|Title||Constraining Cluster Evolution at z > 1 with the SpARCS-RCS Cluster Surveys|
|Author||Dr Erica Ellingson|
|Description||We propose XMM-EPIC observations of 3 clusters at high redshift from the SpARCS survey in order to constrain the evolution of X-ray scaling relations. An important difference between this survey and others is that by using galaxy-selected clusters, we can construct a sample which is unbiased in its gas properties. Each of these clusters has been detected by three methods: as a highly significant overdensity of red sequence galaxies, spectroscopically as a cluster with numerous confirmed members and velocity dispersions > 500 km-s, and as a faint, but extended X-ray source. Our proposed observations will yield accurate gas temperatures, enabling these clusters to be used in a study of the evolution of the cluster gas, galaxy and mass scaling relations to z>1.|

|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.
