Description GT- The bright X-ray feature North Polar Spur (NPS) is the result of a supernova
remnant shock interacting with the inner walls of the giant supershell around
the Sco-Cen OB association. It has been shown that the shock from a 10^{51} erg
explosion within the Loop I superbubble can heat the dense shell to temperatures
of 3-4 10^6 K, giving rise to the observed X-ray emission. The shock running
into the density gradient in the wall is rapidly decelerated, and strong cooling
can lead to non-equilibrium effects like .overionization. Using EPIC pn, we can
study emission line ratios in the 0.3 - 2.0 keV range and thus determine the
plasma state. Three adjacent 20 ksec observations will cover the steepest
gradient in X-ray brightness.

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.
