    • High-energy pulsar models: developments and new questions 

      Venter, C.; Harding, A.K. (Wiley-VCH Verlag, 2014)
      The past few years have seen a major advance in observational knowledge of high-energy (HE) pulsars. The Fermi Large Area Telescope (LAT) and AGILE have increased the number of known γ-ray pulsars by an order of magnitude, ...
    • Modeling drift along the heliospheric wavy neutral sheet 

      Burger, Renier Adriaan (IOP Publishing, 2012)
      Drift along the wavy heliospheric neutral sheet is believed to play an important role in cosmic-ray modulation and can explain the peaked versus flat intensity profiles during consecutive solar magnetic epochs. Modulation ...
    • Possible evidence for a fisk-type heliospheric magnetic field, 1: analyzing Ulysses/Ket electron observations 

      Burger, Renier Adriaan; Engelbrecht, Nicholas Eugene; Ferreira, Stephanus Esaias Salomon; Potgieter, Marthinus Steenkamp; Sternal, O.; Fichtner, H.; Heber, B.; Kopp, A.; Scherer, K. (IOP Publishing, 2011)
      The propagation of energetic charged particles in the heliospheric magnetic field is one of the fundamental problems in heliophysics. In particular, the structure of the heliospheric magnetic field remains an unsolved ...
    • Relativistic positron-electron-ion shear flows and application to gamma-ray bursts 

      Liang, Edison; Fu, Wen; Boettcher, Markus; Smith, Ian; Roustazadeh, Parisa (IOP Science, 2013)
      We present particle-in-cell simulation results of relativistic shear flows for hybrid positron–electron–ion plasmas and compare to those for pure e+e− and pure e− ion plasmas. Among the three types of relativistic shear ...
