Title A Spectral survey of X-ray selected high redshift clusters

Description GT- The primary aim is to measure the X-ray temperatures of high redshift
(0.32<z<0.6) clusters of galaxies and determine the evolution of the cluster
temperature function. This will test (a) models of the growth of structure in
the Universe, and (b) give an estimate of the importance of non-gravitational
heating (or cooling) of the ICM, e.g. by supernova-driven galaxy winds at an
early epoch, as predicted in the preheating scenario (which explains the
currently observed luminosity evolution at high luminosities and lack of
evolution at lower luminosities).

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.
