Simulations find metal-richer compact stellar systems resist disruption better in ULDM halos, with tidal fields altering stability and heating strengthening at higher particle masses when system size is much smaller than the de Broglie wavelength, implying revisions to existing constraints.
Five of seven modeled M31 dwarf spheroidals show anomalously low central DM densities at 150 pc, with star formation heating disfavored as the sole cause.
Review of fuzzy dark matter simulation techniques including governing equations, wave- and fluid-based algorithms, test problems, and public initial condition files for code benchmarking.
