The cosmic-ray ground-level enhancements of 29 September 1989 and 20 January 2005
H. Moraal, R. A. Caballero-Lopez, K. G. McCracken
Enhancements of the comic-ray intensity as observed by detectors on the ground have been observed 71 times since 1942. They are due to solar energetic particles accelerated in the…
The pulse shape of cosmic-ray ground-level enhancements
H. Moraal, K. G. McCracken, R. A. Caballero-Lopez
Enhancements of the comic-ray intensity as observed by detectors on the ground have been observed 71 times since 1942. They are due to solar energetic particles accelerated in the…
The Effect of Diffusion on the Particle Spectra in Pulsar Wind Nebulae
M. J. Vorster, H. Moraal
A possible way to calculate particle spectra as a function of position in pulsar wind nebulae is to solve a Fokker-Planck transport equation. This paper presents numerical solution…
Spatial Development of Energetic Particle Spectra in Pulsar Wind Nebulae
Michael Vorster, Harm Moraal
The evolution of the non-thermal emission emitted by pulsar wind nebulae is generally calculated using spatially-independent particle transport models. Although useful, these model…
