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 $\mu \sim (10^{-23} - 10^{-24})\rm{eV}/c^2$. 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.

  1. Testing Scalar Field Dark Matter models in M31 galaxy through the Rotation Curve analysis

    astro-ph.CO 2026-04 unverdicted novelty 4.0 of 10

    Fuzzy dark matter with smooth cored halos provides the most consistent description of M31's rotation curve among scalar field models when paired with a two-bulge baryonic configuration.
