We propose a mini-survey of unclassified Fermi sources from the 2FGL catalog.Using an intelligent parameter selection, we have identified a sub-sample thatis likely to be dominated by pulsars. We aim to identify 8 new gamma-ray pulsarsvia their X-ray counterparts and expand the population of pulsars detected inboth gamma-rays and X-rays. The existing limited data hint at an intriguingchange in the slope of the L(Edot) dependence at Edot=10^35-10^36 erg/s, both inX-rays and gamma-rays. By identifying more pulsars in both gamma- and X-rays,especially at lower Edot, we will be able to confirm the existence of thosebreaks and investigate their origin. We will also identify new X-ray brightpulsars suitable for detailed study using the prudent snap-shot approach.

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.
