Most efforts to detect signatures of dynamical dark energy are focused on late times, $z \lesssim 2$, where the dark energy component begins to dominate the cosmic energy density. Many theoretical models involving dynamical dark energy exhibit a 'freezing' equation of state however, where $w \to -1$ at late times, with a transition to a 'tracking' behaviour at earlier times (with $w \gg -1$ at sufficiently high redshift). In this paper, we study whether large-scale structure surveys in the post… Expand

The Rise of Dark Energy
A frontier for the next generation of cosmic surveys after the ones now getting underway will be pushing to higher redshift, earlier in the evolution of the universe. Cosmicly, this is not simply aExpand
Testing the quasar Hubble diagram with LISA standard sirens
Quasars have recently been used as an absolute distance indicator, extending the Hubble diagram to high redshift to reveal a deviation from the expansion history predicted for the standard,Expand


Early dark energy cosmologies
We propose a novel parameterization of the dark energy density. It is particularly well suited to describe a non-negligible contribution of dark energy at early times and contains only threeExpand
Phenomenology of dark energy: general features of large-scale perturbations
We present a systematic exploration of dark energy and modified gravity models containing a single scalar field non-minimally coupled to the metric. Even though the parameter space is large, byExpand
Early dark energy at high redshifts: status and perspectives
Early dark energy models, for which the contribution to the dark energy density at high redshifts is not negligible, influence the growth of cosmic structures and could leave observable signaturesExpand
Dark Energy in the Dark Ages
Non-negligible dark energy density at high redshifts would indicate dark energy physics distinct from a cosmological constant or reasonable' canonical scalar fields. Such dark energy can beExpand
Dark energy at early times, the Hubble parameter, and the string axiverse
Precise measurements of the cosmic microwave background (CMB) power spectrum are in excellent agreement with the predictions of the standard $\mathrm{\ensuremath{\Lambda}}\mathrm{CDM}$ cosmologicalExpand
Dark energy in Horndeski theories after GW170817: A review
The gravitational wave (GW) event GW170817 from a binary neutron star merger together with the electromagnetic counterpart showed that the speed of GWs [Formula: see text] is very close to that ofExpand
Early Dark Energy can Resolve the Hubble Tension.
This work considers two physical models for this early dark energy EDE, one involving an oscillating scalar field and another a slowly rolling field, and performs a detailed calculation of the evolution of perturbations in these models. Expand
Limits on Dark Radiation, Early Dark Energy, and Relativistic Degrees of Freedom
Recent cosmological data analyses hint at the presence of an extra relativistic energy component in the early universe. This component is often parametrized as an excess of the effective neutrinoExpand
We present a framework for forecasting cosmological constraints from future neutral hydrogen intensity mapping experiments at low to intermediate redshifts. In the process, we establish a simple wayExpand
Does the Hubble constant tension call for new physics
The Λ Cold Dark Matter model (ΛCDM) represents the current standard model in cosmology. Within this, there is a tension between the value of the Hubble constant, H0, inferred from local distanceExpand
