H.E.S.S. observations of the supernovae remnant RCW 86 — •Stefan Hoppe for the H.E.S.S. collaboration — Max-Planck-Institut fuer Kernphysik, Heidelberg, Germany

The shell-type supernova remnant (SNR) RCW 86 - possibly associated with the historical supernova SN 185 - was observed over the past three years with the High Energy Stereoscopic System (H.E.S.S.), an array of four atmospheric-Cherenkov telescopes located in Namibia. The multi-wavelength properties of RCW 86, e.g. weak radio emission and North-East X-ray emission almost entirely consisting of synchroton radiation, resemble those of two VHE emitting SNRs RX J1713.7-3946 and RX J0852-4622. The H.E.S.S. observations reveal a new extended source of VHE (>100 GeV) γ-ray emission. The morphological and spectral properties of this new source will be presented.
