No Evidence for a Aystematic FEII Emission Line Redshift in Type 1 AGN
J. W. Sulentic, P. Marziani, S. Zamfir +1
We test the recent claim by Hu et al. (2008) that FeII emission in Type 1 AGN shows a systematic redshift relative to the local source rest frame and broad-line Hbeta. We compile h…
Broad Line Region Physical Conditions along the Quasar Eigenvector 1 Sequence
P. Marziani, J. W. Sulentic, C. A. Negrete +3
[Abridged] We compare broad emission line profiles and estimate line ratios for all major emission lines between Ly-alpha and H-beta in a sample of six quasars. The sources were ch…
Detailed Characterization of H_beta emission line profile in low z SDSS quasars
S. Zamfir, J. W. Sulentic, P. Marziani +1
We explore the properties of the H_beta emission line profile in a large, homogeneous and bright sample of N~470 low redshift quasars extracted from Sloan Digital Sky Survey (DR5).…
Optical/UV/X-ray Insights into the RL--RQ Dichotomy
J. Sulentic, S. Zamfir, P. Marziani
We explore the relationship between radio-loud (RL) and radio-quiet (RQ) quasars using a set of optical/UV/X-ray measures that are quite independent of radio measures. We find RL s…
