Blazars in Context in the Fermi Era

Abstract

Blazars are the most plentiful gamma-ray source at GeV energies, and despite detailed study, there is much that is not known about these sources. In this review I explore some recent results on blazars, including the controversy of the "blazar sequence", the curvature in the LAT spectra, and the location along the jet of the gamma-ray emitting region. I conclude with a discussion of alternative modeling possibilities.
