Abstract (from CDS):

The serendipitous discovery of an unidentified extended TeV γ-ray source close to the galactic plane named HESS J1303-631 at a significance of 21 standard deviations is reported. The observations were performed between February and June 2004 with the HESS stereoscopic system of Cherenkov telescopes in Namibia. HESS J1303-631 was discovered roughly 0.6° north of the binary system PSR B1259-63/SS2883, the target object of the initial observation campaign which was also detected at TeV energies in the same field of view. HESS J1303-631 is extended with a width of an assumed intrinsic Gaussian emission profile of σ=(0.16±0.02)° and the integral flux above 380GeV is compatible with constant emission over the entire observational period of (17±3)% of the Crab Nebula flux. The measured energy spectrum can be described by a power-law dN/dE∼E^–Γ with a photon index of Γ=2.44±0.05_stat±0.2_syst. Up to now, no counterpart at other wavelengths is identified. Various possible TeV production scenarios are discussed.
