Detecting the pulsars that power Galactic TeV sources is the key tounderstanding the origin of those that remain unidentified. We have twoexcellent new X-ray candidates to search for pulsations, from XMM observationsof the Integral source IGR J18490-0000 coincident with the compact TeV sourceHESS J1849-000, and XMMU J162703.03-491232.7 found within the TeV extent of HESSJ1626-490. Both are bright, non-thermal point sources with a faint nebula. Allcharacteristics of these objects resemble those of young, energetic pulsars.Finding the expected pulsations will allow us to determine their energetics,critical for understanding the luminosity and size of their TeV nebulae.

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.
