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.

Azimuthal asymmetry in the risetime of the surface detector signals of the Pierre Auger Observatory

Billions of subatomic particles can be created in cosmic-ray induced air showers.

How airplanes were used for nanosecond-level time calibration of the Auger Engineering Radio Array

The Auger Engineering Radio Array (AERA) measures radio properties of cosmic-ray induced air showers within the Pierre Auger Observatory.

A search for cosmic-ray sources with IceCube, the Pierre Auger Observatory, and the Telescope Array

High-energy neutrinos are thought to be excellent cosmic messengers when exploring the extreme universe.
