Constraints on the DGP Universe Using Observational Hubble parameter
arXiv:0706.2737 · doi:10.1016/j.physletb.2007.06.053
Abstract
In this work, we use observations of the Hubble parameter from the differential ages of passively evolving galaxies and the recent detection of the Baryon Acoustic Oscillations (BAO) at to constrain the Dvali-Gabadadze-Porrati (DGP) universe. For the case with a curvature term, we set a prior and the best-fit values suggest a spatially closed Universe. For a flat Universe, we set free and we get consistent results with other recent analyses.
