Indirect measurement of cosmic rays with the Pierre Auger Observatory

Cosmic rays with energies exceeding 1020 eV are the highest-energy particles in the Universe. The origin of these particles is explored with the Pierre Auger Observatory, the world largest air shower experiment.

Radio emission from air showers in the frequency range from 30 to 80 MHz is investigated with the Auger Engineering Radio Array (AERA). Air showers with energies exceeding 1017 eV are measured with 150 antennas, covering an area of 17 km2.
