要旨

The H.E.S.S. experiment (High Energy Stereoscopic System) is an array of imaging Cherenkov telescopes for the detection of γ-rays in the energy domain above 100 GeV. Its improved sensitivity and angular resolution in comparison to previous instruments and the large field of view of 5 degrees makes H.E.S.S. perfectly suited for a survey of the galactic plane. We report on a scan of the inner part of the Galactic plane in very high energy γ-rays with the H.E.S.S telescope system. The Galactic plane between longitude 330 deg and 30 deg and Galactic latitude -3 deg to +3 deg was observed for a total of 230 hours, reaching an average flux sensitivity of 3% of the Crab Nebula at energies above 200 GeV. Several unknown sources of very high energy γ-ray emission were found at a high statistical significance. We will present results for these new sources, along with a discussion on possible counterparts in other wavelength bands.
