The influence of extragalactic magnetic fields on the propagation of cosmic rays from Centaurus A

Abstract

The motion of different chemical composition of ultra high energy cosmic rays in the galactic magnetic fields with taking into account the extragalactic magnetic field was considered. The ultra high energy events registered by the AUGER observatory in the sky region near Centaurus A were investigated. It is shown that in the case when the extragalactic magnetic field is taken into account some of these events could originate from Centaurus A, but it leads to expanding of sky region of possible source localization.
