    • Millisecond pulsars and pulsar wind nebulae as sources of gamma rays and cosmic rays 

      Venter, Christo (North-West University, 2008)
      Our main aim was to implement a fully 3D General Relativistic (GR) frame-dragging polar cap (PC) millisecond pulsar (MSP) model as a numerical code, and constrain it using multiwavelength and cosmic-ray data. We also ...
    • Modelling the evolution of pulsar wind nebulae 

      Vorster, Michael Johannes (2014)
      This study focusses on modelling important aspects of the evolution of pulsar wind nebulae using two different approaches. The first uses a hydrodynamic model to simulate the morphological evolution of a spherically-symmetric ...
    • A search for optical counterparts of the complex Vela X system 

      Marubini, Enos Takalani (North-West University (South Africa) , Potchefstroom Campus, 2012)
      The pulsar wind nebula (PWN) associated with the Vela pulsar, Vela X, is a complex system visible in radio, X-ray and y-ray wavelengths, but not in the optical wavelength. Knowledge of the brightness and structure of the ...
    • Spectral modelling of H.E.S.S.- detected pulsar wind nebulae 

      Van Rensburg, Carlo (North-West University (South Africa) , Potchefstroom Campus, 2016)
      In the last decade, ground-based Imaging Atmospheric Cherenkov Telescopes have discovered about 175 very-high-energy (VHE; E > 100 GeV) gamma-ray sources, with more to follow with the development of H.E.S.S. II and CTA. ...
