Gravitational waves from cosmological phase transitions (PRETALK for students at 15:30 h)
I will discuss the state-of-the-art of predicting a stochastic background of gravitational waves produced by cosmological first-order phase transitions. I focus on recent developments in understanding the dynamics of the primordial fluid after percolation and how to connect simulation results to observations and model building. Finally, I discuss the possibility to interpret the NanoGrav excess with this kind of signal.
