Title The origin of the diffuse X-ray emission along the galactic ridge

Author Prof Jurgen Schmitt
Description Active stars-binaries (ASB) have been proposed as a significant constituent of the diffuse background observed along the galactic ridge.Previous X-ray studies of the ridge and its sources have always been hampered by the fact that the searches for the presumed source population had to be carried out in low energy spectral bands and hence the spectral properties of the constituent populations had to be extrapolated. With the XMM-Newton slew survey (XSS) a sufficiently deep hard X-ray survey has become available. Among the XSS hard band sources we have filtered out a set of 33 targets which allow detailed EPIC spectroscopy in the r^ant 3 - 7 keV region and 6.7 keV iron line complex and allow to construct a representative sample of the presumed galactic ridge ASB population.

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.
