Description
I will present numerical results of strong phase transitions using the so-called Higgsless approach and recent theoretical developments to describe the GW production extending the stationary UETC assumption for sound waves to a locally stationary UETC that allows us to describe decaying sources of gravitational waves. The source of GWs corresponding to compressional motion (sound waves in their linear regime) decays for strong phase transitions due to the development of non-linearities in the fluid perturbations induced by the expansion and collision of broken-phase bubbles. I will also present a new public code (cosmoGW) available for templates and models of cosmological GWs that include recent developments for GW production from compressional (sound waves and non-linear compressional motion) and vortical (MHD turbulence) motion in the primordial plasma.
