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…
A model of polymer gravitational waves: theory and some possible observational consequences
Angel Garcia-Chung, James B. Mertens, Saeed Rastgoo +2
We propose a polymer quantization scheme to derive the effective propagation of gravitational waves on a classical Friedmann-Lemaitre-Robertson-Walker (FLRW) spacetime. These waves…
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…
