high-energy astrophysics

(HEA, high-energy astronomy)
(astronomy and physics of X-rays and gamma rays)

The terms high-energy astrophysics and high-energy astronomy (HEA) are used for observation and physical modeling in the shorter-wavelength EMR bands, extreme ultraviolet, X-rays, and gamma rays, as well as cosmic rays and neutrinos. The term may also be used for the study of very energetic events and processes such as supernova, active galactic nuclei/quasars, gamma-ray bursts, which are often associated with such high energy photons.
