The FeII Optical Emission in AGN
C. Bongardo, R. Zamanov, P. Marziani +2
We investigated the optical FeII emission in a sample of about 215 low-redshift AGN (quasars and luminous Seyfert 1 galaxies). We find that a scaled and broadened FeII template bas…
Kinematic Linkage Between the Broad and Narrow Line Emitting Gas in AGN
R. Zamanov, P. Marziani, J. W. Sulentic +3
We investigate the radial velocity difference between the [OIII]5007,4959 and H-beta lines for a sample of 200 low redshift AGN. We identify seven objects showing an [OIII]5007 blu…
Searching for the Physical Drivers of Eigenvector-1: From Quasars to Nano-Quasars
R. Zamanov, P. Marziani
We point out an analogy between two accreting white dwarfs with jets (CH Cyg and MWC 560) and powerful quasars. In spite of the enormous difference in the mass of the central objec…
Average Quasar Spectra in the Context of Eigenvector 1
J. W. Sulentic, P. Marziani, R. Zamanov +3
[LaTeX removed] Recent work has shown that it is possible to systematize quasar spectral diversity in a parameter space called ``Eigenvector 1'' (E1). We present median AGN spectra…
