|Title||Complete X-ray Observations of an Off-Center Region in Coma|
|Author||Dr Ann Hornschemeier|
|Description||We propose two 105 ks XMM observations of an off-center region in the Coma cluster to study X-ray emission from normal galaxies and to construct a galaxy X-ray Luminosity Function (XLF). We have demonstrated the feasibility of studying galaxies in Coma during a Chandra Cycle 5 pilot program (60 ks) in this same area. The region has an optical LF measured down to dwarf galaxy limits; the XMM XLF will help us constrain the possible suppression of X-ray emission due to ICM ram pressure in this field. We will also study the evolution of X-ray emission from galaxies using the well-determined SF histories of galaxies in this region (thanks to the superb multiwavelength data available in this field , i.e., GALEX, Spitzer, SDSS).|

|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.
