SSMtools

Functions for calculating velocity and gravitational wave power spectra from a first-order phase transition in the Sound Shell Model.

The Sound Shell Model is discussed in further detail in the article Sound Shell Model for Acoustic Gravitational Wave Production at a First-Order Phase Transition in the Early Universe (Hindmarsh, 2018)
