    • Discovery and follow-up studies of the extended, off-plane, VHE gamma-ray source HESS J1507-622 

      Acero, F.; Busching, I.; Davids, I.D.; De Jager, O.C.; Holleran, M.; Raubenheimer, B.C.; Venter, C.; H.E.S.S. Collaboration (EDP Sciences, 2011)
      Context. The detection of gamma-rays in the very-high-energy (VHE) range (100 GeV−100 TeV) offers the possibility of studying the parent population of ultrarelativistic particles found in astrophysical sources, so it is ...
    • Discovery of gamma-ray emission from the shell-type supernova remnant RCW 86 with HESS 

      Aharonian, F.; Busching, I.; De Jager, O.C.; Holleran, M.; Raubenheimer, B.C.; Venter, C.; H.E.S.S. Collaboration (IOP Publishing, 2009)
      The shell-type supernova remnant (SNR) RCW 86, possibly associated with the historical supernova SN 185, with its relatively large size (about 40' in diameter) and the presence of nonthermal X-rays is a promising target ...
    • HESS upper limit on the very high energy gammay-ray emission from the globular cluster 47 Tucanae (Research Note) 

      Aharonian, F.; Busching, I.; Davids, I.D.; De Jager, O.C.; Holleran, M.; Raubenheimer, B.C.; Venter, C.; H.E.S.S. Collaboration (EDP sciences, 2009)
      Observations of the globular cluster 47 Tucanae (NGC 104), which contains at least 23 ms pulsars, were performed with the HESS telescope system. The observations lead to an upper limit of F(E > 800 GeV) < 6.7 × 10−13 cm−2 ...
    • Localizing the VHE y-ray source at the galactic centre 

      Acero, F.; Busching, I.; Davids, I.D.; De Jager, O.C.; Holleran, M.; Raubenheimer, B.C.; Venter, C.; H.E.S.S. Collaboration (Oxford University Press, 2010)
      The inner 10 pc of our Galaxy contains many counterpart candidates of the very high energy (VHE; >100 GeV) γ -ray point source HESS J1745−290. Within the point spread function of the H.E.S.S. measurement, at least three ...
    • Spatially resolved XMM-Newton analysis and a model of the nonthermal emission of MSH 15-52 

      Schöck, F.M.; Busching, I.; De Jager, O.C.; Vorster, M.J.; Eger, P. (EDP Sciences, 2010)
      We present an X-ray analysis and a model of the nonthermal emission of the pulsar wind nebula (PWN) MSH 15 − 5 2 . We analyzed XMM-Newton data to obtain the spatially resolved spectral parameters around the pulsar PSR ...
