100 years after their prediction by Albert Einstein, Gravitational Waves (GW) were detected in 2015 by the LIGO detectors.
The highest energy cosmic rays remain elusive and mysterious, and their study requires extraordinary efforts.
Maxwell’s unified description of electric and magnetic phenomena is one of the greatest achievements of 19th century physics.
Reconstruction of the muon production depth in the atmosphere with the surface detectors of the Pierre Auger Observatory
Cosmic rays are energetic particles, mostly atomic nuclei, raining down upon the Earth from the depths of the cosmos.
The energy in the radio signal of extensive air showers - a universal estimator for the cosmic-ray energy
One of the biggest challenges in cosmic-ray physics is to accurately pin down the absolute energy of a measured cosmic ray.
Billions of subatomic particles can be created in cosmic-ray induced air showers.
