The High-Energy Astrophysics Group (GAPHE)

The most violent and/or spectacular phenomena in the cosmos can often be seen at high energies. This part of the electromagnetic spectrum offers a unique view on our Universe: galaxy collisions, accretions by black holes or neutron stars, supernovae, hydrodynamical shocks - all these phenomena are conspicuous in X-rays or gamma-rays. The atmosphere of our planet, however, blocks these rays so that their observation can only be performed from space-based observatories.

The High-Energy Astrophysics Group (GAPHE) of the Institute of Astrophysics and Geophysics uses these satellites to study massive stars and their interactions with their environment. These studies are complemented by observations in the visible and infrared domains using ground-based and space-based telescopes.

These pages will enable you to know more about our work, also through outreach pages, our team, and the TIGRE project.
