Black hole mass estimates in quasars - A comparative analysis of high- and low-ionization lines
P. Marziani, A. del Olmo, M. A. Martinez-Carballo +7
The inter-line comparison between high- and low-ionization emission lines has yielded a wealth of information on the quasar broad line region (BLR) structure and dynamics, includin…
HE0359-3959: an extremely radiating quasar
M. L. Martínez-Aldama, A. Del Olmo, P. Marziani +3
We present a multiwavelength spectral study of the quasar HE0359-3959, which has been identified as an extreme radiating source at intermediate redshift (z=1.5209). Along the spect…
A possible binary AGN in Mrk\,622?
E. Benítez, J. M. Rodríguez-Espinosa, I. Cruz-González +5
Mrk\,622 is a Compton Thick AGN and a double-peaked narrow emission line galaxy, thus a dual AGN candidate. In this work, new optical long-slit spectroscopic observations clearly s…
Quasar massive ionized outflows traced by CIV λ1549 and [OIII]λλ4959,5007
P. Marziani, C. A. Negrete, D. Dultzin +4
The most luminous quasars (with bolometric luminosities are 1E47 erg/s) show a high prevalence of CIV λ1549 and [OIII]λλ4959,5007 emission line profiles with strong blueshifts. Blu…
What does Civλ1549 tell us about the physical driver of the Eigenvector Quasar Sequence?
J. W. Sulentic, A. del Olmo, P. Marziani +8
Broad emission lines in quasars enable us to "resolve" structure and kinematics of the broad line emitting region (BLR) thought to in- volve an accretion disk feeding a supermassiv…
CIV 1549 as an Eigenvector 1 Parameter for Active Galactic Nuclei
Jack W. Sulentic, Rumen Bachev, Paola Marziani +2
[Abridged] We have been exploring a spectroscopic unification for all known types of broad line emitting AGN. The 4D Eigenvector 1 (4DE1) parameter space shows promise as a unifica…
