Radial gradients revealed by mutliscale outflows from down-the-barrel spectroscopy toward a quasar at redshift 3.4
Weimin Yi, Paola Rodriguez Hidalgo, Chen Chen +9
Active galactic nucleus(AGN) feedback is a key ingredient in galaxy formation models and simulations. From an observational point of view, however, the channels of AGN feedback cou…
Symmetry in Fundamental Parameters of Galaxies on the Star-forming Main Sequence
Zhicheng He, Enci Wang, Luis C. Ho +4
The Star-Forming Main Sequence (SFMS) serves as a critical framework for understanding galaxy evolution, highlighting the relationship between star formation rates (SFR) and stella…
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…
Tracking Outflow using Line-Locking (TOLL). II. Large Line-Locking Web identified in Quasar J151352+085555
Chen Chen, Zhicheng He, Weimin Yi +3
Quasar outflows often consist of two clouds with velocity separations matching the doublet spacings of common UV resonance transitions, a phenomenon known as line-locking, which is…
Tracking Outflow using Line-Locking (TOLL). I. The case study of Quasar J221531-174408
Chen Chen, Weimin Yi, Zhicheng He +2
Investigating line-locked phenomena within quasars is crucial for understanding the dynamics of quasar outflows, the role of radiation pressure in astrophysical flows, and the star…
