J/other/ChA+A/32.351        Accretion rate distributions of AGNs    (Bao+, 2008)

A study of the black hole mass and accretion rate distributions of AGNs. Bao Y.-Y., Zhang X., Chen L.-E., Zhang H.-J., Peng Z.-Y., Zheng Y.-G. <Chinese Astron., 32, 351-359 (2008)> =2008ChA&A..32..351B
ADC_Keywords: Active gal. nuclei ; QSOs ; Redshifts Keywords: quasars: general - galaxy: Seyfert - galaxy: black hole - galaxy: distance and redshift Abstract: The redshift, central black hole mass and accretion rate are important parameters when studying the AGN evolution. The central black hole masses for 172 quasars and Seyfert galaxies are calculated in this paper using the reverberation mapping method. The distributions of central black hole masses, redshifts and the Eddington accretion rates are analyzed, to verify the transition from the quasar to the Seyfert galaxy in the course of evolution.
