2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/9437The 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 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 gamma-ray spectra of these blazars. Consequently we have shown that these spectra can be fitted well by means of a synchrotron self Compton model.4 pages, 1 figure, Proc. of 29th ICRC, Pune, India, 2005Astrophysicstext
