Abstract

The detection of bright, variable γ-ray emission from about 40 blazars by the EGRET instrument on CGRO and the nondetection of radio quite AGN or extended radio sources, has lent additional support to the unified model of AGN. It is now widely believed that the γ-ray emission seen originates from a relativistic jet pointing along our line of sight, and several models involving X-and γ-ray production in jets have been proposed recently. Below we consider a specific class of models involving pair-cascade processes, and discuss some of the observational consequences of these models.
