Abstract The error box of the high-energy gamma-ray source 3EG J1809-2328 contains anX-ray and radio synchrotron nebula emerging from a point X-ray source that isundoubtedly a radio-quiet pulsar. Since the gamma-rays from 3EG J1809-2328 arevariable on time scales of months to years, they may be of a qualitativelydifferent origin from the usual magnetospheric emission from rotation-poweredpulsars. We propose to discover the pulsations in X-rays in order to evaluatewhether the gamma-rays can be powered by the spin-down luminosity of the pulsar.The resulting pulse ephemeris will also be used in conjunction with future GLASTdata to determine what fraction of the gamma-rays are pulsed, and what remainingfraction can be powered by diffuse mechanisms involving pulsar wind nebulae.

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.
