The Institute for Astroparticle Physics (IAP) at a Glance
Research of the Institute for Astroparticle Physics addresses fundamental puzzles of nature at the frontiers of science, where cosmology, astrophysics, and elementary particle physics meet. In collaboration with international research institutions, the IAP conducts fundamental experimental research in the fields of particle and astroparticle physics.
In large international experiments we examine the nature and origin of cosmic rays, properties of neutrinos, and the composition of dark matter.
Our projects are embedded in the programme Matter and the Universe, part of the HGF association’s research field Matter.
