Gravitational waves from the sound of a first-order phase transition

Description

I will report on the first numerical 3+1D simulation of a thermal first-order phase transition. The simulation includes a scalar field plus a relativistic fluid. We follow the evolution and collisions of the bubbles related to the phase transition. We compute the generated gravitational wave spectrum, and find that their prime source are sound produced by the colliding bubbles.
