|Title||HESS J1507-622: an unique unidentified source off the Galactic Plane|

|Description||Galactic VHE gamma-ray sources in the inner Galaxy H.E.S.S. survey cluster within 1 deg in latitude around the Galactic plane. HESS J1507-622 instead is unique, since located at latitude of -3.5 degrees. No plausible counterparts have been detected; and, given its position and hence the absorption almost one order of magnitude lower, it is very surprising to not see any counterparts especially at X-rays. Its latitude implies that it is either within about 1 kpc or is located well off the Galactic plane. The models reflect the uniqueness of this object: a leptonic scenario would locate the source at very large distan- ces, while it would be very close in hadronic scenarios. The high sensitivity of XMM-Newton will shed light on the nature of this mysterious source.|

|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.
