Strong Constraints on Fuzzy Dark Matter from Ultrafaint Dwarf Galaxy Eridanus II

The fuzzy dark matter (FDM) model treats DM as a bosonic field with astrophysically large de Broglie wavelength. A striking feature of this model is \(\mathcal{O}(1)\) fluctuations in the dark matter density on time scales which are shorter than the gravitational timescale. Including for the first t...
