Signatures of Ultra-High Energy Cosmic Ray Composition from Propagation of Nuclei in Intergalactic Photon Fields
We present a calculation of nuclei propagation with energies above 1018 eV in the intergalactic photon field. The calculation is based on a Monte Carlo approach for the nucleus-photon interaction as well as the intergalactic magnetic field. We then assume that the Ultra-High Energy Cosmic Rays (UHECR) are nuclei which are emitted from extra-galactic point sources. Four bumps are found in the en...
متن کاملTime Delays in Cosmic Ray Propagation
Cosmic Rays (CR) travel at speeds essentially indistinguishable from the speed of light. However whilst travelling through magnetic fields, both regular and turbulent, they are delayed behind the light since they are usually charged particles and their paths are not linear. Those delays can be so long that they are an impediment to correctly identifying sources which may be variable in time. Fu...
متن کاملThe Mysterious Ultrahigh Energy Cosmic Ray Clustering
We examine the correlation between compact radio quasars (redshifts in the range z = 0.3−2.2) and the arrival direction of ultrahigh energy cosmic rays forming clusters. Our Monte Carlo simulation reveals a statistically significant correlation on the AGASA sample: the chance probability of this effect being less than 1%. The implications of this result on the origin of ultrahigh energy cosmic ...

متن کاملIntergalactic Propagation of Uhe Cosmic Rays
We discuss the intergalactic propagation of ultra-high-energy cosmic rays (UHECRs) with energies E > ∼ 10 eV. We consider the propagation of UHECRs under the influence of the energy-dependent deflection by a weak random magnetic field in the intergalactic medium and energy losses by photo-pion and pair production. We calculate arrival spectra taking full account of the kinematics of photo-pion ...
