Sound Shell Model for Acoustic Gravitational Wave Production at a First-Order Phase Transition in the Early Universe

Sound Shell Model for Acoustic Gravitational Wave Production at a First-Order Phase Transition in the Early Universe
Mark Hindmarsh
A model for the acoustic production of gravitational waves at a first-order phase transition is presented. The source of gravitational radiation is the sound waves generated by the explosive growth of bubbles of the stable phase. The model assumes that the sound waves are linear and that their power...
