Abstract Increasing the sample of neutron star-SNR associations is needed to study thedynamics and evolution of supernova explosions of massive stars and to unveilthe properties of their collapsed cores. A handful low-surface brightness SNRswere recently discovered with the Canadian Galactic Plane Survey (CGPS). AllSNRs are believed to be the remnants of core-collapse explosions, young, andharbor X-ray point sources. We here propose to observe 2 of these SNRs withXMM-Newton in order to primarily detect and characterize their X-ray emission.Their low-surface brightness, high column density, size, age, and lack of X-rayspectral information make XMM the best satellite to date to perform this study.

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.
