Revealing the Physical Driver of the Baldwin Effect: Gas Density in the Broad-Line Region
Wen-Qiang Liang, Zhi-Fu Chen, Rui-Jing Lu +8
The paper shows that the Baldwin effect in quasars is mainly driven by the gas density in the broad-line region, with higher Eddington ratios producing denser BLRs and shallower eq…

The infrared traced star formation rates of associated absorption lines quasars
Zhe-Geng Chen, Rui-Jing Lu, Zhi-Fu Chen +4
Some optically selected quasars exhibit Mg II assoicated absorption lines (AALs), and its origin remains unclear. In this paper, we compile a sample of 1769 quasars, with or withou…
