Abstract The interaction between SNRs and molecular clouds causes immediate heating andchanges the chemical composition of the surrounding gas, emitting thermal andnon-thermal X-rays, OH maser lines, and gamma-rays. However, what causes thepartial overlap among maser-emitting SNRs, EGRET source SNRs, SNRs withparticular X-ray properties such as mixed-morphology SNRs is still unclear. CTB37A is a radio-bright Galactic SNR, and is accompanied by OH masers and EGRETsource. As the best target for the study of the SNRs in the dense conditions, wepropose the wide-band and large effective area observation of CTB 37A withXMM-Newton.

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.
