Description
The Pierre Auger Observatory, in Argentina, has been detecting for more than 15 years
ultra-high energy cosmic rays with unprecedented statistics and data quality.
Cosmic rays showers above $10^{17}$ eV are accurately measured with a large array of surface detectors covering 3000 km2 and fluorescence telescopes.
The operation of a denser sub-array with enhanced triggers has extended the sensitivity of the Surface Detector to lower energies, allowing to measure the spectrum down to 1017.0eV .
The most updated analysis concerning the spectrum, anisotropies and mass composition on more than 3 decades in energy will be presented , as well as the stringent limits on photons and neutrinos fluxes.
To enlighten these results with a more precise knowledge of the mass composition , the Auger Prime project has been designed and is currently being deployed. The scientific prospects and technical choices will be addressed.
