Description
I will describe new cosmological zoom-in simulation suites that accurately resolve small-scale structure in the presence of novel dark matter physics. These simulations target Milky Way and strong lens analogs with initial conditions appropriate for a large variety of warm, interacting, and fuzzy dark matter models at and below current observational limits. Several of these simulations include strong, velocity-dependent dark matter self-interactions that yield distinctive predictions for structure on dwarf galaxy scales. Finally, I will present a new approach to simulate dark matter-baryon scattering in hydrodynamic simulations, and preliminary results.
