Abstract | We request observing time towards the recently discovered unidentified, variableCOMPTEL gamma-ray source. There are three ROSAT sources already detected in thisregion, but only with 8 photons each, such that spectral analysis of them hasnot been yet possible. This observation will allow to obtain their spectrum,distinguish between their diffuse or point-like character, and analyze theirtemporal behavior. This observation will also allow to search for X-raycounterparts of five radio sources detected nearby and uncover any other X-rayemitter lying in the field of view of the EPIC cameras which would be plausiblyrelated with the COMPTEL detection. |

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. |
