We propose to observe the two Abell clusters of galaxies A13 and A4038 in whichwe have identified filamentary radio relic sources. Sensitive XMM-Newton EPICobservations will allow us to detect an excess thermal X-ray emission componentthat may result from hydrodynamical activities associated with the relicstructure as well as inverse Compton emission produced when the samerelativistic electrons which produce the radio relic emission scatter CosmicMicrowave Background photons. These radiation components will be detected byXMM-Newton spatially, by finding X-ray structures which agree with the radiostructures, and spectroscopically by the additional spectral features mixed withthe thermal emission of the intracluster medium.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
