Acoustic gravitational waves beyond leading order in bubble over Hubble radius
Lorenzo Giombi, Jani Dahl, Mark Hindmarsh
We calculate the gravitational wave power spectrum from sound waves in a cosmological first order phase transition in the unexplored regime of large bubbles, by which we mean that…

Primordial acoustic turbulence: three-dimensional simulations and gravitational wave predictions
Jani Dahl, Mark Hindmarsh, Kari Rummukainen +1
Gravitational waves (GWs) generated by a first-order phase transition at the electroweak scale are detectable by future space-based detectors like LISA. The lifetime of the resulti…
