Model-dependent analysis method for energy budget of the cosmological first-order phase transition
Xiao Wang, Chi Tian, Fa Peng Huang
The kinetic energy of the fluid shell in the cosmological first-order phase transition is crucial for predicting the gravitational wave signals generated by the sound wave mechanis…
Accelerating spherical harmonic transforms for a large number of sky maps
Chi Tian, Siyu Li, Hao Liu
The spherical harmonic transform is a powerful tool in the analysis of spherical data sets, such as the cosmic microwave background data. In this work, we present a new scheme for…
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…
Gravitational Waves from Fully General Relativistic Oscillon Preheating
Xiao-Xiao Kou, James B. Mertens, Chi Tian +1
As long-lived quasi-solitons from the fragmentation of a scalar condensate, oscillons may dominate the preheating era after inflation. During this period, stochastic gravitational…
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…
