Mock Observations for the CSST Mission: Main Surveys -- the Mock Catalogue
Cheng-Liang Wei, Yu Luo, Hao Tian +17
The Chinese Space Station Survey Telescope (CSST) is a flagship space mission, designed to carry out a large-area sky survey to explore the nature of dark matter and dark energy in…
CURLING -- II. Improvement on the Inference from Pixelized Cluster Strong Lens Modeling
Yushan Xie, Huanyuan Shan, Yiping Shu +9
Strongly lensed supernovae (glSNe) provide a powerful, independent method to measure the Hubble constant, , through time delays between their multiple images. The accuracy o…
CURLING -- III. Identifying Candidates of Wide-separation Gravitationally Lensed Quasars from the CatNorth Catalogue
Di Wu, Zizhao He, Nan Li +5
Wide-separation lensed quasars (WSLQs) are a rare subclass of strongly lensed quasars produced by massive galaxy clusters. They provide valuable probes of dark-matter halos and qua…
Confirming lensed-quasar candidates with DESI and P200 spectroscopy I. 14 lensed quasars and 8 lensed galaxies
Zizhao He, Qihang Chen, Xiaosheng Huang +3
Lensed quasars are powerful probes of cosmology, the co-evolution of supermassive black holes and their host galaxies, and the distribution of dark matter. We cross-match 1,724 pre…
GalaxyGenius: Mock galaxy image generator for various telescopes from hydrodynamical simulations
Xingchen Zhou, Hang Yang, Nan Li +11
We introduce GalaxyGenius, a Python package designed to produce synthetic galaxy images tailored to different telescopes based on hydrodynamical simulations. Its implementation wil…
Discovery of a Low-mass Strong-lens System in SMACS J0723.3-7327
Limeng Deng, Yiping Shu, Lei Wang +6
We report the discovery of an intriguing, low-mass galaxy-scale strong-lens system in the SMACS J0723.3-7327 galaxy cluster. By modeling James Webb Space Telescope imaging and Very…
Search for Quasar Pairs with Astrometric Data. I. Method and Candidates
Qihang Chen, Liang Jing, Xingyu Zhu +5
Quasar pairs, a special subclass of galaxy pairs, are valuable in the investigation of quasar interaction, clustering, co-evolution between the two quasars' host galaxies, the grow…
Discovery of 19 strongly-lensed quasars, dual and projected quasars in DESI-LS
Zizhao He, Qihang Chen, Limeng Deng +5
We report the follow-up spectroscopic confirmation of two lensed quasars, six dual quasars, and eleven projected quasars that were previously identified as lensed-quasar candidates…
Forecast of gravitationally lensed Type Ia supernovae time delay measurement by Muztage-Ata 1.93m Synergy Telescope
Guanhua Rui, Wenwen Zheng, Zizhao He +4
Strong lensing time delay measurement is a promising method to address the Hubble tension, offering a completely independent approach compared to both the cosmic microwave backgrou…
