Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with $$E \ge 6 \times 10^{19}$$ E ≥ 6 × 10 19 eV by analyzing cosmic rays with energies above $$E \ge 5 \times 10^{18}$$ E ≥ 5 × 10 18 eV arriving within an angular separation of...
