| Description | The Fermi satellite opened new horizons in gamma-ray astronomy with the detection of already 1451 sources in the first 11 months of science operations of the LAT instrument. While some of them are identified as gamma-ray pulsars and AGNs, other are just associated with potential gamma-ray emitters. However, many of the LAT sources have no potential association yet. Their nature is unknown and can only be investigated through multi-wavelength observations. Here we propose to map the error boxes of selected LAT sources in X-rays with XMM and in the optical with the VLT. On the basis of their X-ray/optical properties, for each LAT source we will then be able to single out the X-ray source which is a potential gamma-ray emitter. |

| 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. |
