Galaxy shapes of Light (GaLight): a 2D modeling of galaxy images
Xuheng Ding, Simon Birrer, Tommaso Treu +1
Galight is a Python-based open-source package that can be used to perform two-dimensional model fitting of optical and near-infrared images to characterize the light distribution o…
Hyper Suprime-Cam Subaru Strategic Program: A Mass-Dependent Slope of the Galaxy Size-Mass Relation at
Lalitwadee Kawinwanichakij, John D. Silverman, Xuheng Ding +11
We present the galaxy size-mass () distributions using a stellar-mass complete sample of million galaxies, covering deg, with $\log(M_{\ast}…
Synchronized Co-evolution between Supermassive Black Holes and Galaxies Over the Last Seven Billion Years as Revealed by the Hyper Suprime-Cam
Junyao Li, John D. Silverman, Xuheng Ding +11
We measure the evolution of the relation using 584 uniformly-selected SDSS quasars at . The black-hole masses () are derived from the single…
Reverberation Mapping Measurements of Black Hole Masses and Broad-Line Region Kinematics in Mrk 817 and NGC 7469
Kai-Xing Lu, Jian-Guo Wang, Zhi-Xiang Zhang +7
We present the results from a spectroscopic monitoring campaign to obtain reverberation-mapping measurements and investigate the broad-line region kinematics for active galactic nu…
lenstronomy II: A gravitational lensing software ecosystem
Simon Birrer, Anowar J. Shajib, Daniel Gilman +18
lenstronomy is an Astropy-affiliated Python package for gravitational lensing simulations and analyses. lenstronomy was introduced by Birrer and Amara (2018) and is based on the li…
Optical Spectroscopy of Dual Quasar Candidates from the Subaru HSC-SSP program
Shenli Tang, John D. Silverman, Xuheng Ding +30
We report on a spectroscopic program to search for dual quasars using Subaru Hyper Suprime-Cam (HSC) images of SDSS quasars which represent an important stage during galaxy mergers…
The Sizes of Quasar Host Galaxies with the Hyper Suprime-Cam Subaru Strategic Program
Junyao Li, John D. Silverman, Xuheng Ding +11
The relationship between quasars and their host galaxies provides clues on how supermassive black holes (SMBHs) and massive galaxies are jointly assembled. To elucidate this connec…
Event rate predictions of strongly lensed gravitational waves with detector networks and more realistic templates
Lilan Yang, Shichao Wu, Kai Liao +5
Strong lensing of gravitational waves (GWs) is attracting growing attention of the community. The event rates of lensed GWs by galaxies were predicted in numerous papers, which use…
Improved time-delay lens modelling and inference with transient sources
Xuheng Ding, Kai Liao, Simon Birrer +3
Strongly lensed explosive transients such as supernovae, gamma-ray bursts, fast radio bursts, and gravitational waves are very promising tools to determine the Hubble constant ($H_…
A correction method for the telluric absorptions and application to Lijiang Observatory
Kai-Xing Lu, Zhi-Xiang Zhang, Ying-Ke Huang +7
Observing a telluric standard star for correcting the telluric absorption lines of spectrum will take a significant amount of precious telescope time, especially in the long-term s…
A local baseline of the black hole mass scaling relations for active galaxies. IV. Correlations between and host galaxy , stellar mass, and luminosity
Vardha N. Bennert, Tommaso Treu, Xuheng Ding +6
The tight correlations between the mass of supermassive black holes () and their host-galaxy properties have been of great interest to the astrophysical community, but…
