This paper is a review on the observational Hubble parameter data that have gained increasing attention in recent years for their illuminating power on the dark side of the universe: the dark matter, dark energy, and the dark age. Currently, there are two major methods of independent observational measurement, which we summarize as the “differential age method” and the “radial BAO size method.” Starting with fundamental cosmological notions such as the spacetime coordinates in an expanding… Expand

Study of the dark components of the Universe with the Euclid mission
The concordance model of cosmology, called ΛCDM, is a success, since it is able to reproduce the main cosmological observations with great accuracy and only few parameters. However, it predicts theExpand
Revisit of constraints on dark energy with Hubble parameter measurements including future redshift drift observations
We investigate whether the current Hubble parameter $H(z)$ measurements could help improve the constraints on dark energy on the basis of the mainstream cosmological probes including the type IaExpand
Observational constraints on unified dark matter including Hubble parameter data
Abstract We constrain a unified dark matter (UDM) model from the latest observational data. This model assumes that the dark sector is degenerate. Dark energy and dark matter are the same component.Expand
Interaction between dark energy and dark matter: observational constraints from OHD, BAO, CMB and SNe Ia
In order to test if there is energy transfer between dark energy (DE) and dark matter (DM), we investigate cosmological constraints on two forms of nontrivial interaction between the DM sector andExpand
Constraining dark energy with Hubble parameter measurements: an analysis including future redshift-drift observations
The nature of dark energy affects the Hubble expansion rate (namely, the expansion history) H(z) by an integral over w(z). However, the usual observables are the luminosity distances or the angularExpand
Constraints on unified models for dark matter and dark energy using H(z)

Observational constraint on the interacting dark energy models including the Sandage–Loeb test

Complementary cosmological tests of RSII brane models
In this paper we explore observational bounds on flat and non-flat cosmological models in type II Randall–Sundrum branes. In a first analysis, we consider current measurements of the expansion rateExpand
Cosmological constraints on holographic dark energy models under the energy conditions
