Time-dependent Modeling of Pulsar Wind Nebulae
M. J. Vorster, O. Tibolla, S. E. S. Ferreira +1
A spatially independent model that calculates the time evolution of the electron spectrum in a spherically expanding pulsar wind nebula (PWN) is presented, allowing one to make bro…
Numerical simulations of composite supernova remnants for small pulsar wind nebulae
M. J. Vorster, S. E. S. Ferreira, O. C. de Jager +1
Composite supernova remnants consist of a pulsar wind nebula located inside a shell-type remnant. The presence of a shell has implications on the evolution of the nebula, although…
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…
Time-dependent modelling of pulsar wind nebulae
M. J. Vorster, O. Tibolla, S. E. S. Ferreira +1
A spatially-independent model that can be used to calculate the temporal evolution of the electron/ positron spectrum in a spherically expanding pulsar wind nebula is presented. Th…
Are most of the VHE gamma-ray unidentified sources relic PWNe?
Omar Tibolla, Michael Vorster, Sarah Kaufmann +2
The evolution of Pulsar Wind Nebulae (PWNe) plays a crucial role in interpreting the very high energy (VHE; > 10^11 eV) gamma-ray unidentified sources; and moreover it represents t…
