Discrimination between dark energy models from recent observations

Abstract

We discriminate between theoretical models of dark energy from recent observations. We place constraints on dark energy models from the background cosmology by using the data of supernovae Ia, cosmic microwave background, and baryon acoustic oscillations. We further show that the recent measurement of the peculiar velocity of galaxies is powerful to constrain modified gravity models.
