We construct a simple elliptical gravitational lens model for the quadruple lens B1422+231 and show that the details of the configuration cannot be easily understood in terms of this model; in particular, the flux ratios of the images are hard to reproduce. This qualitatively verifies the results from a different lens model constructed for the same object by Hogg and Blandford.

  1. First measurement of narrow-line flux ratios for a lensed quasar with JWST/NIRSpec IFS

    astro-ph.GA 2026-06 unverdicted novelty 7.0 of 10

    First narrow-line flux ratios for lensed quasar RXJ1131-1231 measured with JWST/NIRSpec IFS at ~5% precision, detecting cusp anomaly consistent with prior work.

  2. Can third- and fourth-order multipoles plus radial variation of iso-density ellipses explain the observed flux ratios in B1422$+$231? YES, and a lesson learned from a TNG100 lensing galaxy sample

    astro-ph.GA 2026-07 conditional novelty 6.0 of 10

    Third- and fourth-order multipoles plus radial iso-density variations extracted from TNG100 can fully explain B1422+231 positions and flux ratios under realistic uncertainties, without clumpy substructure.

  3. Across the Universe: GW231123 as a magnified and diffracted black hole merger

    astro-ph.GA 2025-12 conditional novelty 6.0 of 10

    GW231123's extreme mass and spins may be explained by a point-mass microlens embedded in a galaxy, reducing the inferred source mass to about 100-180 solar masses.

  4. Varstrometry for Off-nucleus and Dual Subkiloparsec AGN (VODKA): Three Quadruply Lensed Quasars at Cosmic Noon in HST and JWST

    astro-ph.GA 2026-02 conditional novelty 5.0 of 10

    Three quadruply lensed quasars at z≈1.5–3.0 have lens galaxies with Einstein radii 0.44–0.58 arcsec and photometrically constrained redshifts 0.4–1.5, placing them among the smallest-separation, highest-redshift galax...
