| Zusammenfassung |
| Various experiments show that the arrival directions of multi-TeV cosmic rays
show significant anisotropies at small angular scales. It was recently argued
that this small scale structure may arise naturally by cosmic ray diffusion
in a large-scale cosmic ray gradient in combination with deflections in local
turbulent magnetic fields. We show via analytical and numerical methods that
the non-trivial power spectrum in this setup is a direct consequence of
Liouville's theorem and can be related to properties of relative diffusion. |
