- 29.08. Benedikt Schroer (U Chicago): T ransport Transport of Galactic Cosmic-Ray Nuclei
Abstract: C...Understanding the cosmic-ray transport properties in our Galaxy is of utmost importance for many different observations. Using a well-motivated, semi-analytical model, we prove that a single population of cosmic-ray sources accelerating all elements with the same slope is able to explain the available data. We further test the self-consistency of our model by investigating particle transport on intermediate scales with a special focus on the escape of accelerated particles into the interstellar medium. These escaping particles are able to excite the non-resonant streaming instability inside a flux tube. As a result, one expects efficient self-confinement of high-energy particles, which we confirm by performing 2D and 3D hybrid particle-in-cell simulations with the code dHybridR. These bubbles of self-confinement might introduce some modifications to the previously described model of transport on Galactic scales.
