ABSTRACT
The North Polar Spur (NPS) is a region of strong diffuse X-ray emission that extends in a wide arc from l,b =25deg,10deg to 330deg,75deg. Conventional wisdom says that the NPS is the limb-brightened edge of the Loop I superbubble, roughly centered on, and likely powered by the Sco-Cen OB association, placing it at a distance of 100-200 pc. However, it has also been seen as a supershell centered on the Galactic center, and the implications for the plasma and energy involved are extreme. We propose to determine the location of the NPS using a series of overlapping observations of the southern terminus. Comparison with the Galactic distribution of X-ray absorbing material will allow us to determine if the NPS is absorption bounded, and by which ISM features, thus revealing the distance to the NPS.

PAPERS
Authors marked in red are (co-)investigators in the proposal

Classification of papers are:
- CLASS 1:   papers that present specific XMM-Newton observations
- CLASS 2: papers that refer to published XMM-Newton results with complementary observations, follow-up analysis, or theoretical analysis
- CLASS 3: further deliveries which resulted from the program and which are made available to the community (e.g. source catalogues, processed images or spectra in public data base)
- CLASS 4: comments and suggestions from PI
