The low frequency of dual AGNs versus the high merger rate of galaxies: A phenomenological model
Qingjuan Yu, Youjun Lu, Roya Mohayaee +1
Dual AGNs are natural byproducts of hierarchical mergers of galaxies in the LambdaCDM cosmogony. Recent observations have shown that only a small fraction (~ 0.1%-1%) of AGNs at re…

The spatial and velocity distributions of hypervelocity stars
Fupeng Zhang, Youjun Lu, Qingjuan Yu
Hypervelocity stars (HVSs) found in the Galactic halo are probably the dynamical products of interactions between (binary) stars and the massive black hole(s) (MBH) in the Galactic…

On probing the properties of QSOs through their proximity effects on the intergalactic medium
Youjun Lu, Qingjuan Yu
The proximity effect (PE) of QSOs is believed to be useful in constraining the QSO lifetime. Observations on the PE so far, however, give apparently contradictory results -- some a…
