ultra-high-energy gamma rays
(UHEGR)
(energetic gamma rays with more than 100 TeV photon energy)
The term ultra-high-energy gamma rays (UHEGR) is used for gamma rays
with more than 100 TeV photon energy. This energy span is
next after that of very-high-energy gamma rays (VHEGR) (100 GeV to 100 TeV). Observed UHEGR
photons were first announced in 2019, from the Crab Nebula.
Note that prefix UHE is also used for cosmic rays but with
a "minimum energy threshold" that is higher.
