More than half a century after the discovery of ultra-high energy cosmic rays (UHECRs), their
origin is still an open question. The study of anisotropies in the arrival directions of such …

We report a multi-resolution search for anisotropies in the arrival directions of cosmic rays
detected at the Pierre Auger Observatory with local zenith angles up to 80◦ and energies in …

The large-scale distribution of arrival directions of cosmic rays is an important observable in
attempts to understand their origin. This is because this observable is closely connected to …

Searches for large-scale anisotropies in the distribution of arrival directions of cosmic rays
detected above≊ 10 PeV at the Pierre Auger Observatory are presented. Although no …

Spherical harmonic moments are well-suited for capturing anisotropy at any scale in the flux
of cosmic rays. An unambiguous measurement of the full set of spherical harmonic …

Abstract Recently, the High Resolution Fly's Eye (HiRes) experiment has indicated that there
is no small-scale anisotropy in the arrival distribution of ultra-high-energy cosmic rays …

The distribution of the arrival directions of cosmic rays, together with the spectrum and
composition indicators, are the main observables to try to understand their origin and nature …
