Abstract: We spectrally fit the GeV gamma-ray flares that have recently been observed in the Crab nebula by considering a small blob Lorentz-boosted towards us. We point out that the corresponding inverse Compton flare at the TeV–PeV region is more enhanced than synchrotron emission by a Lorentz factor squared (∼Γ2). This already excludes and it will be detected by future TeV–PeV observatories, such as the Cherenkov Telescope Array (CTA), the Tibet Air Shower plus Muon Detector (Tibet AS+MD) array and the Large High Altitude Air Shower Observatory (LHAASO), for . We also show that PeV photons emitted from the Crab nebula are absorbed by cosmic microwave background radiation through electron–positron pair creation.
