Resonant Gravitational Wave Amplification - Axion and Inflaton
Bruce A. Bassett
We demonstrate the parametric amplification of the stochastic gravitational wave background during inflationary reheating and during axion/moduli oscillations. This amplification e…
Inflationary Reheating Classes via Spectral Methods
Bruce A. Bassett
Inflationary reheating is almost completely controlled by the Floquet indices, . Using spectral theory we demonstrate that the stability bands (where ) of the Mathieu…
Geometric Reheating after Inflation
Bruce A. Bassett, Stefano Liberati
Inflationary reheating via resonant production of non-minimally coupled scalar particles with only gravitational coupling is shown to be extremely strong, exhibiting a negative cou…
Shrinking II -- The Distortion of the Area Distance-Redshift Relation in Inhomogeneous Isotropic Universes
Nazeem Mustapha, B. A. Bassett, Charles Hellaby +1
This paper and the others in the series challenge the standard model of the effects of gravitational lensing on observations at large distances. We show that due to the cumulative…
The Preheating - Gravitational Wave Correspondence
Bruce A. Bassett
The gravitational wave equations form a parametric resonance system during oscillatory reheating after inflation, when cast in terms of the electric and magnetic parts of the Weyl…
Gravito-electromagnetism
Roy Maartens, Bruce A. Bassett
We develop and apply a fully covariant 1+3 electromagnetic analogy for gravity. The free gravitational field is covariantly characterized by the Weyl gravito-electric and gravito-m…
