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…
