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).
