The Broad Line Region of Quasars
P. Marziani, J. W. Sulentic, D. Dultzin
The last decade saw long-awaited improvements in our understanding of active galactic nuclei (AGN) spectral properties. This contribution reviews some important observational resul…
Our Search for an H-R Diagram of Quasars
Jack W. Sulentic, Sebastian Zamfir, Paola Marziani +1
The 4D Eigenvector 1 parameter space was introduced seven years ago as an attempt at multiwavelength spectroscopic representation of quasars. It appears to be the most effective di…
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…
