Gamma-ray observations of the Crab Nebula at TeV energies

The Crab Nebula was observed in TeV gamma rays with the Whipple Observatory high-resolution atmospheric Cherenkov camera and a signal was detected at the 20 σ level. The energy spectrum derived has the form N(E) × dE = 2.5 × 10 -10 (E/0.4 TeV) -2.4±0.3 photons cm -2 s -1 TeV -1 between 0.4 and 4 TeV...
