Neural posterior estimation of the line-of-sight and subhalo populations in galaxy-scale strong lensing systems
Birendra Dhanasingham, Francis-Yan Cyr-Racine, Daniel Gilman
Strong gravitational lensing is a powerful probe for studying the fundamental properties of dark matter on sub-galactic scales. Detailed analyses of galaxy-scale lenses have reveal…
JWST Lensed Quasar Dark Matter Survey III: Dark Matter Sensitive Flux Ratios and Warm Dark Matter Constraint from the Full Sample
R. E. Keeley, A. M. Nierenberg, D. Gilman +24
We present the full sample of measurements of the warm dust emission of 31 strongly-lensed, multiply imaged quasars, observed with JWST MIRI multiband imaging, which we use to cons…
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…
Dents in the Mirror: A Novel Probe of Dark Matter Substructure in Galaxy Clusters from the Astrometric Asymmetry of Lensed Arcs
Derek Perera, Daniel Gilman, Liliya L. R. Williams +5
Astrometric perturbations of lensed arcs behind galaxy clusters have been recently suggested as promising probes of small-scale () dark matter substructure.…
Macromodel-free flux-ratio prediction in quadruply imaged quasars with local constraints from lensed arcs
Hadrien Paugnat, Tommaso Treu, Daniel Gilman
Strong gravitational lensing is a powerful cosmological probe, providing a direct tool to unveil the properties of dark matter (DM) on sub-galactic scales. In particular, flux-rati…
TDCOSMO 2025: Cosmological constraints from strong lensing time delays
TDCOSMO Collaboration, Simon Birrer, Elizabeth J. Buckley-Geer +30
We present cosmological constraints from 8 strongly lensed quasars (hereafter, the TDCOSMO-2025 sample). Building on previous work, our analysis incorporated new deflector stellar…
