Constraints on the DGP Universe Using Observational Hubble parameter

Astrophysics 2008-11-26 v1

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 z1=0.35z_1=0.35 to constrain the Dvali-Gabadadze-Porrati (DGP) universe. For the case with a curvature term, we set a prior h=0.73±0.03h=0.73\pm0.03 and the best-fit values suggest a spatially closed Universe. For a flat Universe, we set hh free and we get consistent results with other recent analyses.
