In-situ star formation in accretion disk and explanation for correlation between black hole mass and metallicity in AGNs
Xiao Fan, Qingwen Wu
Recent observations show that the metallicity of the broad line region () in active galactic nuclei (AGNs) is solar-to-supersolar, which is positively correlated with…
Accretion-modified stellar-mass black hole distribution and milli-Hz gravitational wave backgrounds from galaxy centre
Mengye Wang, Yiqiu Ma, Qingwen Wu
Gas accretion of embedded stellar-mass black holes\,(sBHs) or stars in the accretion disk of active galactic nuclei\,(AGNs) will modify the mass distribution of these sBHs and star…
A model for the possible connection between tidal disruption event and quasi-periodic eruption in GSN 069
Mengye Wang, Jinjing Yin, Yiqiu Ma +1
Quasi-periodic eruptions (QPEs) are found in the center of five galaxies, where a tidal disruption event (TDE)-like event is also reported in GSN 069 that happened a couple of year…
Coevolution of broad emission lines and X-ray spectrum in changing-look AGNs
Hao Liu, Qingwen Wu, Bing Lyu
Changing-look active galactic nuclei (CLAGNs) show the disappearance and reappearance of broad emission lines in a few years, which challenges the orientation-based AGN unification…
Evidence for quasar fast outflows being accelerated at the scale of tens of parsecs
Zhicheng He, Guilin Liu, Tinggui Wang +14
Quasar outflows may play a crucial role in regulating the host galaxy, although the spatial scale of quasar outflows remain a major enigma, with their acceleration mechanism poorly…
