Gravitational waves (GWs) emitted during the first-order phase transitions (FOPTs) of strongly coupled quantum field theories (QFTs) present a significant challenge for accurate prediction due to the nature of the strong coupling. In this talk, we will demonstrate a method for predicting the GW spectra of strongly coupled QFTs by combining holography with lattice data from pure SU(N) Yang-Mills theory. We will explore how holography can be employed to construct an effective action and, with this action in hand, investigate bubble nucleation as a means of estimating the gravitational wave spectra. Finally, we will discuss the broader phenomenological implications of our findings.
