Abstract The Fermi, AGILE, and EGRET gamma-ray telescopes have discovered more than adozen transient sources of GeV gamma rays near the Galactic plane. Only six ofthese sources have been identified at other wavelengths, four as novae, a newclass of GeV gamma-ray sources. The physical nature of the other Galacticgamma-ray transients is still unknown. These GeV transients may potentiallyrepresent a new class of gamma-ray emitting objects. We propose XMM-Newton ToOobservations of new transients discovered with the Fermi LAT in the Galacticplane. The XMM-Newton observations will enable us to more accurately localizethe transients, identify counterparts at other wavelengths, determine theirX-ray flux and spectrum, and characterize their variability.

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.
