required to distinguish two- or three-temperature plasmas from true multi-phase media in cooling flow clusters. We propose to observe two very massive cooling flows at redshift about one-quarter -- sufficiently distant so that the highly peaked cooling flow region inside 200 kpc appears approximately point-like to the XMM mirrors. 50 ksec XMM exposures of these objects yield >15-20 line photons for 15-25 features,thus enabling the thermal structure to be disentangled.|

|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.
