    • Cosmic ray modulation beyond the heliopause: a hybrid modeling approach 

      Strauss, R.D.; Potgieter, M.S.; Ferreira, S. E. S.; Fichtner, H.; Scherer, K. (IOP Science, 2013)
      Results from a newly developed hybrid cosmic ray (CR) modulation model are presented. In this approach, the transport of CRs is computed by incorporating the plasma flow from a magnetohydrodynamic model for the heliospheric ...
    • A new SNR with TeV shell-type morphology: HESS J1731-347 

      Venter, Christo; Vorster, Michael Johannes; Büsching, Ingo; De Jager, Ocker Cornelis (EDP Sciences, 2011)
      Aims. The recent discovery of the radio shell-type supernova remnant (SNR), G353.6-0.7, in spatial coincidence with the unidentified TeV source HESS J1731−347 has motivated further observations of the source with the High ...
    • Search for dark matter annihilation signals from the fornax galaxy cluster with HESS 

      Abramowski, A.; Büsching, I.; De Jager, O.C.; Sheidaei, F.; Venter, C.; Vorster, M. (IOP Publishers, 2012)
      The Fornax galaxy cluster was observed with the High Energy Stereoscopic System for a total live time of 14.5 hr, searching for very high energy (VHE; E > 100GeV) γ -rays from dark matter (DM) annihilation. No significant ...
