Description HESS J1848-018 is an unidentified TeV gamma-ray source located in the Galactic plane near the massive star formation region W43. It has been suggested that the latter may power the TeV emission, although the detailed physical mechanism is yet unknown. We have identified an X-ray source from archival ASCA and Swift data that coincides with HESS J1848-018. We propose 48ks of XMM observations to characterize the nature of this X-ray source. If it is a new pulsar wind nebula or a supernova remnant, then it could easily explain the TeV emission, as seen in many other Galactic TeV sources. On the other hand, if the X-ray source is not a physically reasonable counterpart, this would provide some support to the association between the star formation region and the TeV source.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
