Discovery of a pulsar wind nebula associated with IGR J18490 0000
The IBIS/ISGRI camera on board the INTEGRAL observatory has performed a full survey of the Galactic disk in the hard X ray regime from 20 keV up to several hundred of keV with an unprecedented sensitivity and angular resolution in this energy range. Among a large number of compact binary systems, this survey has revealed a number of unidentified objects. Using X ray observations of one of these sources, IGR J18490 0000, we discovered a rather bright non thermal pointlike object surrounded by an extended diffuse nebula compatible with the Integral position. The morphology and spectral behaviour of both pointlike and extended X ray emissions are reminiscent of a young pulsar wind nebula of a few thousands years. The H.E.S.S. Array has observed the region and we present the TeV detection of the object. We compare this object to other PWNe visible in the hard X ray and TeV regime.
