Identification of HESS J1303-631 as a Pulsar Wind Nebula through gamma-ray, X-ray and radio observations

The previously unidentified very high-energy (VHE; E 100 GeV) \gamma-ray source HESS J1303-631, discovered in 2004, is re-examined including new data from the H.E.S.S. Cherenkov telescope array. Archival data from the XMM-Newton X-ray satellite and from the PMN radio survey are also examined. Detail... Full description

Significant energy-dependent morphology of the \gamma-ray source is detected with high-energy emission (E 10 TeV) positionally coincident with the pulsar PSR J1301-6305 and lower energy emission (E 2 TeV) extending \sim 0.4^{\circ} to the South-East of the pulsar. The spectrum of the VHE source can be described with a power-law with an exponential cut-off N_{0} = (5.6 \pm 0.5) X 10^{-12} TeV^-1 cm^-2 s^-1, \Gamma = 1.5 \pm 0.2) and E_{\rm cut} = (7.7 \pm 2.2) TeV.
