Description
During a cosmological first-order phase transition, most of the latent
heat is released into thermal energy and bulk motion of the plasma. The
latter will give rise to anisotropic stress in the plasma and generate
gravitational waves when the nucleated bubbles percolate at the end of
the phase transition. In this talk I review the basic principles of
gravitational wave production and the analysis of the energy budget of
the phase transition by means of hydrodynamics. Finally, I will discuss
how these signals can be used to constrain and/or rule out specific
particle physics models.
