AGN Emission Lines
From Netzer et al. 1994 (I did the figures), on the SED and unusual emission line profiles of the OVV 3C 279.  Note the steep power-law spectrum.  Optically polarization is high.  There is optical beamed synchrotron radiation in this source.
In many quasars, the emission line profiles are similar from line to line (consistent with optically thick BLR clouds).  Not so for all objects, and especially important for figuring out BLR kinematics and dynamics (which is still not so clear).
