Origin of the light cosmic ray component below the ankle
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 ${10}^{18}\text{ }\text{ }\mathrm{eV}$ the observed energy spectrum presents two features: a hardening of the slope …
