GZK photons as UHECR above 10 eV
“GZK photons” are produced by extragalactic nucleons through the resonant photoproduction of pions. We present the expected range of the GZK photon fraction of UHECR, assuming a particular UHECR spectrum and primary nucleons, and compare it with the minimal photon fraction predicted by Top-Down models. The Pierre Auger Observatory [1] may prove photon fractions in the Ultra-High Energy Cosmic R...
متن کاملAnti-GZK effect in UHECR spectrum
Abstract. In this paper we discuss the anti-GZK effect that arises in the framework of the diffusive propagation of Ultra High Energy (UHE) protons. This effect consists in a jump-like increase of the maximum distance from which UHE protons can reach the observer. The position of the jump is independent of the Intergalactic Magnetic Field (IMF) strength and depends only on the energy losses of ...
متن کاملMagnetic horizons of UHECR sources and the GZK feature
We study the effect of random extra-galactic magnetic fields on the propagation of protons of energy larger than 10 eV. We show that for reasonable field values (in the 100 nG range) the transition between diffusive and ballistic regimes occurs in the same energy range as the GZK cutoff (a few 10 eV). The usual interpretation of the flux reduction above the GZK energy in terms of a sudden reduc...
متن کاملSuper-GZK Photons from Photon-Axion Mixing
We show that photons with energies above the GZK cutoff can reach us from very distant sources if they mix with light axions in extragalactic magnetic fields. The effect which enables this is the conversion of photons into axions, which are sufficiently weakly coupled to travel large distances unimpeded. These axions then convert back into high energy photons close to the Earth. We show that ph...
متن کاملCosmogenic photons strongly constrain UHECR source models
With the newest version of our Monte Carlo code for ultra-high-energy cosmic ray (UHECR) propagation, CRPropa 3, the flux of neutrinos and photons due to interactions of UHECRs with extragalactic background light can be predicted. Together with the recently updated data for the isotropic diffuse gamma-ray background (IGRB) by Fermi LAT, it is now possible to severely constrain UHECR source mode...
