| Description | During the first year of operation, the Fermi gamma-ray observatory has detected two new transient GeV sources in the Galactic plane. The nature of these Galactic gamma-ray transients is currently not known. We propose XMM-Newton ToO observations of new transients discovered with the Fermi LAT in the Galactic plane. The XMM-Newton observations will enable us to more accurately localize the transients, identify counterparts at other wavelengths, determine their X-ray to gamma-ray flux ratio, measure their X-ray spectrum, and characterize their variability and decay time scale. This proposal is part of a multiwavelength program that includes observations at radio and TeV energies. |

| 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. |
