Description We propose to observe the hot plasma-cold cloud X-ray emitting interface region surrounding the Coalsack Nebula. Such an interface will provide a nearly unique insight into the physical parameters of transition regions, which are a feature of most models of the interstellar medium but are not observed (except in active SNR shock fronts). The motivation for the observation is three-fold, to (1) verify the existence of the X-ray bright transition region (..the halo..) as observed with relatively low exposure in ROSAT data, (2) determine the origin of the X-ray emitting plasma, and (3) determine the physical state of the plasma. Specifically, these observations will provide the characteristics of the hot side of the Hot-Cool interface.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
