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…
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…
Evidence for quasar fast outflows being accelerated at the scale of tens of parsecs
Zhicheng He, Guilin Liu, Tinggui Wang +14
Quasar outflows may play a crucial role in regulating the host galaxy, although the spatial scale of quasar outflows remain a major enigma, with their acceleration mechanism poorly…
Mutual Inclination of Ultra-Short-Period Planets with Time Varying Stellar J2-moment
Chen Chen, Gongjie Li, Cristobal Petrovich
Systems with ultra-short-period planets (USPs) tend to possess larger mutual inclinations compared to those with planets located farther from their host stars. This could be explai…
A quasar shedding its dust cocoon at redshift 2
Weimin Yi, W. N. Brandt, Q. Ni +12
We present the first near-IR spectroscopy and joint analyses of multi-wavelength observations for SDSS J082747.14+425241.1, a dust-reddened, weak broad emission-line quasar (WLQ) u…
