Fuzzy cold dark matter: the wave properties of ultralight particles

    Abstract

    Cold dark matter (CDM) models predict cuspy dark matter halo profiles and an abundance of low mass halos. Although these models yield significant results, they require self-interactions wildly in excess of those expected for weekly interacting massive particles or axions. A solution is proposed, involving free particles only. The solution emphasizes that dark matter halos are stable on small scales for the same reason that the hydrogen atom is stable.
