Origin of the light cosmic ray component below the ankle

Popis výsledku v původním jazyce

The origin and nature of the ultrahigh energy cosmic rays remains a mystery. However, considerable progress has been achieved in past years due to observations performed by the Pierre Auger Observatory and Telescope Array. Above 10(18) eV the observed energy spectrum presents two features: a hardening of the slope at similar to 10(18.6) eV, which is known as the ankle, and a suppression at similar to 10(19.6) 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. Also, the anisotropy information is consistent with an extragalactic origin of this light component that would dominate the spectrum below the ankle.
