Time-dependent cosmic-ray escape from wind bubbles: hard spectra formation
Lukas Merten, Sophie Aerdker, Enrico Peretti
Overview: Wind-driven bubbles are dynamic systems that can accelerate cosmic rays, depending on their physical properties, up to very high energies. We investigate how a time-depen…
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…
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…
Modeling Cosmic-Ray Transport: A CRPropa based stochastic differential equation solver
Lukas Merten, Sophie Aerdker
We present a new code that significantly extends CRPropa's capabilities to model the ensemble averaged transport of charged cosmic rays in arbitrary turbulent magnetic fields. The…
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…
CRPropa 3.2: a public framework for high-energy astroparticle simulations
Sophie Aerdker, Rafael Alves Batista, Julia Becker Tjus +16
CRPropa is a Monte Carlo framework for simulating the propagation of (ultra-) high-energy particles in the Universe, including cosmic rays, gamma rays, electrons, and neutrinos. It…
