What is flat ΛCDM, and may we choose it?
Stefano Anselmi, Matthew F. Carney, John T. Giblin +5
The Universe is neither homogeneous nor isotropic, but it is close enough that we can reasonably approximate it as such on suitably large scales. The inflationary--Cold Dark Mat…
Accurate relativistic observables from post-processing light cone catalogues
Chi Tian, Matthew F. Carney, James B. Mertens +1
We introduce and study a new scheme to construct relativistic observables from post-processing light cone data. This construction is based on a novel approach, LC-Metric, which tak…
On the question of measuring spatial curvature in an inhomogeneous universe
Chi Tian, Stefano Anselmi, Matthew F. Carney +3
The curvature of a spacetime, either in a topological sense, or averaged over super-horizon-sized patches, is often equated with the global curvature term that appears in Friedmann…
The Limited Accuracy of Linearized Gravity
John T. Giblin, James B. Mertens, Glenn D. Starkman +1
Standard cosmological models rely on an approximate treatment of gravity, utilizing solutions of the linearized Einstein equations as well as physical approximations. In an era of…
