Thawing Quintessence: Priors, evidence, and likely trajectories
David Shlivko
We perform a Bayesian comparison between thawing quintessence and a cosmological constant, incorporating theoretically motivated priors on the phenomenological Padé-w parameters u…
Assessing observational constraints on dark energy
David Shlivko, Paul Steinhardt
Observational constraints on time-varying dark energy ({\it e.g.}, quintessence) are commonly presented on a - plot that assumes the equation of state of dark energy stri…
Phantom-Crossing Dark Energy and the Tug-of-War
David Shlivko, Vivian Poulin
Recent analyses combining data from the cosmic microwave background (CMB), baryon acoustic oscillations (BAO), and Type Ia supernovae (SN) have revealed a tentative observational p…
Optimal parameterizations for observational constraints on thawing dark energy
David Shlivko, Paul J. Steinhardt, Charles L. Steinhardt
Time-varying dark energy is often modeled in observational analyses through generic parameterizations of its equation of state , which typically use two free parameters $\{w_…
