Abstract

In this work we analyse the dynamics of the bubbles responsible of cosmological phase transitions in the early Universe. To do so, the hydrodynamic profiles of a relativistic bubble are studied depending on its wall velocity, which characterises three different fluid velocity and enthalpy profiles: deflagrations, detonations and hybrids. The differences between the velocity profiles of these regimes may lead to different gravitational waves power spectra, which are potentially detectable in the foreseeable future and thus of great interest in cosmology
