TeV Gamma-Ray Spectra Unfolded for IR Absorption for a Sample of Low and High Red-Shifted AGN

A. Konopelko, A. Mastichiadis, F. W. Stecker

The H.E.S.S. collaboration recently performed the accurate measurements of the gamma-ray spectra above 200 GeV for two BL Lac-type AGN in the Southern sky: PKS 2155-304 and PKS 200…
