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…

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.…

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…
