GEO600 Very High Frequency

GEO600 researchers will take their detector to the next level. Their goal is to search for gravitational waves at frequencies much higher than those observed by current instruments and to deepen our understanding of dark matter and the early Universe.

Technology development for gravitational-wave astronomy

GEO600 is a key technology development center of the international gravitational-wave research community. Technologies developed and tested in the GEO project are now used in all large gravitational-wave detectors in the world.
