Contributions from nearby pulsars to the local cosmic ray electron spectrum
(Elsevier, 2008)
PSR J0437-4715 is one of the closest millisecond pulsars (MSPs) to Earth, lying at a distance of _140 pc. This pulsar has a characteristic age of 4.9 Gyr and a relatively low spindown power of _1034 ergs/s. During its ...

Ekonometriese modelle in finansiële risiko
(AOSIS, 2008)
This paper provides an overview of the contributions by prof JH Venter to financial risk and volatility modelling, estimation and forecasting. Venter's research is based on the classical GARCH model which he refines in ...

Discovery of very-high-energy gamma-ray emission from the vicinity of PSR J1913+1011 with HESS
(EDP Sciences, 2008)
The HESS experiment, an array of four Imaging Atmospheric Cherenkov Telescopes with high sensitivity and large field-of-view, has been used to search for emitters of very-high-energy (VHE, >100 GeV) $\gamma$-rays along the ...
The role of radial perpendicular diffusion and latitude dependent acceleration along the solar
(Elsevier, 2008)
A numerical model, based on Parker’s transport equation, describing the modulation of anomalous cosmic rays and containing diffusive shock acceleration is applied. The role of radial perpendicular diffusion at the solar ...
