GUT-Scale Primordial Black Holes: Consequences and Constraints
Richard Anantua, Richard Easther, John T. Giblin
A population of very light primordial black holes which evaporate before nucleosynthesis begins is unconstrained unless the decaying black holes leave stable relics. We show that g…
Gravitational Waves From the End of Inflation: Computational Strategies
Richard Easther, John T. Giblin, Eugene A. Lim
Parametric resonance or preheating is a plausible mechanism for bringing about the transition between the inflationary phase and a hot, radiation dominated universe. This epoch res…
Gravitational Wave Production At The End Of Inflation
Richard Easther, John T. Giblin, Eugene A. Lim
We consider gravitational wave production due to parametric resonance at the end of inflation, or ``preheating''. This leads to large inhomogeneities which source a stochastic back…
The Hubble Slow Roll Expansion for Multi Field Inflation
Richard Easther, John T Giblin
We examine the dynamics of inflation driven by multiple, interacting scalar fields and derive a multi field version of the Hubble slow roll expansion. We show that the properties o…
