The composite unidentified source HESS J1843-033

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 XMMNewton to perform followupobservations on one of the brightest newly discovered sources, HESS J1843033,to identify its possible Xray counterparts. An offset PWN is one of thepossible explanations for HESS J1843033, 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. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
