HESS J1848-018 is an unidentified TeV gamma-ray source located in the Galacticplane near the massive star formation region W43. It has been suggested that thelatter may power the TeV emission, although the detailed physical mechanism isyet unknown. We have identified an X-ray source from archival ASCA and Swiftdata that coincides with HESS J1848-018. We propose 48ks of XMM observations tocharacterize the nature of this X-ray source. If it is a new pulsar wind nebulaor a supernova remnant, then it could easily explain the TeV emission, as seenin many other Galactic TeV sources. On the other hand, if the X-ray source isnot a physically reasonable counterpart, this would provide some support to theassociation between the star formation region and the TeV source.

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.
