abstract = {A promising energy range to look for angular correlations between cosmic rays of extragalactic origin and their
sources is at the highest energies, above a few tens of EeV (1 EeV ≡ 1018 eV). Despite the flux of these particles
being extremely low, the area of ∼3000 km2 covered at the Pierre Auger Observatory, and the 17 yr data-taking
period of the Phase 1 of its operations, have enabled us to measure the arrival directions of more than 2600 ultrahigh-
energy cosmic rays above 32 EeV. We publish this data set, the largest available at such energies from an
integrated exposure of 122,000 km2 sr yr, and search it for anisotropies over the 3.4π steradians covered with the
Observatory. Evidence for a deviation in excess of isotropy at intermediate angular scales, with ∼15° Gaussian
spread or ∼25° top-hat radius, is obtained at the 4σ significance level for cosmic-ray energies above ∼40 EeV.},
