Description

Unphysical distance dependence in convex features of deabsorbed blazar spectra (upward breaks), reported in 2014, suggested incorrect model of absorption of E>100 GeV gamma rays due to e+e- pair production on the extragalactic background light (EBL). We present results of the new study aimed to review previous findings, making use of an updated clean source sample, new gamma-ray data and most recent absorption models.
