The effect of general relativistic frame dragging on millisecond pulsar visibility for the H.E.S.S. telescope
(North-West University, 2004)It has been noted by several authors that General Relativistic frame dragging in rotating neutron stars is a first order effect which has to be included in a self-consistent model of pulsar magnetospheric structure and ... -
Millisecond pulsars and pulsar wind nebulae as sources of gamma rays and cosmic rays
(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 ... -
Search for Lorentz invariance breaking with a likelihood fit of the PKS 2155-304 flare data taken on MJD 53944
(Elsevier, 2011)Several models of Quantum Gravity predict Lorentz Symmetry breaking at energy scales approaching the Planck scale (∼1019 GeV). With present photon data from the observations of distant astrophysical sources, it is possible ... -
Spectral modelling of H.E.S.S.- detected pulsar wind nebulae
(North-West University (South Africa), 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. ...
