Description A survey of the Galactic plane performed in 2004 with the H.E.S.S. instrument allowed to double the number of known VHE gamma-ray sources. Re-observations and improvements in the analysis sensitivity in 2005 have permitted to discover new unidentified sources. We propose to use XMM-Newton to search for two of these sources for which no obvious counterparts were found at other wavelenghts. The sensitivity of XMM-Newton above a few keV is required to detect possible counterparts despite the obscuration by the gas in the Galactic plane. Morphological and spectral information on the sources would help to understand the nature and the emission mechanisms of these unidentified VHE gamma-ray sources.

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.
