Astroparticle physics is a field of astrophysics with the goal of understanding the universe using particle physics methods. To this end, we measure high-energy particle beams from the universe. Some of the observatories are located in remote places, such as the South Pole or the Argentine steppe.
The research program of the working groups is interdisciplinary: It includes data analysis and development of new detection methods, accelerator experiments to study the states in the early universe and the interior of neutron stars, the measurement of the mass of neutrinos, as well as space programs to search for extraterrestrial life.
