Abstract The supernova remnant (SNR) CTB109 presents a unique laboratory for studying theinteraction of SNRs with interstellar clouds: one half of the remnant has expanded unimpeded into a low-density medium and the other half has expanded directly into a dense molecular cloud. The nearly ideal viewing geometry allowsthe two halves to be cleanly separated. The spectrum of the outer shell, the bright interior emission, and the shock/cloud interface will be well characterized by the three proposed 15 ks pointings. We will determine the ionization structure as a function of position behind the shock, as well asmeasuring the temperature and abundances. Despite being observed by every majorX-ray observatory, there still exists much uncertainty in the physical ..

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.
