Propagation of ultrahigh energy cosmic rays in extragalactic magnetic fields: a view from cosmological simulations
Original language description
We use the CRPROPA code to simulate the propagation of ultrahigh energy cosmic rays (with energy >= 10(18) eV and pure proton composition) through extragalactic magnetic fields that have been simulated with the cosmological ENZO code. We test both primordial and astrophysical magnetogenesis scenarios in order to investigate the impact of different magnetic field strengths in clusters, filaments and voids on the deflection of cosmic rays propagating across cosmological distances. We also study the effect of different source distributions of cosmic rays around simulated Milky Way-like observers. Our analysis shows that the arrival spectra and anisotropy of events are rather insensitive to the distribution of extragalactic magnetic fields, while they are more affected by the clustering of sources within an similar to 50 Mpc distance to observers.
