|Title||SEARCH FOR X-RAY PULSATIONS FROM THE GAMMA-RAY SOURCE 3EG J1809-2328|
|Author||Prof JULES HALPERN|
|Description||The error box of the high-energy gamma-ray source 3EG J1809-2328 contains an X-ray and radio synchrotron nebula emerging from a point X-ray source that is undoubtedly a radio-quiet pulsar. Since the gamma-rays from 3EG J1809-2328 are variable on time scales of months to years, they may be of a qualitatively different origin from the usual magnetospheric emission from rotation-powered pulsars. We propose to discover the pulsations in X-rays in order to evaluate whether 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 GLAST data to determine what fraction of the gamma-rays are pulsed, and what remaining fraction can be powered by "diffuse" mechanisms involving pulsar wind nebulae.|

|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.
