Investigation of cosmic ray deflections in cosmic magnetic fields for the source hypothesis of starburst galaxies — •Paula Bigalke, Teresa Bister, Martin Erdmann, Martin Urban, and Marcus Wirtz — III. Physikalisches Institut A, RWTH Aachen University, Deutschland

Magnetic field deflections of cosmic rays provide rigidity dependent patterns which can be exploited in anisotropy studies on small and intermediate scales. The galactic magnetic field leads to coherent displacements in the arrival directions and small scale turbulent components in extragalactic and galactic regions induce a symmetric scatter around the source directions.

Recently, an indication for anisotropy in the arrival directions of UHECRs correlating with the flux patterns of the Starburst Galaxy source catalogue was found. In order to further study this Starburst Galaxy scenario we investigate several observables sensitive to patterns originating from deflections in cosmic magnetic fields.
