If dark matter in the galactic halo is composed of bosons that form a Bose-Einstein condensate then it is likely that the rotation of the halo will lead to the nucleation of vortices. After a review of the Gross-Pitaevskii equation, the Thomas-Fermi approximation and vortices in general, we consider vortices in detail. We find strong bounds for the boson mass, interaction strength, the shape and quantity of vortices in the halo, the critical rotational velocity for the nucleation of vortices and, in the Thomas-Fermi regime, an exact solution for the mass density of a single, axisymmetric vortex.

    astro-ph.GA 2026-07 conditional novelty 6.0 of 10

    Vortex reconnections in BEC/superfluid dark matter halos produce dark-sector heating at a rate that is secular but sub-virial for relaxed non-interacting soliton cores, with the dominant uncertainty being the true vor...

  2. Vortices and rotating solitons in ultralight dark matter

    astro-ph.CO 2025-01 conditional novelty 6.0 of 10

    Rotating solitons in self-interacting ultralight dark matter form through a uniform vortex lattice, with a maximum radius about 1.59 times and a maximum rotation rate about 1.34 times the square root of the central density.
