 abstract={Ultra-high-energy gamma rays are stopped by the Earth’s atmosphere before they can reach the planet’s surface. However, our atmosphere could also become a tool for detecting photons with energies in the teraelectronvolt range. By using instruments registering Cherenkov radiation, astronomers conduct observations of sources emitting ultra-high-energy photons with ground-based telescopes.},
