Using Gravitational Wave Signals to Disentangle Early Matter Dominated Epochs
Matthew Pearce, Lauren Pearce, Graham White +1
Curvature perturbations induce gravitational waves (GWs) at second order, contributing to the stochastic gravitational wave background. The resulting gravitational wave spectrum is…

Gravitational Wave Signals From Early Matter Domination: Interpolating Between Fast and Slow Transitions
Matthew Pearce, Lauren Pearce, Graham White +1
An epoch of matter domination in the early universe can enhance the primordial stochastic gravitational wave signal, potentially making it detectable to upcoming gravitational wave…

Falsifying Pati-Salam models with LIGO
Peter Athron, Csaba Balázs, Tomás E. Gonzalo +1
We demonstrate that existing gravitational wave data from LIGO already places constraints on well motivated Pati-Salam models that allow the Standard Model to be embedded within gr…
