The Crab Nebula as a standard candle in very high-energy astrophysics

The continuum high-energy gamma-ray emission between 1 GeV and 105 GeV from the Crab Nebula has been measured for the first time in overlapping energy bands by the Fermi large-area telescope (Fermi/LAT) below  ≈100 GeV and by ground-based imaging air Cherenkov telescopes (IACTs) above  ≈60 GeV. To f...

Zusammenfassung:The continuum high-energy gamma-ray emission between 1 GeV and 105 GeV from the Crab Nebula has been measured for the first time in overlapping energy bands by the Fermi large-area telescope (Fermi/LAT) below  ≈100 GeV and by ground-based imaging air Cherenkov telescopes (IACTs) above  ≈60 GeV. To follow up on the phenomenological approach suggested by Hillas et al. (1998), the broad band spectral and spatial measurement (from radio to low-energy gamma-rays
