Joint Semi-Analytic Multipole Priors from Galaxy Isophotes and Constraints from Lensed Arcs
Maverick S. H. Oh, Anna Nierenberg, Daniel Gilman +1
Flux-ratio anomalies in quadruply imaged quasars are sensitive to the imprint of low-mass dark-matter haloes. The reliability of detection depends on the robustness of the smooth m…

Turbocharging constraints on dark matter substructure through a synthesis of strong lensing flux ratios and extended lensed arcs
Daniel Gilman, Simon Birrer, Anna Nierenberg +1
Strong gravitational lensing provides a purely gravitational means to infer properties of dark matter halos and thereby constrain the particle nature of dark matter. Strong lenses…

JWST Lensed quasar dark matter survey II: Strongest gravitational lensing limit on the dark matter free streaming length to date
Ryan E. Keeley, Anna M. Nierenberg, Daniel Gilman +20
This is the second in a series of papers in which we use JWST MIRI multiband imaging to measure the warm dust emission in a sample of 31 multiply imaged quasars, to be used as a pr…
