About

The gravitational wave spectrum from sound wave contributions is typically modeled as a double-broken power law with fixed spectral slopes. However, the intermediate slope depends on phase transition parameters, which can help resolve degeneracies when reconstructing these parameters. To improve gravitational wave predictions, we provide an analytic form of this parameter dependence, derived via approximations or numerical fits, based on the sound shell model..
