|Title||Searching for X-ray non-thermal emission in a radio-bright galaxy group|
|Author||Dr Francois Mernier|
|Description||We propose a deep XMM-Newton observation (210 ks including overheads) of MRC 0116+111. This unique galaxy group is known to host a remarkably bright extended diffuse radio emission - likely witnessing of a past extreme AGN feedback episode, along with a moderate X-ray luminosity and gas temperature. Since its radio-X-ray flux ratio is among the highest ever reported for a diffuse source, it is an ideal target to search for non-thermal, inverse-Compton (IC) X-ray emission. Assuming that the average group magnetic field is less than 10 microG, the proposed exposure will constrain the properties of the thermal gas glowing below 2 keV and detect significantly the non-thermal emission, which dominates beyond that energy.|

|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.
