| Abstract | All TeV-emitting supernova remnant (SNR) shells that have been detected so farshow strong non-thermal X-ray synchrotron emission, evidencing the presence ofsupra-TeV electrons. Here, we propose to observe the Southern part of the newlyidentified TeV SNR shell HESS J1534-571 with XMM-Newton in an exploratory 30 kspointing, to pin down the X-ray emission from the object. Previous Suzakupointings on the Northern part of the shell have revealed a surprisingly lowlevel of X-ray synchrotron emission from this part of the object, which mayindicate that HESS J1534-571 differs from the other known TeV SNRs andpotentially exhibits hadronic TeV emission. The proposed XMM-Newton observationwill scrutinize this result before strong conclusions can be drawn. |

| 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. |
