Last few years, we have presented various results of high-resolutionspectroscopies of SNRs with the RGS. Although a large amount of the archivaldata over the past twenty years is available and most of the notable SNRs havebeen observed with the RGS, several intriguing remnants are still not observed.A recent comprehensive systematic analysis of SNRs revealed that a clearcorrelation between their morphologies and supernova types. We, however, foundtwo outliers in the correlation diagram\: 0548-70.4 and 0104-72.3, which areminor LMC/SMC SNRs but have anomalous abundance pattern and peculiarmorphologies. We thus propose to observe these SNRs with the RGS to give aconclusive result on their origin and nature.

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.
