Detection of very-high-energy-ray emission from the vicinity of PSR B1706 44 and G 343.1 2.3 with H.E.S.S.

The -ray pulsar PSR B1706−44 and the adjacent supernova remnant (SNR) candidate G 343.1−2.3 were observed by H.E.S.S. during a dedicated observation campaign in 2007. As a result of this observation campaign, a new source of very-high-energy (VHE; E> 100 GeV) -ray emission, HESS J1708−443, was detected with a statistical significance of 7 � , although no significant point-like emission was detected a t the position of the energetic pulsar itself. In this paper, the morphologic al and spectral analyses of the newly-discovered TeV source are presented. The centroid [� ]
