Tidal Heating of Stellar Clusters in Fuzzy Dark Matter Halos

The study investigates how ultra-light dark matter halos affect stellar clusters in dwarf galaxies. It found that when the de Broglie wavelength is large compared to cluster size, tidal heating dominates over diffusive heating, causing exponential growth. This shifts the constraints on dark matter particle mass from simple lower bounds to needing detailed knowledge of halo structure and orbital history.
