|Title||X-ray spectroscopy of cooling flow clusters|
|Author||Prof Johan Bleeker|
|Description||The properties of 3 cooling flow clusters, i.e. A 262, A 496 and Hydra A, with a range of mass accretion rate are studied. All clusters have a medium angular size allowing adequate spatially resolved spectroscopy with XMM-EPIC of the entire cluster with a single pointing. Some targets yield good quality RGS spectra that potentially provide important spectral details in the band below 1 keV, in particular on the presence and nature of X-ray absorbing material. XMM will not only provide accurate measurements of the radial temperature and abundance distribution but will also allow a search for hard X-ray tails and resonance scattering effects, providing a detailed insight in the physical processes in the hot cluster gas.|

|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.
