The emission of blazars in very-high-energy gamma-rays viewed as a random stationary process : the case of PKS 2155-304

With the advent of the new generation of Cherenkov telescope s such as H.E.S.S., MAGIC, CANGAROO III and VERITAS, about 20 active galactic nuclei belon ging to the blazar category have been clearly detected at very high energies. Spectacular fla res were observed in a few of them, such as Mkn 421, Mkn 501 and PKS 2155-304, during which gammaray fluxes could… (More)
