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…
