New results are presented: at about 1.3 ×1019 eV , the spectral index changes from 2.51 ±0.03 (stat ) ±0.05 (syst ) to 3.05 ±0.05 (stat ) ±0.10 (syst ) , evolving to 5.1 ±0.3 (stat ) ±0.1 (syst ) beyond 5 ×1019 eV , while no significant dependence of spectral features on the declination is seen in the accessible range. These features of the spectrum can be reproduced in models with energy-dependent mass composition. The energy density in cosmic rays above 5 ×1018 eV is [5.66 ±0.03 (stat ) ±1.40 (syst ) ]×1053 erg Mpc-3 .STAMPAenFeatures of the Energy Spectrum of Cosmic Rays above 2.5 ×10 18 eV Using the Pierre Auger ObservatoryArticle10.1103/PhysRevLett.125.1211062-s2.0-85092348814WOS:000569641300005https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.125.121106http://arxiv.org/abs/2008.06488v22020PhRvL.125l1106AFIS/05 - ASTRONOMIA E ASTROFISICA
