VLT/ISAAC Spectra of the Hbeta Region in Intermediate-Redshift Quasars III. Hbeta Broad Line Profile Analysis and Inferences about BLR Structure
P. Marziani, J. W. Sulentic, G. M. Stirpe +2
[Abridged] We present new VLT ISAAC spectra for 30 quasars, which we combine with previous data to yield a sample of 53 intermediate redshift (z ~ 0.9 - 3.0) sources. The sample is…
SDSS J1130+0058 an X-shaped Radio Source With Double-Peaked Low-Ionization Emission Lines: A binary Black Hole System?
Xue-Guang Zhang, Dultzin-Hacyan D., Ting-Gui Wang
In this paper we study the object SDSS J1130+0058 which is the only AGN known to have both double-peaked low-ionization broad emission lines, and also X-shaped radio structures. Em…
VLT/ISAAC Spectra of the H-beta Region in Intermediate-Redshift Quasars II. Black Hole Mass and Eddington Ratio
J. W. Sulentic, P. Repetto, G. M. Stirpe +3
We derive black hole masses for a sample of about 300 AGNs in the redshift range 0 < z < 2.5. We use the same virial velocity measure (FWHM Hbeta broad component) for all sources w…
Low Redshift BAL QSOs in the Eigenvector 1 Context
J. W. Sulentic, D. Dultzin-Hacyan, P. Marziani +4
We attempt to characterize the geometry of Broad Absorption Line (BAL) QSOs by studying a low redshift sample of 12 sources. We find that the majority of these sources are Populati…
Local and Large scale Environment of Seyfert Galaxies
E. Koulouridis, M. Plionis, V. Chavushyan +3
We present a three-dimensional study of the local (<100 h^-1} kpc) and the large scale (<1 h^{-1} Mpc) environment of the two main types of Seyfert AGN galaxies. For this purpose w…
Average UV Quasar Spectra in the Context of Eigenvector 1: A Baldwin Effect Governed by Eddington Ratio?
R. Bachev, P. Marziani, J. W. Sulentic +3
We present composite UV spectra for low redshift Type 1 AGN binned to exploit the information content of the Eigenvector 1 (E1) parameter space. Composite spectra allow a decomposi…
