Abstract	We propose the observations of 3 sources detected in Third Fermi High EnergyCatalog(3FHL; E > 10GeV) that have an X-ray counterpart inside the Fermi error reg ionbut are still unidentified.These sources, lying on the Galactic plane (BII <10 deg), could hide a new classof Galactic gamma-ray emitters. We ask to observe thesesources with XMM-Newton for 60 ks in total ,nominal time, plus 40 % to avoid thebackground radiation problem (http://xmmtools.cosmos.esa.int/external xmm_user_support/documentation/AOpolicy/node34.html),in order to study the ene rgetic and morphology in the X rays, allowing us the identification of sites of extreme particle acceleration.

Mission Description	The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
