Cosmological Constraints on Scalar Field Dark Matter

Abstract

This paper aims to put constraints on the parameters of the Scalar Field Dark Matter (SFDM) model, when dark matter is described by a free real scalar field filling the whole Universe, plus a cosmological constant term. By using a compilation of 51 $H(z)$ data and 1048 Supernovae data from Panteon, a lower limit for the mass of the scalar field was obtained, $m\ge 5.1\times 10^{-34}$eV and $H_0=69.5_{-2.1}^{+2.0}{\text{ km s}}^{-1}{\text{Mpc}}^{-1}$. Also, the present dark matter density parameter was obtained as ${\Omega }_{\varphi }=0.230_{-0.031}^{+0.033}$ at $2\sigma$ confidence level. The results are in good agreement to standard model of cosmology, showing that SFDM model is viable in describing the dark matter content of the universe.
