Currently pulsar wind nebulae (PWNe) and supernova remnants (SNRs) are believedto be the dominant source of Galactic cosmic rays. The observed radio, X-ray,and TeV emission from SNR G5.7-0.1 suggests it is a source of cosmic rays, butits non-thermal emission is incompatible with either a SNR or a PWN. Insteadthis source requires that 1) either electrons are currently escaping a PWN, or2) the SNR shell is a rare site of highly efficient electron and/or protonacceleration, and/or 3) the unlikely spatial coincidence of a luminous diffusenon-thermal X-ray source and a thermal X-ray SNR. With the requested 30 ks XMMobservation, we will determine what is accelerating particles in this enigmaticobject.

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.
