Modelling cosmic-ray transport: magnetised versus unmagnetised motion in astrophysical magnetic turbulence
Jeremiah Lübke, Patrick Reichherzer, Sophie Aerdker +4
Cosmic-ray transport in turbulent astrophysical environments remains a multifaceted problem and, despite decades of study, the impact of complex magnetic field geometry -- evident…
Towards the Composition of sub-PeV Cosmic Rays at IceCube
Julian Saffer
With the implementation of a low-energy trigger, the surface array of the IceCube Neutrino Observatory is able to record cosmic-ray induced air showers with a primary energy of a f…
CRPropa 3.3: Toward a Unified Multi-Messenger Framework from GeV to ZeV Energies
Sophie Aerdker, Rafael Alves Batista, Julia Becker Tjus +11
We present CRPropa 3.3, the latest release of the publicly available Monte Carlo framework for simulating the propagation of high-energy particles in astrophysical environments. Th…
Spectra for the Vacuum Cherenkov Effect in Astrophysical Electromagnetic Cascades with Lorentz Invariance Violation
Andrey Saveliev, Rafael Alves Batista, Feodor Mishin
Lorentz invariance violation is a feature of several quantum gravity models in which Lorentz symmetry is broken at high energies, possibly leading to changes in particle behavior a…
Combined dark matter search towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS
LAT Collaboration, S. Abdollahi, L. Baldini +586
Dwarf spheroidal galaxies (dSphs) are excellent targets for indirect dark matter (DM) searches using gamma-ray telescopes because they are thought to have high DM content and a low…
Cosmic-ray transport in inhomogeneous media
Robert J. Ewart, Patrick Reichherzer, Shuzhe Ren +6
A theory of cosmic-ray transport in multi-phase diffusive media is developed, with the specific application to cases in which the cosmic-ray diffusion coefficient has large spatial…
