|Title||A746: A Smorgasbord of Particle Acceleration|
|Author||Dr Christine Jones|
|Description||Abell 746 is a unique system hosting a spectacular double radio relic, a possible radio halo, and two radio bright diffuse regions to the east of the cluster. With our proposed XMM-Newton and JVLA observations, along with existing low frequency radio data, we will (1) understand the origin of complex diffuse radio sources; (2) probe the underlying particle acceleration mechanism; (3) characterize the properties of the shocks responsible for these sources; (4) determine the merger scenario by comparison with simulations; and (5) study polarization properties of the relics and the magnetization of the intracluster medium through Faraday analysis.|

|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.
