A Method for Localizing Energy Dissipation in Blazars Using Fermi Variability

Abstract

The distance of the Fermi-detected blazar γ-ray emission site from the supermassive black hole is a matter of active debate. Here we present a method for testing if the GeV emission of powerful blazars is produced within the sub-pc scale broad line region (BLR) or farther out in the pc-scale molecular torus (MT) environment. If the GeV emission takes place… (More)
