Fig. 4.


Density profile of the srBEC model (colored surface), as a function of the distance measured from the rotation axis of the galaxy in its equatorial plane (R, on the x-axis), and of the angular velocity (ω, on the y-axis). For comparison we also indicate the ρ = 0 level. The model parameters are as follows: the central density, ρc = 1 × 10−24 g cm−3, and the size of the BEC halo in static limit is ℛ = 4 kpc (left panel) and ℛ = 16 kpc (right panel).
