New Insights on the QSO Radio-Loud/Radio-Quiet Dichotomy: SDSS Spectra in the Context of the 4D Eigenvector1 Parameter Space
Sebastian Zamfir, Jack W. Sulentic, Paola Marziani
We search fora dichotomy/bimodality between Radio Loud (RL) and Radio Quiet (RQ) Type 1 Active Galactic Nuclei (AGN). We examine several samples of SDSS QSOs with high S/N optical…
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…
Radio Loud AGN in the Context of the Eigenvector 1 Parameter Space
J. W. Sulentic, S. Zamfir, P. Marziani +3
We consider the properties of radio-loud (RL) AGN in the context of the Eigenvector 1 (E1) parameter space. RL sources show a restricted E1 parameter space occupation relative to t…
