Dark Matter Constraints from Small-Scale Cosmic Structure
Ethan O. Nadler, Keir K. Rogers, Alex Drlica-Wagner
Small-scale cosmic structure provides a powerful test of the fundamental nature of dark matter (DM). A wide range of DM models impact matter clustering on small scales, including w…
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…
Mixed Dark Matter: Limits from the Milky Way Satellite Galaxies
Wendy Crumrine, Dominic Pang, Ethan O. Nadler +2
The Standard Model of particle physics contains a diverse set of particle species, motivating the possibility of a similarly complex dark sector. Here we study two-component dark m…
Warm, not Fuzzy: Generalized Ultralight Dark Matter Limits from Milky Way Satellites
Ethan O. Nadler, Mustafa A. Amin, Risa H. Wechsler +3
We generalize lower limits on the dark matter (DM) particle mass derived from Milky Way (MW) satellite galaxy abundances to scenarios in which DM is an ultralight scalar field…
The Non-universal Pseudo Phase-Space Density Profiles of Symphony Host Halos
Bocheng Feng, Ethan O. Nadler, S. Peng Oh +1
Cosmological N-body simulations have long suggested that the pseudo phase-space density (PPSD), , of cold dark matter haloes follows the universal relation $ρ/σ^3 \propto r^…
Strong-lensing Perturber Signatures in Self-interacting Dark Matter Simulations
Demao Kong, Ethan O. Nadler, Hai-Bo Yu
Motivated by recent detections of low-mass perturbers in strong gravitational lensing systems, we investigate analogs of these objects in the Concerto suite, a set of cosmological…
