Propagation of ultra-high energy protons in the nearby universe
We present a new calculation of the propagation of protons with energies
above eV over distances of up to several hundred Mpc. The calculation
is based on a Monte Carlo approach using the event generator
SOPHIA for the simulation of hadronic nucleon-photon interactions and a
realistic integration of the particle trajectories in a random extragalactic
magnetic field. Accounting for the proton scattering in the magnetic field
affects noticeably the nucleon energy as a function of the distance to their
source and allows us to give realistic predictions on arrival energy, time
delay, and arrival angle distributions and correlations as well as secondary
particle production spectra.Comment: 12 pages, 9 figures, ReVTeX. Physical Review D, accepte
