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…
Constraining the Physical Properties of Quadruply Lensed Quasars using Optical-to-X-Ray Data
Kriti Kamal Gupta, Dominique Sluse, Maarten Baes +5
Gravitational lensing of luminous active galactic nuclei (AGN; or quasars) can be used as a natural telescope to zoom in on their inner structures. With more and more lensed AGN be…
JWST lensed quasar dark matter survey IV: Stringent warm dark matter constraints from the joint reconstruction of extended lensed arcs and quasar flux ratios
D. Gilman, A. M. Nierenberg, T. Treu +23
We present a measurement of the free-streaming length of dark matter (DM) and subhalo abundance around 28 quadruple image strong lenses using observations from JWST MIRI presented…
The free-streaming length of dark matter from JWST observations of 28 strong gravitational lenses
D. Gilman, A. M. Nierenberg, T. Treu +24
The formation of gravitationally bound overdensities of dark matter (DM), or \textit{halos}, is a generic prediction of theories with particle DM. We present a measurement of halo…
TDCOSMO XXVI: Uniform lens modeling of eight doubly imaged quasars
Ryan Brady, Xiang-Yu Huang, Simon Birrer +7
We present the first uniform gravitational lens modeling analysis of eight doubly imaged quasars from multi-band observations with the Hubble Space Telescope. Previous time-delay c…
Euclid Quick Data Release (Q1). AstroVink: A vision transformer approach to find strong gravitational lens systems
Euclid Collaboration, S. H. Vincken, K. Rojas +302
We present AstroVink, a vision transformer classifier designed for automated identification of strong lens candidates in Euclid imaging. We build upon the DINOv2 encoder, fine tune…
