Where: Danish IAS conference room

Violent events in the very early Universe, when its age was less than 10 picoseconds, may have produced gravitational waves which can be observed in future space-based gravitational wave observatories, like the LISA satellite constellation scheduled for launch in 2034. I discuss how strong first order phase transitions produce gravitational waves, and how the signal can be used to obtain information about beyond the Standard Model particle physics.
