HighEnergy Astrophysics
High-energy astrophysics is the branch of astronomy that focuses on studying the most energetic phenomena in the universe. This includes the study of cosmic rays, gamma-ray bursts, supernovae, active galactic nuclei, and black holes. High-energy astrophysicists use a combination of theoretical models, computer simulations, and observations from ground-based and space-based telescopes to understand the extreme conditions and processes that occur in these high-energy environments.
