Modelling the transport of cosmic rays (CRs) in the heliosphere represents a global
challenge in the field of heliophysics, in that such a study, if it were to be performed from first …

In cosmic ray physics extensive progress has been made in recent years, both concerning
theory and observation. The vast details in direct, indirect and secondary detections on the …

We give a brief review of the origin and acceleration of cosmic rays (CRs), emphasizing the
production of CRs at different stages of supernova evolution by the first-order Fermi shock …

Energetic particles represent an important component of the plasma in the heliosphere.
They range from particles accelerated at impulsive events in the solar corona and at large …

In this review, an overview of the recent history of stochastic differential equations (SDEs) in
application to particle transport problems in space physics and astrophysics is given. The …

This paper presents the current wall-embedded Langmuir probe system installed on the
Tokamak à Configuration Variable (TCV), as well as the analysis tool chain used to interpret …

This paper summarizes the results obtained by the team “Heliosheath Processes and the
Structure of the Heliopause: Modeling Energetic Particles, Cosmic Rays, and Magnetic …

Test particle codes indicate that electron dynamics due to interactions with low amplitude
incoherent whistler mode‐waves can be adequately described by quasi‐linear theory …

We propose and test a method to interpolate sparsely sampled signals by a stochastic
process with a broad range of spatial and/or temporal scales. To this end, we extend the …

The transport of energetic particles in the presence of magnetic turbulence is an important
but unsolved problem of space physics and astrophysics. Here, we aim at advancing the …
