About

In many BSM physics scenarios the early Universe went through a first-order phase transition. The gravitational waves produced in the transition may be observable in future gravitational wave detectors, such as the LISA gravitational wave space mission. In order to fully utilize the observations the gravitational wave production must be calculated to high precision. In this talk I discuss the importance of numerical simulations in the analysis of phase transitions, from BSM thermodynamics, critical bubble nucleation and the subsequent hydrodynamic evolution and gravitational wave production.

This talk is part of the Advancing gravitational wave predictions from cosmological first-order phase transitions .
