Abstract.
We collected the radio, K-band, optical, X-ray, and γ-ray data for 35 TeV blazars detected by Fermi LAT and studied the possible correlation between different broad band spectral indices(α r.o, α r.x, α ir.o, α ir.x, α o.γ , α x.γ ) in all states (average/high/low). Based on our results, we suggested that the seed photons of the γ-ray drive from the synchrotron radiation themselves.
