Modelling magnetic turbulence with log-normal intermittency by continuous cascades

Autor: Jeremiah Lübke, Frederic Effenberger, Horst Fichtner, Rainer Grauer

The transport of cosmic rays in turbulent magnetic fields is commonly investigated by solving the Newton-Lorentz equation of test particles in synthetic turbulence fields. These fields are typically generated from superpositions of Fourier modes with

Solar Energetic Particles (SEP) events are interesting from a scientific perspective as they are the product of a broad set of physical processes from the corona out through the extent of the heliosphere, and provide insight into processes of particl

We study the process of nonlinear shock acceleration based on a nonlinear diffusion–advection equation. The nonlinearity is introduced via a dependence of the spatial diffusion coefficient on the distribution function of accelerating particles. Thi

Connecting solar flare hard X-ray spectra to in-situ electron spectra using RHESSI and STEREO/SEPT observations

Autor: Alexander Warmuth, Nina Dresing, Maximilian Bruedern, Ludwig Klein, Frederic Effenberger, Sophie Musset, Lindsay Glesener

In-situ observations of solar energetic particle events are determined by a combination of acceleration, injection, and transport processes which are often hard to disentangle. However, the energy spectrum of impulsive electron events is believed to

A Primer on Focused Solar Energetic Particle Transport: Basic physics and recent modelling results

Autor: Du Toit Strauss, Jabus van den Berg, Frederic Effenberger

The basics of focused transport as applied to solar energetic particles are reviewed, paying special attention to areas of common misconception. The micro-physics of charged particles interacting with slab turbulence are investigated to illustrate th
