Description

Important observational results have been recently reported on the angular distributions of cosmic rays at ultra-high energies, calling into question their perception a decade ago. The extragalactic origin of the particles has been determined observationally. While no discrete source of ultrahigh-energy cosmic rays has been identified so far, the noose is tightening around nearby extragalactic objects. These results together with their in-progress interpretations are summarized in this contribution, covering both large-scale and small-scale anisotropies from sub-EeV energies to the highest ones. Some prospects are finally discussed.
