Cosmic acceleration and phantom crossing in $f(T)$-gravity (1112.4700v1)
Published 17 Dec 2011 in physics.gen-ph and astro-ph.CO
Abstract: In this paper, we propose two new models in $f(T)$ gravity to realize universe acceleration and phantom crossing due to dark torsion in the formalism. The model parameters are constrained and the observational test are discussed. The best fit results favors an accelerating universe with possible phantom crossing in the near past or future followed respectively by matter and radiation dominated era.
