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.
