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…
Balmer line shifts in quasars
J. W. Sulentic, P. Marziani, A. Del Olmo +1
We offer a broad review of Balmer line phenomenology in type 1 active galactic nuclei, briefly sum- marising luminosity and radio loudness effects, and discussing interpretation in…
3C 57 as an Atypical Radio-Loud Quasar: Implications for the Radio-Loud/Radio-Quiet Dichotomy
J. W. Sulentic, M. A. Martínez-Carballo, P. Marziani +4
Lobe-dominated radio-loud (LD RL) quasars occupy a restricted domain in the 4D Eigenvector 1 (4DE1) parameter space which implies restricted geometry/physics/kinematics for this su…
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).…
