Extracting Gravitational Waves Induced by Plasma Turbulence in the Early Universe through an Averaging Process
David Garrison, Christopher Ramirez
This work is a follow-up to the paper, "Numerical Relativity as a Tool for Studying the Early Universe". In this article, we determine if cosmological gravitational waves can be ac…
Gauge Field Turbulence as a Cause of Inflation in Chern-Simons Modified Gravity
David Garrison
In this paper, we study the dynamics of the Chern-Simons Inflation Model proposed by Alexander, Marciano and Spergel. According to this model, inflation begins when a fermion curre…
Numerical Relativity as a tool for studying the Early Universe
David Garrison
Numerical simulations are becoming a more effective tool for conducting detailed investigations into the evolution of our universe. In this article, we show how the framework of nu…
Did Gravitational Waves Affect the Evolution of the Universe?
David Garrison
As Cosmologists struggle to understand the evolution of our universe, an often over-looked element is the affect of gravitational radiation on the primordial plasma field. This app…
Black Hole Spectroscopy: Testing General Relativity through Gravitational Wave Observations
Olaf Dreyer, Bernard Kelly, Badri Krishnan +3
Assuming that general relativity is the correct theory of gravity in the strong field limit, can gravitational wave observations distinguish between black hole and other compact ob…
Notes on causal differencing in ADM/CADM formulations: a 1D comparison
Luis Lehner, Mijan Huq, David Garrison
Causal differencing has shown to be one of the promising and successful approaches towards excising curvature singularities from numerical simulations of black hole spacetimes. So…
