Testing hadronic interaction models using hybrid data of the Pierre Auger Observatory
An unusual collaboration leads to spectacular results.
This is still an open question in astroparticle physics and a long-standing mystery that the Pierre Auger Observatory aims to solve.
Understanding the origin and nature of ultra-high energy cosmic rays has been one of the driving forces of the field of astroparticle physics. A key piece of information is what type of particles cosmic rays consist of.
For the first time, the possible appearance of ultra-high energy photons from merging compact objects such as black holes was tested.
