    • Discovery of extended VHE Y-ray emission from the vicinity of the young massive stellar cluster Westerlund 1 

      Abramowski, A.; Büsching, I.; De Jager, O.C.; Sheidaei, F.; Venter, C.; Vorster, M. (EDP Science, 2012)
      Aims. Results obtained in very-high-energy (VHE; E≥100GeV) γ-ray observations performed with the H.E.S.S. telescope array are used to investigate particle acceleration processes in the vicinity of the young massive stellar ...
    • Discovery of the VHE gamma-ray source HESS J1832−093 in the vicinity of SNR G22.7−0.2 

      Abramowski, A.; Böttcher, M.; Casanova, S.; Davids, I.D.; Krüger, P.P.; Pekeur, N.W.; Sushch, I.; Venter, C.; Vorster, M. (Oxford University Press, 2015)
      The region around the supernova remnant (SNR) W41 contains several TeV sources and has prompted the HESS Collaboration to perform deep observations of this field of view. This resulted in the discovery of the new very high ...
    • On cosmic ray modulation beyond the heliopause: where is the modulation boundary? 

      Ferreira, Stephanus Esaias Salomon; Potgieter, Marthinus Steenkamp; Scherer, K.; Fichtner, H.; Strauss, Roelf du Toit; Fahr, H.-J. (IOP Publications, 2011)
      Two of the paradigms in modeling the transport of galactic cosmic rays are that the modulation boundary is the heliopause and that the local interstellar spectra are identical to the galactic cosmic ray spectra. Here we ...
