The HGPS revealed a point-like source we consider to be of high interest: HESSJ1828-099. It is one of only 17 sources in the HGPS with an angular size0.07deg. This source is unique in the sense that it does not seem to haveapparent associations at lower energies and it is not located in highly confusedregions such as the Galactic Center. What is the nature of HESS J1828-099 ? Isit perhaps a young PWN, with dim counterparts? Is it maybe a gamma-ray binary? Asupernova remnant? We aim at identifying the nature of the point-likeunidentified source HESS J1828-099 in thecontext of a MWL campaign (X-rays andradio). We will prove the non-thermal emission scenario making use ofthese three different frequencies.

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.
