Revisiting the role of the streaming instability for the cosmic-ray spectrum in the GeV to TeV range
Linh Han Thanh, Julien Dörner, Horst Fichtner +2
A complete understanding of the cosmic-ray energy spectrum remains a challenge to theory that must be met by comprehensive modeling efforts. One of these is the subject of the pres…
The impact of Solar magnetic field configurations on the production of gamma rays at the Solar disk
Julien Dörner, Frederic Effenberger, Horst Fichtner +4
The Sun produces a steady signal of high-energy gamma rays through interactions of Galactic cosmic rays (GCRs) with its atmosphere. Observations with Fermi-LAT and HAWC have reveal…
Anisotropic Cosmic Ray Transport in strong MHD Turbulence due to Magnetic Mirroring and Resonant Curvature Scattering
Jeremiah Lübke, Frederic Effenberger, Mike Wilbert +2
The transport of cosmic rays through turbulent astrophysical plasmas still constitutes an open problem. Building on recent progress, we study the combined effect of magnetic mirror…
Superdiffusion of energetic particles at shocks: A Lévy Flight model for acceleration
Sophie Aerdker, Lukas Merten, Frederic Effenberger +2
In the Heliosphere, power-law particle distributions are observed e.g. upstream of interplanetary shocks, which can result from superdiffusive transport. This non-Gaussian transpor…
Numerical Modeling of Time Dependent Diffusive Shock Acceleration
Sophie Aerdker, Lukas Merten, Julia Becker Tjus +3
Motivated by cosmic ray (CR) re-acceleration at a potential Galactic Wind Termination Shock (GWTS), we present a numerical model for time-dependent Diffusive Shock Acceleration (DS…
