Vortex Structures in a Rotating BEC Dark Matter Component

Figure 1

Rotation curves based on BEC DM with a vortex lattice for different halo sizes 𝑟₀=8 (full), 𝑟₀=4 (dotted), and 𝑟₀=2 kpc (dashed). The vortex core size is 5 kpc. In the left column the distance between vortices is 2.5 kpc, whereas it is 1 kpc in the right column. Upper row is for a triangular lattice, and the lower one is for a square lattice.
