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