In a survey of the Galactic plane performed in 2007 with the High EnergyStereoscopic System (H.E.S.S.) many new sources have been discovered and most ofthem are still unidentified. We propose to use XMM-Newton to perform follow-upobservations on one of the brightest newly discovered sources, HESS J1843-033,to identify its possible X-ray counterparts. An offset PWN is one of thepossible explanations for HESS J1843-033, but this hypothesis is still underinvestigation. The aim is to obtain the morphological and spectral informationof the possible counterparts in helping to understand the emission mechanism ofthis 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.
