Discovery of a radiation component from the Vela pulsar reaching 20 teraelectronvolts - Nature Astronomy
The H.E.S.S. gamma-ray observatory has observed gamma rays with energies of at least 20 TeV from a pulsar, an energy regime that is hard to reconcile with the existing theories of gamma-ray production for such objects.
