The sizes of the broad-line regions (BLRs) in gamma-ray active galactic nuclei (AGNs) are estimated from their optical continuum luminosity by using the empirical relation between R[sub]BLR and L[sub]lambda,opt. Using broad emission line data, we derive the photon energy density in the relativistic...
