X-Ray and Radio Emission of the Galactic Supernova Remnant G7.7-3.7

We propose to analyse the Xray emission of the Galactic SNR G7.73.7, a virgul21.radio SNR with a peculiar filamentary morphology with bright knots. The Xrayemission, 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 Xray sourcecoincident with a pointlike radio structure. Combining the high quality XMM andradio data will allow us to investigate the nature of the compact Xray objectand discern between different scenarios which could give rise to the peculiarmorphology. The high spectral and spatial resolution Xray data covering thecomplete extent of SNR will also be used to constrain its age and energetics. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
