The black hole mass versus velocity dispersion relation in QSOs/Active Galactic Nuclei: observational appearance and black hole growth
Qingjuan Yu, Youjun Lu
Studies of massive black holes (BHs) in nearby galactic centers have revealed a tight correlation between BH mass and galactic velocity dispersion. In this paper we investigate how…

Constraints on QSO models from a relation between the QSO luminosity function and the local black hole mass function
Qingjuan Yu, Youjun Lu
QSOs are believed to be powered by accretion onto massive black holes (BHs). In this paper, assuming that each central BH in nearby galaxies has experienced the QSO phase and ignor…

Testing the binary black hole paradigm through the Fe Kalpha line profile: application to 3C 273
Diego F. Torres, Gustavo E. Romero, Xavier Barcons +1
We propose the study of long-term variations in the Fe Kalpha line profile as a discriminator for binary black hole (BH) systems. The existence of a binary BH in the center of an a…
