Rotation curves with the multistate Scalar Field Dark Matter model

Abstract

We use the concept of co-added rotation curves of Salucci et al. to investigate the properties of axi-symmetric multistate Scalar Field Dark Matter halos in low surface brightness galaxies and dwarf disc galaxies. We fit their rotation curves in two-state configurations and we find that all of these can be well fitted with a particle mass $\mu \sim (10^{-23}-10^{-24})\mathrm{eV}/{\mathrm{c}}^2$. Comparing our results with the standard cosmological model, the well-known $\Lambda$-cold dark matter, by using the Bayesian information criterion and the Akaike information criterion, we found that our two-state model seemed to be preferred.
