| Abstract | Using a theoretical model for the pulsed non-thermal emission above 1 keV andextending until the gamma-ray domain, we have fitted all known spectra ofgamma-ray pulsars and obtained estimates for their flux levels in X-rays. Wehave chosen several objects for which their estimate exceeds 3e-13 erg/cm2 s at10 keV. Based on the success of the model when contrasted with pulsars for whichX-ray and gamma-ray measurements exist, we propose to observe these candidatesto enlarge the sample of non-thermal X-ray detected pulsars, which till nowcontains only a handful members. |

| 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. |
