J/ApJ/699/800     Mass functions of active black holes      (Vestergaard+, 2009)

Mass functions of the active black holes in distant quasars from the Large Bright Quasar Survey, the Bright Quasar Survey, and the color-selected sample of the SDSS Fall Equatorial Stripe. Vestergaard M., Osmer P.S. <Astrophys. J., 699, 800-816 (2009)> =2009ApJ...699..800V

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; 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; 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). File Summary:

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.
