Evolution of accretion disks around massive black holes: constraints from the demography of active galactic nuclei
Qingjuan Yu, Youjun Lu, Guinevere Kauffmann
Observations have shown that the Eddington ratios (the ratio of the bolometric luminosity to the Eddington luminosity) in QSOs/active galactic nuclei (AGNs) cover a wide range. In…
