We propose a 40 ksec XMM observation of the supernova remnant G359.1-0.5. Wewill measure the column density towards G359.1-0.5, and thus determine whetherthis remnant may be located at the same distance as, and be associated with, thepulsar known as the Mouse. We will also study the morphology and spectralvariations of this mixed-morphology remnant. Mixed-morphology, or thermalcomposite, remnants show a center-filled morphology that cannot be understood inthe standard picture of supernova evolution. We aim to constrain the mechanismsof X-ray production from the center of this remnant, identifying whether thermalconduction, cloudlet evaporation, metallicity gradients or other effects areprimarily responsible for the observed center-filled morphology.

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.
