27. Theory colloquium: New physics with the gravitational waves form early universe phase transitions

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...

33. Gravitational waves from first order phase transitions: progress and problems

I review calculations of gravitational waves from the fluid flows generated by first order phase transition in the early universe, summarise the current status in simulations and modelling, and suggest areas where further progress can be made in preparation for the LISA mission.
