Late-time phase transition and the galactic halo as a Bose liquid. II. The effect of visible matter

In a previous work, we investigated the rotation curves of galaxies assuming that the dark matter consists of ultralight bosons appearing in ‘‘late-time phase transition’’ theory. Generalizing this work, we consider the effect of visible matter and classify the types of rotation curves as we vary the fraction of the mass and extension of visible matter. We show that visible matter, in galaxies with flat rotation curves, has a mass fraction 2%–10% and it is confined within the distance fraction 10%–20%.
