Highest photon energy universe
WebIn astroparticle physics, an ultra-high-energy cosmic ray ( UHECR) is a cosmic ray with an energy greater than 1 EeV (10 18 electronvolts, approximately 0.16 joules ), [1] far beyond both the rest mass and energies typical of other cosmic ray particles. WebThis minuscule amount of energy is approximately 8 × 10 −13 times the electron 's mass (via mass-energy equivalence). Very-high-energy gamma rays have photon energies of 100 GeV to over 1 PeV (10 11 to 10 15 electronvolts) or 16 nanojoules to 160 microjoules. [3] This corresponds to frequencies of 2.42 × 10 25 to 2.42 × 10 29 Hz.
