Abstract:
We present mass functions of distant actively accreting supermassive
black holes residing in luminous quasars discovered in the Large
Bright Quasar Survey (LBQS), the Bright Quasar Survey (BQS), and the
Fall Equatorial Stripe of the Sloan Digital Sky Survey (SDSS). The
quasars cover a wide range of redshifts from the local universe to z=5
and were subject to different selection criteria and flux density
limits. This makes these samples complementary and can help us gain
additional insight on the true underlying black hole mass distribution
free from selection effects and mass estimation errors through future
studies. We present the relationships used to estimate the black hole
mass based on the MgII emission line; the relations are calibrated to
the Hβ and CIV relations by means of several thousand
high-quality SDSS spectra. Mass estimates of the individual black
holes of these samples are also presented.
Description:
The three quasar samples for which we determine the black hole mass
functions are: the Bright Quasar Survey (BQS; Schmidt & Green
1983ApJ...269..352S 1983ApJ...269..352S; subset of Cat. II/207) using the 18 inch Palomar
Schmidt telescope with classification spectroscopy obtained with the
Hale 5m telescope. The Large Bright Quasar Survey (LBQS; e.g., Foltz
et al. 1987AJ.....94.1423F 1987AJ.....94.1423F; Hewett et al. 2001, Cat. J/AJ/122/518)
selected from the Automated Plate Measuring machine scans of the
United Kingdom Schmidt Telescope. And the color-selected sample SDSS
Fall Equatorial Stripe presented in Fan et al. (2001, Cat. J/AJ/121/31).

Note (2): Computed from the BJ survey magnitudes (Hewett et al. 2001,
Cat. J/AJ/122/518, and references therein). For cases where the
relative luminosity error exceed 1.0 the negative error of the
logarithm of the luminosity cannot be computed and this error is
instead assigned the value of the luminosity itself. In units of erg/s.
