Abstract
Gamma-ray measurements from GeV to PeV energies have provided us with a wealth of information on diffuse emission and sources in the Universe lately. With improved spatial and temporal resolutions together with real-time multimessenger astronomy, the modeling of 3D cosmic-ray transport becomes more and more important to explain the data. Here, we will give a compact summary of how cosmic-ray propagation in very different astrophysical environments like the Sun, Milky Way, and active galaxies can be constrained by combining 3D modeling with the propagation software CRPropa with gamma-ray measurements.
