Quintessence-like dark matter in spiral galaxies
Through the geodesic analysis of a static and axially symmetric space time, we present conditions on the state equation of an isotropic perfect fluid p = ωd, when it is considered as the dark matter in spiral galaxies. The main conclusion is that it can be an exotic fluid (-1 < ω < -1/3) as it is found for Quintessence at cosmological scale.
