摘 要:We extract key information on dark energy from current observations of BAO,OHD and H_(0),and find hints of dynamical behavior of dark *** particular,a dynamical dark energy model whose equation of state crosses-1 is favored by *** also find that the Universe has started accelerating at a lower redshift than expected.
