G8.7-0.1 is a middle-aged Galactic supernova remnant (SNR) located inside thestar-forming region W30. It shows various signs of high energy activity, seenthrough thermal X-ray radiation as well as through nonthermal high energy (E >100 MeV) and very high energy (E > 100 GeV) emission. However, a concise pictureof the different components seen in the SNR remains elusive, perhaps owing tothe large angular size and the location in a crowded and absorbed area on theGalactic plane. We propose to extend our XMM-Newton observations on the NorthernSNR shell, with the aim of constraining the shock conditions that led to thepeculiar combination of low ionisation state and lack of morphological shockfeatures.

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.
