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…
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…
