Cosmic-ray propagation in the turbulent intergalactic medium

Understand

Cosmic rays (CRs) may be used to infer properties of intervening cosmic magnetic fields.

• Conversely, understanding the effects of magnetic fields on the propagation of high-energy CRs is crucial to elucidate their origin.
• In the present work we investigate the role of intracluster magnetic fields on the propagation of CRs with energies between $10^{16}$ and $10^{18.5}$ eV.
• We look for possible signatures of a transition in the CR propagation regime, from diffusive to ballistic.
