"We are working to understand the origin of highest-energy cosmic rays with Cherenkov telescopes (MAGIC, FACT, CTA/LST), with neutrino telescopes (AMANDA, IceCube/GEN2), and with radio telescopes (MeerKAT, GLOW). To this end, cosmic messenger particles are detected and correlated in the context of multimessenger astronomy. In theoretical astrophysical and particle-physical models, we calculate the signatures expected in the telescopes. To be able to identify the signatures of these processes in our telescopes, we are working on the development of suitable simulation programs (PROPOSAL, CORSIKA).
One research focus is the development of new methods in data analysis, especially machine learning as part of artificial intelligence. Here we cooperate with computer science in the Collaborative Research Center 876 and in the Competence Center Machine Learning Rhine-Ruhr (ML2R).
We explore the epistemological understanding of this form of knowledge acquisition in cooperation with philosophy. For the experiments, we are researching various hardware aspects, also with respect to the required computer properties. This knowledge is also transferred to medical physics. Parts of the teacher training are in the responsibility of the working group."
