J/ApJ/666/757       CIV 1549Å emission line in AGNs       (Sulentic+, 2007)

C IV λ1549 as an Eigenvector 1 parameter for active galactic nuclei. Sulentic J.W., Bachev R., Marziani P., Negrete C.A., Dultzin D. <Astrophys. J., 666, 757-777 (2007)> =2007ApJ...666..757S
ADC_Keywords: QSOs ; Active gal. nuclei ; Line Profiles Keywords: line: profiles - quasars: emission lines - quasars: general Abstract: We are exploring a spectroscopic unification for all types of broad-line emitting AGNs. The four-dimensional Eigenvector 1 (4DE1) parameter space organizes quasar diversity in a sequence primarily governed by Eddington ratio. This paper considers the role of CIV λ1549 measures as 4DE1 diagnostics. We use HST archival spectra for 130 sources with S/N high enough to permit reliable CIV λ1549 broad-component measures.

Note (1): In units of 1e-14 erg/s/cm2/Angstroms. Note (2): In units of 1e-13 erg/s/cm2. Note (3): Flag on FCIVNC as follows: A = major absorptions (typically of mini-BALs) affecting the profile of CIV (150nm) broad component a = narrow absorptions that "eat away" CIV (150nm) narrow component but that do not hamper CIV (150nm) broad component measurements Note (4): If "E_Kurt" isn't blank then "e_Kurt" is the lower uncertainty.
