High Energy Astrophysics
High Energy Astrophysics concerns the study of celestial objects and phenomena that emit or absorb electromagnetic radiation at energies greater than those typically associated with optical light, i.e., above a few electron volts (eV). It encompasses various aspects of astrophysics, including cosmic rays, gamma-ray bursts, black holes, neutron stars, active galactic nuclei, and supernovae, among others. Research in this field often involves the use of space-based observatories and ground-based particle detectors, as well as theoretical modeling and simulations. High Energy Astrophysics is a dynamic and rapidly evolving field that bridges the gap between astrophysics and particle physics, offering insights into some of the most extreme environments in the universe.
