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 cosmology5 p.application/pdfengcc-by-nc-nd (c) Ponce de León, 2022http://creativecommons.org/licenses/by-nc-nd/3.0/es/CosmologiaTransformacions de fase (Física estadística)Treballs de fi de grauCosmologyPhase transformations (Statistical physics)Bachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
