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...

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. There is no evidence for the pulsar periodicity, and the flux is steady on a monthly time scale. If this signal is used to optimize the technique for gamma-ray detection, then a flux one-tenth that of the Crab can be detected at the 3 σ level in 60 hr of integration time. For an on-axis source the angular resolution is shown to be ±0°1. |
