We propose to analyse the X-ray emission of the Galactic SNR G7.7-3.7, a virgul21.radio SNR with a peculiar filamentary morphology with bright knots. The X-rayemission, as detected by ROSAT and ASCA, seems to be confined to the east of theradio shell, with its intensity increasing at the location of a bright radiofeature near the limb of the SNR and, interestingly, a compact X-ray sourcecoincident with a point-like radio structure. Combining the high quality XMM andradio data will allow us to investigate the nature of the compact X-ray objectand discern between different scenarios which could give rise to the peculiarmorphology. The high spectral and spatial resolution X-ray data covering thecomplete extent of SNR will also be used to constrain its age and energetics.

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.
