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…

Ejection of hypervelocity stars by the (binary) black hole(s) in the Galactic center
Qingjuan Yu, Scott Tremaine
We study three processes that eject hypervelocity (>10^3 km/s) stars from the Galactic center: (i) close encounters of two single stars; (ii) tidal breakup of binary stars by the c…
