Gravitational Wave Echoes of the First Order Phase Transition in a Kination-Induced Big Bang
Richard Casey, Katherine Freese, Evangelos I. Sfakianakis
Gravitational waves (GWs) produced during first-order phase transitions (FOPTs) in the early universe provide a powerful probe of nonstandard cosmological histories. We study GW pr…
