Recent Anisotropy Results from the Pierre Auger Observatory

ORAL

Abstract

The Pierre Auger Observatory, located in Mendoza, Argentina, is the world's largest Ultra-High Energy Cosmic Ray (UHECR) observatory and has accumulated an unprecedented exposure to UHECRs (over 100,000 km$^2$ sr yr) throughout more than fifteen years of operation. In this contribution, we report on the results from recent searches for anisotropies in the arrival directions of UHECRs. We present the observation of a large-scale dipole in arrival directions and the evolution of its phase and amplitude over more than three decades of energy. We also discuss the results from several anisotropy studies at small and intermediate scales, including correlations with candidate sources and model-independent local overdensity searches.
