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…
Dissecting the multiple-component outflow in NGC 5548 with absorption-line Variability
Yaqi Chen, Zhicheng He, Guilin Liu
AGN-driven outflows are routinely invoked as a key agent of supermassive black holes to regulate the evolution of galaxies. The radial distance from the central engine is a crucial…
ELFO: A Python Package for Emission Line Fitting Optimization in Integral Field Spectroscopy Data
Hui Guo, Guilin Liu, Jianghui Xu +4
Integral field spectroscopy (IFS) provides spatially resolved spectra, enabling detailed studies that address the physical and kinematic properties of the interstellar medium. A cr…
The distance of quasar outflows from the central source: The first consistent values from emission and absorption determinations
Mayank Sharma, Nahum Arav, Qinyuan Zhao +8
Measuring the distance of quasar outflows from the central source () is essential for determining their importance for AGN feedback. There are two methods to measure : 1) A d…
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…
