Studies of the UHECR propagation in the Galactic Magnetic Field

Understand

We present the results of simulations of the ultra-high energy cosmic ray (UHECR) propagation in the Galactic magnetic field (GMF).

• Different assumptions on the large-scale GMF structure and/or primary particle lead to distinctly different deflection patterns of the highest energy cosmic rays (CR).
• The GMF modifies the exposure of an UHECR experiment to the extragalactic sky.
• We estimated these effects for the Pierre Auger experiment.
