Abstract
The Pierre Auger Observatory is the largest and most important hybrid detector designed to investigate the origin and the nature of Ultra High Energy Cosmic Rays. The observatory has been continuously operated since 2004, and has achieved a total detection exposure of approximately 122000 km2sryr. During over 18 years of research, the Auger Observatory has collected a huge amount of high-quality data, which gave us knowledge about the origin of the most energetic particles ever observed in the universe. This contribution will present the main and most recent results of the arrival direction studies obtained with the Auger phase 1 dataset, i.e., the one before the installation of the upgrade Auger Prime, currently under completion. These include the searches for possible sources from small to large scale: studies of dipolar and multipolar anisotropies, the search for excesses of the order of the scale of tens of degrees at the highest energies, and the search for excesses of the order of the angular resolution (∼ 1◦) to look for neutral particles.
