Time-dependent cosmic ray modulation in the outer heliosphere: Signatures of a heliospheric asymmetry and model predictions along Voyager 1 and 2 trajectories
Rex Manuel, Stefan Ferreira, Marius Potgieter
A two-dimensional, time-dependent numerical model is used to calculate the modulation of cosmic rays in the heliosphere. Computations are compared to spacecraft observations in the…
Time-Dependent Modulation of Cosmic Rays in the Heliosphere
Rex Manuel, Stefan Ferreira, Marius Potgieter
The time-dependent modulation of galactic cosmic rays in the heliosphere is studied by computing intensities using a time-dependent modulation model. By introducing recent theoreti…
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…
