About
The Sound Shell Model provides a computationally efficient way of calculating the gravitational wave spectra of cosmological first-order phase transitions. Based on the Sound Shell Model, we have created the simulation framework PTtools and integrated it with our web-based plotting utility PTPlot.
In this talk I will show how to use PTtools and PTPlot to easily compute Sound Shell Model power spectra for arbitrary equations of state. This is crucial to improving the quality of predictions of stochastic backgrounds of gravitational waves from phase transitions, including equations of state beyond the bag model with temperature- and phase-dependent sound speeds..
