Dynamical dark energy in light of cosmic distance measurements II: a study using current observations

We extract key information of dark energy from current observations of BAO, OHD and \(H_0\), and find hints of dynamical behaviour of dark energy. In particular, a dynamical dark energy model whose equation of state crosses \(-1\) is favoured by observations. We also find that the Universe has start...

description We extract key information of dark energy from current observations of BAO, OHD and \(H_0\), and find hints of dynamical behaviour of dark energy. In particular, a dynamical dark energy model whose equation of state crosses \(-1\) is favoured by observations. We also find that the Universe has started accelerating at a lower redshift than expected.
