Abstract / Description:The H.E.S.S. collaboration recently performed the accurate measurements of the γ-ray spectra above 200 GeV for two BL Lac-type AGN in the Southern sky: PKS 2155-304 and PKS 2005-489. The TeV spectrum of the BL Lac object 1ES 2344+514 has also been recently measured by the Whipple collaboration. Using the results of phenomenological calculations of the SED of the EBL we have extracted the intrinsic γ-ray spectra of these blazars. Consequently we have shown that these spectra can be fitted well by means of a synchrotron self Compton model.
