In this manuscript we present a new approach for the numerical solution of the Galactic Cosmic Ray propagation problem. We introduce a method using advanced contemporary numerical algorithms while retaining the general complexity of other established codes. In this paper we present the underlying numerical scheme in conjunction with tests showing the correctness of the scheme. Finally we show the solution of a first example propagation problem using the new code to show its applicability to Galactic Cosmic Ray propagation.

  1. Time-dependent cosmic-ray escape from wind bubbles: hard spectra formation

    astro-ph.HE 2026-06 unverdicted novelty 5.0 of 10

    Numerical modeling of time-dependent cosmic-ray advection and diffusion in spherically symmetric wind bubbles shows escaping spectra harder than E^{-2} during the wind-driven phase, with low-energy suppression dependi...

  2. The Cherenkov Telescope Array view of the Galactic Center region

    astro-ph.HE 2019-08 conditional novelty 4.0 of 10

    Simulations of the planned CTA Galactic Center survey show that the observatory should reconstruct the central source spectrum with percent-level statistical precision and detect faint hour-long flares.
