Two young low-surface brightness SNRs were recently discovered by members of ourgroup in the W80 complex. The discovery was made using the Canadian GalacticPlane Survey, and confirmed with the ROSAT All Sky Survey. We propose a 70 ksecexposure with EPIC to observe these, and the two previously known radio SNRs inthe region, in order to: 1) characterize their X-ray emission, and 2) search fortheir collapsed cores and/or plerions. The low-surface brightness, high columndensity, size, age, and lack of X-ray spectral information, make XMM the bestsatellite to perform this study. A detailed X-ray imaging, spectroscopic andtiming analysis of this poorly studied sample will illuminate our understandingof neutron star properties, supernova evolution, and cosmic ray acceleration.

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.
