The detection of ejecta emission in mature supernova remnants can allow thedetermination of explosion type. This is important for understanding the genesisand evolution of the interstellar medium in galaxies. The Large Magellanic Cloudoffers an excellent sample of SNRs at a known distance with little extinction.We propose to observe three remnants in the LMC, 0520-69.4, 0528-69.2, and DEML241, with XMM-Newton. The spectral resolution of XMM-Newton should allow us toseparate reverse shock heated ejecta emission from ISM material heated by theouter blast wave. By performing spatially- resolved spectroscopy on the limb andcentral regions, our goal is to find evidence of ejecta and determine theirchemical composition.

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.
