Can third- and fourth-order multipoles plus radial variation of iso-density ellipses explain the observed flux ratios in B1422231? YES, and a lesson learned from a TNG100 lensing galaxy sample
Ruizhe Feng, Dandan Xu, Dominique Sluse +3
The paper investigates whether higher-order multipole distortions and radial variations of iso‑density ellipses, derived from TNG100 simulated galaxies, can resolve the observed im…

Why Are Some Optically Red Spirals NUV-r Blue?
Rui Guo, Cai-Na Hao, Xiaoyang Xia +2
To understand the complicated formation processes of disk galaxies, we carry out a comparative study for NUV-r blue and red spiral galaxies drawn from a parent sample of u-r red sp…
