|Title||Pulse Searches of Two Radio Quiet GeV Pulsars Associated with TeV Sources|
|Author||Dr Mallory Roberts|
|Description||There are several likely gamma-ray pulsars in EGRET error boxes which are probably associated with known TeV sources, but radio searches have failed to detect pulsations from them. Direct searches for gamma-ray pulsations of the brightest EGRET sources using Fermi are proving quite successful. However, to understand the emission mechanisms, pulsations at other wavelengths are critical. Here we propose XMM-Newton studies of two such sources: GeV J1825-1310 (the Eel) and GeV J1907+0557, with the primary goal of detecting X-ray pulsations using the PN in small window mode. Both have extended X-ray nebula whose spatial and spectral properties will be studied using the MOS imagers.|

|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.
