Evidence for the connection between star formation rate and evolutionary phases of quasars
Zhifu Chen, Zhicheng He, Luis C. Ho +5
Both theory and observations suggest that outflows driven by an active central supermassive black hole (SMBH) has a feedback effect on shaping the global properties of the host gal…

The detections of inflowing gas from narrow absorption lines at the parsec scale
Zhi-Fu Chen, Minfeng Gu, Zhicheng He +4
Inflows at the dusty torus and smaller scales is crucial to investigate the process of supermassive black hole accretion. However, only few cases of inflowing gas at small scales h…

The correlated variations of C IV narrow absorption lines and quasar continuum
Zhi-Fu Chen, Ting-Ting Pang, Bing He +1
We assemble 207 variable quasars from the Sloan Digital Sky Survey, all with at least 3 observations, to analyze C IV narrow absorption doublets, and obtain 328 C IV narrow absorpt…
