X-ray study of the likely PWN associated with a new VHE gamma-ray source

The newly discovered veryhighenergy (VHE) gammaray source HESS J1718385 liesin close proximity to the energetic pulsar PSR,J17183825. This object appearsto belong to a growing class of .offset. pulsar wind nebula (PWN). So far nosensitive Xray observations of this region have taken place. If confirmed byXMM observations, this would be the first PWN discovered in VHE gammarays. Thepredicted Xray flux is sufficient for detailed spectral and morphologicalstudies of this object with XMM.
