Unravelling the mystery of the unidentified TeV source HESSJ1614-518 with XMM

We propose XMMNewton observations (60ks in 2x30ks pointings) of theunidentified TeV gammaray source HESSJ1614518. HESSJ1614518 is extended withradius virgul0.4deg. The gammaray morphology of HESSvirgulJ1614518 appears complex, withan arc of emission extending south and westwards. Despite our extensive search,we find no obvious counterparts. These include several pulsars, all withinsufficient spin down power and also several catalogued Xray sources (ROSATand EXOSAT surveys). XMMNewton observations will permit a detailed search forXray counterparts, further studies of the known Xray sources, and play a vitalrole in establishing the electronic or hadronic nature of the parent particlesof this enigmatic TeV source. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
