Implications of gamma-ray and neutrino observations on source models of ultrahigh energy cosmic rays
Original language description
The origin and nature of the ultrahigh energy cosmic rays (UHECRs) are still unknown. However, great progress has been achieved in past years due to the observations performed by the Pierre Auger Observatory and Telescope Array. Above 1018 eV the observed energy spectrum presents two features: a hardening of the slope at about 1018.7 eV, which is known as the ankle and a suppression at approximately 1019.6 eV. The composition inferred from the experimental data, interpreted by using the current high energy hadronic interaction models, seems to be light below the ankle, showing a trend to heavier nuclei for increasing values of the primary energy.
