| Abstract | We propose to use EPIC to map the error boxes of four middle-to-low latitude galactic EGRET sources. Their X-ray counterparts could be radio quiet isolated neutron stars similar to Geminga. Our gamma-ray targets have been carefully selected amongst the unidentified EGRET sources in the 3 CG catalogue on the basis of their having a relatively good positioning, a flat spectrum and on the basis of their galactic location. We have deliberately avoided the sources very close to the plane to focus on sources still at low galactic latitude, but outside the plane. We believe that this choice should make it easier to pinpoint the neutron star candidates similar to Geminga. |

| 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. |
