PHANTOM is a public MATLAB/Octave toolbox for linear field statistics and halo observables in dark matter cosmology, validated to sub-percent agreement with Python packages colossus, hmf, and halomod.
Simulations show fuzzy dark matter fraction up to 0.3 suppresses low-mass halos in mixed DM models, and a redshift- and fraction-dependent suppression function maps CDM HMFs to MDM HMFs within 0.1-0.2 dex accuracy for z=1-4.
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.
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.
