JWST lensed quasar dark matter survey V: Hints of self-interacting dark matter from 29 quadruply imaged quasars

D. Gilman, A. M. Nierenberg, J. Gurian +21

Theories of self-interacting dark matter (SIDM) predict the eventual core collapse of dark matter halos, a process that transforms these structures into extremely efficient gravita…

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…

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…

Generating Dark Matter Subhalo Populations Using Normalizing Flows

Jack Lonergan, Andrew Benson, Daniel Gilman

Strong gravitational lensing is a powerful tool for probing the nature of dark matter, as lensing signals are sensitive to the dark matter substructure within the lensing galaxy. W…

Faster than SAM: An empirical model for the tidal evolution of dark matter substructure around strong gravitational lenses

Xiaolong Du, Daniel Gilman, Tommaso Treu +2

Strong gravitational lenses enable direct inference of halo abundance and internal structure, which in turn enable constraints on the nature of dark matter and the primordial matte…

Dark Galactic subhalos and the Gaia snail

Daniel Gilman, Jo Bovy, Neige Frankel +1

Gaia has revealed a clear signal of disequilibrium in the solar neighborhood in the form of a spiral (or snail) feature in the vertical phase-space distribution. We investigate the…

Dark Matter Substructure: A Lensing Perspective

Charles Gannon, Anna Nierenberg, Andrew Benson +3

The study of dark matter substructure through strong gravitational lensing has shown enormous promise in probing the properties of dark matter on sub-galactic scales. This approach…

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…

JWST lensed quasar dark matter survey I: Description and First Results

A. M. Nierenberg, R. E. Keeley, D. Sluse +18

The flux ratios of gravitationally lensed quasars provide a powerful probe of the nature of dark matter. Importantly, these ratios are sensitive to small-scale structure, irrespect…
