The Rise of Dark Energy
Eric V. Linder

TL;DR
This paper discusses the evolution of dark energy, showing it became dominant recently but still contributed significantly at higher redshifts, and predicts future galaxy surveys can detect its rise with high confidence.
Contribution
It provides model-independent constraints on dark energy’s fraction over cosmic time and forecasts detection capabilities of upcoming galaxy surveys.
Findings
Dark energy's dominance began around z≈0.7
Dark energy contributed >5% up to z≈2.5
Future surveys can detect dark energy's rise at 3σ confidence
Abstract
While dark energy has dominated cosmic dynamics only since , its energy density was still of the total out to . We calculate model independent constraints on its fraction from future galaxy surveys, finding that the rise of dark energy could be detected at nearly out to .
