Simple test with rotation curves for the multistate scalar field dark matter model

We use the concept of coadded rotation curves of Salucci et al. to investigate the properties of axisymmetric multistate scalar field dark matter (SFDM) halos in low surface brightness (LSB) galaxies and dwarf disc galaxies. To this end, we expand the wave function of the scalar field into its multistates and solve the field equations numerically. We fit their rotation curves in two -state configurations finding that a two -state configuration fits better than the single ground -state (soliton) configuration in the dwarf disc and in the smaller of the LSB galaxies. We obtain a SFDM mass mu = 2.38 +/- 0.12 x 10 - 23 eV /c 2 for the dwarf disc galaxies and mu = 1.05 +/- 0.14 x 10 - 23 eV /c 2 for the smaller of the LSB galaxies. For the larger of the LSB galaxies a mass of the order of mu = O (10 - 24 ) - O (10 - 25 ) eV /c 2 is obtained, where the mass mu is the effective mass measured by an outside observer due to the finite temperature of the SFDM in the galaxy.
