How many radio-loud quasars can be detected by the gamma-ray large area space telescope?

, 2008
In the unification scheme, radio quasars and FR II radio galaxies come from the same parent population, but viewed at different angles. Based on the Comptonization models for the gamma-ray emission from active galactic nuclei (AGNs), we estimate the ...
