We present details of numerical simulations of the gravitational radiation produced by a first order thermal phase transition in the early universe. We confirm that the dominant source of gravitational waves is sound waves generated by the expanding bubbles of the low-temperature phase. We demonstrate that the sound waves have a power spectrum with a power-law form between the scales set by the average bubble separation (which sets the length scale of the fluid flow Lf) and the bubble wall… 
Gravitational waves from first-order phase transitions: ultra-supercooled transitions and the fate of relativistic shocks
We study the gravitational wave (GW) production in extremely strong first order phase transitions where the vacuum energy density dominates the plasma energy density, α ≳ 1. In such transitions,
Gravitational waves from cosmological first order phase transitions
First order phase transitions in the early Universe generate gravitational waves, which may be observable in future space-based gravitational wave observatiories, e.g. the European eLISA satellite
Sound Shell Model for Acoustic Gravitational Wave Production at a First-Order Phase Transition in the Early Universe.
TLDR
The detailed dependence of the power spectrum on the wall speed and the other parameters of the phase transition raises the possibility of their constraint or measurement at a future space-based gravitational wave observatory such as LISA.
Gravitational waves from vacuum first-order phase transitions: From the envelope to the lattice
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 spectrum at high wave
Gravitational waves from first order cosmological phase transitions in the Sound Shell Model
We calculate gravitational wave power spectra from first order early Universe phase transitions using the Sound Shell Model. The model predicts that the power spectrum depends on the mean bubble
Gravitational waves from bubble dynamics: beyond the envelope
We study gravitational-wave production from bubble dynamics (bubble collisions and sound waves) during a cosmic first-order phase transition with an analytic approach. We first propose modeling the
A hybrid simulation of gravitational wave production in first-order phase transitions
The LISA telescope will provide the first opportunity to probe the scenario of a first-order phase transition happening close to the electroweak scale. In thermal transitions, the main contribution
Sound velocity effects on the phase transition gravitational wave spectrum in the sound shell model
A cosmological first-order phase transition gravitational wave could provide a novel approach to studying the early Universe. In most cases, the acoustic gravitational wave from the sound wave
