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…
A Unified Halo Mass Function Across Dark Matter Models from High-Resolution Multi-Scale Simulations
Andrew J. Benson, Ethan O. Nadler, Xiaolong Du +1
We measure the dark matter halo mass function, with backsplash halos removed, from a wide range of cosmological-box and zoom-in simulations. These include the MultiDark Planck boxe…
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…
The Sensitivity of Substructure Lensing to SIDM Core-collapse Model Variation
Charlie Mace, Birendra Dhanasingham, Zhichao Carton Zeng +4
Strong gravitational lensing has emerged as a powerful probe of dark matter substructure, and shows particularly strong promise as a test of self-interacting dark matter (SIDM). Th…
Measurement of the minimum cold dark matter halo mass with strong gravitational lensing
A. M. Nierenberg, D. Gilman, T. Treu +19
We explore the lowest mass limit that can be placed on the halo mass function in CDM using 28 strong gravitational lenses. For this purpose, we study an extreme model in which the…
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…
