Discovery of a Strong-lens Galaxy Pair with the Smallest Projected Separation
Zizhao He, Limeng Deng, Qihang Chen +3
We present the spectroscopic confirmation and lens modeling of HSC~J02330205, a strong-lensing system produced by a close pair of elliptical galaxies at that…
Group Pre-processing in J1611+4026: Minor Rejuvenation of a Massive ETG fueled by Interaction-driven Gas Transfer
Yaosong Yu, Qihang Chen, Zizhao He +3
Interactions within galaxy groups are fundamental drivers of galactic evolution, and establishing a direct observational link between the dynamical processes of satellite galaxies…
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…
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…
Using Convolutional Neural Networks to Search for Strongly Lensed Quasars in KiDS DR5
Zizhao He, Rui Li, Yiping Shu +13
Gravitationally strongly lensed quasars (SL-QSO) offer invaluable insights into cosmological and astrophysical phenomena. With the data from ongoing and next-generation surveys, th…
