Modeling the hard TeV spectra of blazars 1ES0229+200 and 3C66A with an internal absorption scenario

Abstract

We study the applicability of the idea of internal absorption of γ-rays produced through synchrotron radiation of ultrarelativistic protons in highly magnetized blobs to 1ES0229+200 and 3C66A, the two TeV blazars which show unusually hard intrinsic γ-ray spectra after being corrected for the intergalactic absorption. We show that for certain combinations of reasonable model parameters, even with quite modest energy requirements, the scenario allows a self-consistent explanation of the non-thermal emission of these objects in thekeV,GeV, andTeV energy bands. © 2011.
