In the attempt to explain the energy spectrum of cosmic rays, it is currently unclear where the Galactic component ends and where the contribution of the extragalactic component begins. An additional component is needed for the transition region between the two. In this project, the question of whether the termination shock of our own Galaxy could provide this extra component will be evaluated. Finally, a combined model of how the observed particle fluxes can be explained with a combination of Galactic and extragalactic cosmic rays will be derived, in particular with respect to their spectral evolution, composition and anisotropy.

在试图解释宇宙射线的能谱时，目前还不清楚银河系成分在哪里结束，河外成分的贡献在哪里开始。两者之间的过渡区需要一个额外的组件。在这个项目中，我们自己的银河系的终端冲击是否可以提供这个额外的组件的问题将被评估。最后，一个合并的模型，如何观察到的粒子通量可以解释与银河系和河外宇宙射线的组合，特别是关于他们的光谱演化，组成和各向异性。
