Ultra-high Energy Cosmic Ray Propagation in the Universe
This paper summarizes recent developments in the study of the propagation of ultra-high energy cosmic ray protons or nuclei in the Universe, with emphasis on the consequences of energy losses and on the influence of extra-galactic magnetic fields.
متن کاملPropagation of ultra high energy cosmic rays
We briefly describe the energy loss processes of ultrahigh energy protons, heavier nuclei and gamma rays in interactions with the universal photon fields of the Universe. We then discuss the modification of the accelerated cosmic ray energy spectrum in propagation by the energy loss processes and the charged cosmic ray scattering in the extragalactic magnetic fields. The energy lost by the ultr...
متن کاملUltra High Energy Cosmic Ray Accelerators
The surprising lack of a high energy cutoff in the cosmic ray spectrum at the highest energies together with an apparently isotropic distribution of arrival directions have strongly challenged most models proposed for the acceleration of ultra high energy cosmic rays. Young neutron star winds may be able to explain the mystery. We discuss this recent proposal after summarizing the observational...
متن کاملUltra High-Energy Cosmic Ray Observations
The year 2007 has furnished us with outstanding results about the origin of the most energetic cosmic rays: a flux suppression as expected from the GZK-effect has been observed in the data of the HiRes and Auger experiments and correlations between the positions of nearby AGN and the arrival directions of trans-GZK events have been observed by the Pierre Auger Observatory. The latter finding ma...
متن کاملCosmic Magnetic Fields and Their Influence on Ultra-High Energy Cosmic Ray Propagation
We discuss the influence of large scale cosmic magnetic fields on the propagation of hadronic cosmic rays above 10 eV based on large scale structure simulations. Our simulations suggest that rather substantial deflection up to several tens of degrees at 10 eV are possible for nucleon primaries. Further, spectra and composition of cosmic rays from individual sources can depend on magnetic fields...
