What does CIV λ1549 tell us about the physical driver of the Eigenvector quasar sequence?

ADC_Keywords: QSOs ; Atlases ; Spectrophotometry Keywords: quasars: general - quasars: emission lines - quasars: supermassive black holes Abstract: Broad emission lines in quasars enable us to "resolve" structure and kinematics of the broad-line emitting region (BLR) thought to involve an accretion disk feeding a supermassive black hole. Interpretation of broad line measures within the 4DE1 formalism simplifies the apparent confusion among such data by contrasting and unifying properties of so-called high and low accreting Population A and B sources. H-beta serves as an estimator of black hole mass, Eddington ratio and source rest frame; the latter being a valuable input for CIV 1549 studies which allow us to isolate the blueshifted wind component. Optical and HST-UV spectra yield H-beta and CIV 1549 spectra for low-luminosity sources while VLT-ISAAC and FORS and TNG-LRS provide spectra for high-luminosity sources. New high-S/N data for CIV in high-luminosity quasars are presented here for comparison with the other previously published data. Comparison of H-beta and CIV 1549 profile widths/shifts indicates that much of the emission from the two lines arise in regions with different structure and kinematics. Covering a wide range of luminosity and redshift shows evidence for a correlation between CIV 1549 blueshift and source Eddington ratio, with a weaker trend with source luminosity (similar amplitude outflows are seen over four of the five dex luminosity ranges in our combined samples). At low luminosity (z<0.7) only Population A sources show evidence for a significant outflow while at high luminosity the outflow signature begins to appear in Population B quasars as well. Description: Spectroscopic data for 28 intermediate redshift quasars are identified in Table 1. Actual data files are in FITS format in the spectra sub-directory. Units are in wavelength in Angstroms, and specific flux in erg/s/cm2/Angstrom (pW/m3)x1E15 in the rest frame (i.e., after redshift correction). The last column of Table 1 reports the FITS file names.
