Description HESS J1731-347 is only the third known TeV-emitting SNR with a pure nonthermal X-ray spectrum. Together with RX J1713.7-3946 and RX J0852.0-4622, the sources are outstanding because of their TeV luminosity and their synchrotron-only X-ray emission. These SNRs are considered prime candidates for hadronic cosmic ray acceleration. But currently, it is highly debated if the TeV emission is really tracing hadronic cosmic rays, or if X-rays and TeV photons are emitted basically just by the same cosmic ray electron population. With this proposal, we ask for 55 ksec of XMM-Newton observing time on the western part of the HESS J1731-347 shell, in order to resolve the synchrotron-emitting filaments in this part of the remnant and to bring the high resolution mapping of the source to near completion.

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.
