Phase transitions in an expanding universe: stochastic gravitational waves in standard and non-standard histories
Phase transitions in an expanding universe: stochastic gravitational waves in standard and non-standard histories
We undertake a careful analysis of stochastic gravitational wave production from cosmological phase transitions in an expanding universe, studying both a standard radiation as well as a matter dominated history. We analyze in detail the dynamics of the phase transition, including the false vacuum fraction, bubble lifetime distribution, bubble number …
