Primordial gravitational waves from a cosmological first order phase transition has become a new window to probe physics beyond the standard model and can complement direct searches at the energy and intensity frontiers. I will briefly review recent developments of the theoretical modelling and numerical simulations of the gravitational wave production during a cosmological first order phase transition. I will then discuss in detail the dynamics of the phase transition and the modelling of the dominant acoustic production of gravitational waves in an expanding universe, based on our work.

I will introduce my recent work which forecasts the potential of bright sirens from future GW detector networks, i.e., the second-generation ground-based advanced LIGO+advanced Virgo+KAGRA+LIGO-India (HLVKI), the third-generation ground-based Einstein Telescope+two Cosmic Explorer (ET+2CE), and the space-based LISA+Taiji, on cosmology and modified gravity theory. The construction of joint Hubble diagram from these networks will be briefly introduced and then the results based.
