Late-time cosmology in a (phantom) scalar-tensor theory: Dark energy and the cosmic speed-up

We consider late-time cosmology in a (phantom) scalar-tensor theory with an exponential potential, as a dark-energy model with equation of state parameter close to $\ensuremath{-}1$ (a bit above or below this value). Scalar (and also other kinds of) matter can be easily taken into account. An exact ... View More
