Late-time Phase transition and the Galactic halo as a Bose Liquid: (II) the Effect of Visible Matter
Abstract
In the previous work, we investigated the rotation curves of galaxies assuming that the dark matter consists of ultra light boson 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 extention of visible matter. We show that visible matter, in galaxies with flat rotation curves, has mass fraction 2\% 10\% and it is confined within the distance fraction 10\% 20\%.
