Non-parametric Dark Energy Degeneracies
Renée Hlozek, Marina Cortês, Chris Clarkson +1
We study the degeneracies between dark energy dynamics, dark matter and curvature using a non-parametric and non-perturbative approach. This allows us to examine the knock-on bias…
Is the Dynamics of Tracking Dark Energy Detectable?
Bruce A. Bassett, Mike Brownstone, Antonio Cardoso +5
We highlight the unexpected impact of nucleosynthesis and other early universe constraints on the detectability of tracking quintessence dynamics at late times, showing that such d…
Dynamical Dark Energy or Simply Cosmic Curvature?
Chris Clarkson, Marina Cortes, Bruce A. Bassett
We show that the assumption of a flat universe induces critically large errors in reconstructing the dark energy equation of state at z>~0.9 even if the true cosmic curvature is ve…
On what scale should inflationary observables be constrained?
Marina Cortês, Andrew R Liddle, Pia Mukherjee
We examine the choice of scale at which constraints on inflationary observables are presented. We describe an implementation of the hierarchy of inflationary consistency equations…
The consistency equation hierarchy in single-field inflation models
Marina Cortês, Andrew R Liddle
Inflationary consistency equations relate the scalar and tensor perturbations. We elucidate the infinite hierarchy of consistency equations of single-field inflation, the first of…
