TeV (teraelectronvolt) astronomy

TeV (teraelectronvolt) astronomy involves studying the universe using extremely high-energy particles called gamma rays, with energies trillions of times greater than visible light. These gamma rays originate from some of the most energetic and violent processes, such as supermassive black holes, supernova remnants, and neutron stars. Observing TeV gamma rays helps scientists understand extreme cosmic environments, particle acceleration mechanisms, and the fundamental physics governing the universe. Specialized telescopes detect these high-energy photons either directly or indirectly through the cascades they produce in Earth's atmosphere, allowing us to explore the universe's most energetic phenomena.
