Features of the energy spectrum of cosmic rays above $2.5\times 10^{18}$ eV using the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Aab, P. Abreu +380

We report a measurement of the energy spectrum of cosmic rays above $2.5\times 10^{18}$ eV based on $215,030$ events. New results are presented: at about $1.3\times 10^{19}$ eV…
