Unique telescopes in Ondřejov observe cosmic gamma rays even during a full moon

Abstract

Two Cherenkov telescopes help us understand extreme cosmic phenomena through very high-energy gamma rays; they are currently the most sensitive devices of their kind in the world. The prototypes, which were developed by an international team involving Czech scientists, are now in Ondřejov. This is an exceptional opportunity for Czech astrophysicists, as the telescopes may be moved abroad in the future.
