At fixed galaxy stellar mass, there is a clear observational connection between structural
asymmetry and offset from the star-forming main sequence, ΔSFMS. Herein, we use the …

In the context of gravitational lensing, the density profile of lensing galaxies is often
considered to be perfectly elliptical. Potential angular structures are generally ignored …

Abstract The Wide Field Survey Telescope (WFST) is a dedicated photometric surveying
facility being built jointly by University of Science and Technology of China (USTC) and the …

We measure the correlation between black hole mass M BH and host stellar mass M* for a
sample of 38 broad-line quasars at 0.2≲ z≲ 0.8 (median redshift z med= 0.5). The black hole …

Strong gravitational lensing provides a wealth of astrophysical information on the baryonic
and dark matter content of galaxies. It also serves as a valuable cosmological probe by …

We present the discovery of a gravitationally lensed dust-reddened QSO at z= 2.517,
identified in a survey for QSOs by infrared selection. Hubble Space Telescope imaging …

We measure the host galaxy properties of five quasars with z∼ 1.6–3.5 selected from the
Sloan Digital Sky Survey (SDSS) and AEGIS, which fall within the JWST/Hubble Space …

The largest source of systematic errors in the time-delay cosmography method likely arises
from the lens model mass distribution, where an inaccurate choice of model could in …

High-redshift binary quasars provide key insights into mergers and quasar activity, and are
useful tools for probing the spatial kinematics and chemistry of galaxies along the line of …

Gravitational microlensing is a powerful tool for probing the inner structure of strongly lensed
quasars and for constraining parameters of the stellar mass function of lens galaxies. This is …
