Pierre Auger Observatory


The Pierre Auger Observatory is studying ultra-high energy cosmic rays the most energetic particles in the Universe. When such a rare particle strikes the Earths atmosphere, it produces an extensive air shower (EAS) made of billions of particles. While cosmic rays with low to moderate energies are well understood, those with extremely high energies remain mysterious. The hybrid nature of the Pierre Auger Observatory provides two independent ways to see cosmic rays. These two ways are an array of 1600 (water-filled) surface detectors and 24 air-fluorescence telescopes, located in four different buildings.

Researchers from the KVI work together with other groups in the Netherlands (ASTRON, IMAPP of the RU, and NIKHEF) in Europe and the USA on the development of a new detection technique for cosmic rays: observation of cosmic rays using radio receivers.
