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.
