Investigation of the origin of high-energy cosmic rays with direct and indirect meassurements.
Development of detecrors for Particle, Astro, and Medical Physics.
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.

Measurement of radio emission from high-energy particles with the LOFAR experiment

The LOw Frequency ARray is a large radio observatory in the Netherlands and Europe. The key science project "cosmic rays" focuses on the detectrion of radio emission induced by high-energy cosmic rays impinging the Earth's atmosphere or by high-energy particles hitting the surface of the Moon.

Measurement of high-energy gamma rays with the Cherenkov Telescope Array (CTA)

The CTA project is an initiative to build the next generation ground-based very high energy gamma-ray instrument. It will serve as an open observatory to a wide astrophysics community and will provide a deep insight into the non-thermal high-energy universe.

Measurement of radio emission in extensive air showers with the LOPES experiment

Radio emision from air showers is detected with the dipole antenna array of the LOPES experiment. The properties of the air showers are measured simultaneously with the KASCADE-Grande experiment.

Indirect measurement of cosmic rays with the air shower experiment KASCADE-Grande

Extensive air showers, induced by high-energy cosmic rays are investigated in the energy range from 1014 to 1017 eV with the experiment KASCADE-Grande. Detailed measurements of the hadronic air shower component are performed using the large hadron calorimeter.
