Large-scale cosmic-ray anisotropies above 4 EeV measured by the Pierre Auger Observatory

Understand

We present a detailed study of the large-scale anisotropies of cosmic rays with energies above 4 EeV measured using the Pierre Auger Observatory.

• For the energy bins [4,8] EeV and $E\geq 8$ EeV, the most significant signal is a dipolar modulation in right ascension at energies above 8 EeV, as previously reported.
• In this paper we further scrutinize the highest-energy bin by splitting it into three energy ranges.
• We find that the amplitude of the dipole increases with energy above 4 EeV.
