Numerical and experimental evidence for a new interpretation of residence times in space

A. Vogt, N. E. Engelbrecht, B. Heber +2

We investigate the energy dependence of Jovian electron residence times, which allows for a deeper understanding of adiabatic energy changes that occur during charged particle tran…

Assessing Uncertainties in the Predicted Very-High-Energy Flux of Globular Clusters in the Cherenkov Telescope Array Era

Hambeleleni Ndiyavala-Davids, Christo Venter, Andreas Kopp +1

Terzan 5 is the only Galactic globular cluster that has plausibly been detected in the very-high-energy range. Stacking upper limits by H.E.S.S. on the integral -ray flux of a p…

On the residence-time of Jovian electrons in the inner heliosphere

A. Vogt, N. E. Engelbrecht, R. D. Strauss +3

Jovian electrons serve as an important test-particle distribution in the inner heliosphere and have been used extensively in the past to study the (diffusive) transport of cosmic r…

The effect of turbulence strength on meandering field lines and Solar Energetic Particle event extents

T. Laitinen, F. Effenberger, A. Kopp +1

Insights into the processes of Solar Energetic Particle (SEP) propagation are essential for understanding how solar eruptions affect the radiation environment of near-Earth space.…

The millisecond pulsar contribution to the rising positron fraction

Christo Venter, Andreas Kopp, Alice K Harding +2

Pair cascades from millisecond pulsars (MSPs) may be a primary source of Galactic electrons and positrons that contribute to the increase in positron flux above 10 GeV as observed…

Solar energetic particle access to distant longitudes through turbulent field-line meandering

T. Laitinen, A. Kopp, F. Effenberger +2

Context. Current solar energetic particle (SEP) propagation models describe the effects of interplanetary plasma turbulence on SEPs as diffusion, using a Fokker-Planck (FP) equatio…
