Gravitational waves from vacuum first order phase transitions II: from thin to thick walls
Daniel Cutting, Elba Granados Escartin, Mark Hindmarsh +1
In a vacuum first-order phase transition, gravitational waves are generated from collision of bubbles of the true vacuum. The spectrum from such collisions takes the form of a brok…

Vorticity, kinetic energy, and suppressed gravitational wave production in strong first order phase transitions
Daniel Cutting, Mark Hindmarsh, David J. Weir
We have performed the first 3-dimensional simulations of strong first-order thermal phase transitions in the early Universe. For deflagrations, we find that the rotational componen…

Gravitational waves from vacuum first-order phase transitions: from the envelope to the lattice
Daniel Cutting, Mark Hindmarsh, David J. Weir
We conduct large scale numerical simulations of gravitational wave production at a first order vacuum phase transition. We find a power law for the gravitational wave power spectru…
