Constraints on the origin of cosmic rays above 10(18) eV from large-scale anisotropy searches in data of the pierre auger observatory.

A thorough search for large-scale anisotropies in the distribution of arrival directions of cosmic rays detected above 10(18) eV at the Pierre Auger Observatory is reported. For the first time, these large-scale anisotropy searches are performed as a function of both the right ascension and the decl...
