Description
The interaction of Extragalactic Background Light (EBL) photons and gamma-rays from distant quasars results in the attenuation of the high energy tail of the gamma-ray spectrum. The attenuation depends on the EBL photon density. Clustering of galaxies on a scale of up to 100 Mpc causes fluctuations in the EBL photon density. We present an analytical model of the EBL fluctuations and discuss its effects on the hard gamma-ray spectra.
