Measuring Outflow Distances in NGC 5548 Using Absorption-Line Variability Diagnostics

Yaqi Chen, Zhicheng He, Guilin Liu

AGN-driven outflows serve as a key channel through which the energetic central engine influences host galaxy evolution. Among the physical properties of outflows, their radial dist…

Galactic-scale emission-line outflow from the radio-loud quasar 3C 191

Qinyuan Zhao, Luming Sun, Lu Shen +6

Quasar feedback is routinely invoked as an indispensable ingredient in galaxy formation models. Galactic outflows are a crucial agent of quasar feedback that frequently manifest th…
