Identification of gravitational lenses obscured by foreground light in the KiDS dataset using U-Nets and ResNets
S. Liu, Rui Li, J. Jia +13
*Context.* Many lensing images are often obscured by foreground light from the central galaxies, making them challenging to detect. *Aims.* To address the limitations of previous l…
Galaxy-LRD Strong Lenses: A Missing Population?
Zizhao He, Nan Li, Simon Dye +2
The physical nature of Little Red Dots (LRDs) remains uncertain, although these abundant, compact, and red sources may offer important insights into early black-hole growth and gal…
Search for Quasar Pairs with Astrometric Data. III. Discovery of 9 dual and projected quasars
Qihang Chen, Zizhao He, Zhuojun Deng +3
We report the low-resolution long-slit spectroscopic observations and confirmations of 11 quasar pair candidates, which are selected from the MGQPC catalog presented in the first p…
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…
New Dynamical Measurements from a Lensed Quasar Sample: Joint Analysis Constrains the Mass Profile Evolution of Lens Galaxies
Ziyu Guo, Yun Chen, Yiping Shu +4
We present a systematic study of the internal mass structure of early-type galaxies (ETGs) based on 106 galaxy-scale strong gravitational lenses with background quasars, all having…
Flux-ratio anomalies in cusp quasars reveal dark matter beyond CDM
Siyuan Hou, Shucheng Xiang, Yue-Lin Sming Tsai +7
Strongly lensed quasars in cusp configurations provide a uniquely sensitive probe of small-scale dark matter structure. Using the largest microlensing-free flux ratios for 17 quadr…
Searching for Galaxy Cluster-Scale Strong lenses from the DESI Legacy Imaging Surveys
Zhejian Zhang, Nan Li, Shude Mao +4
Galaxy cluster-scale strong gravitational lensing systems are rare yet valuable tools for investigating the properties of dark matter and dark energy, as well as providing the oppo…
