Fuzzy cold dark matter

Fuzzy cold dark matter is a hypothetical form of cold dark matter proposed to solve the cuspy halo problem. It would consist of extremely light scalar particles with masses on the order of  eV. Fuzzy cold dark matter halos in dwarf galaxies would manifest wave behavior on astrophysical scales, and the cusps would be avoided through the Heisenberg uncertainty principle.[1]

Fuzzy cold dark matter is a limit of scalar field dark matter without self-interaction.[2][3]
