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.
JWST lensing data on 28 systems constrain dark matter free-streaming length to below 6-7 kpc and thermal relic mass above 6.5-7.4 keV, consistent with cold dark matter predictions.
Excessive external shear in ellipsoidal lens models of quadruply-lensed quasar NLRs always resolves position anomalies and reduces flux-ratio anomalies, concealing signals commonly attributed to dark-matter substructure.
SIDM core-collapse simulations produce a dense central core matching the lensing perturber, while CDM requires an IMBH with extreme tidal mass loss whose realism is left open.
A subhalo of M200 = 2.78e10 solar masses and concentration 30 is detected at 5.8 sigma in PJ011646 via ALMA imaging and grid-based NFW search after fitting an elliptical power-law plus multipole macromodel.
Multiwavelength analysis of 27 lensed AGN to measure bolometric luminosities and black hole masses, validating X-ray bolometric corrections with ~0.5 dex scatter and using the UV-X-ray relation to assess microlensing-induced magnification uncertainties.
