abstract
We provide an easy method to obtain the kinetic energy fraction in gravitational waves, generated during a cosmological first-order phase transition, as a function of only the wall velocity and quantities that can be determined from the particle physics model at the nucleation temperature. This generalizes recent work that achieved this goal for detonations. Here we present the corresponding results for deflagrations and hybrids. Unlike for detonations, the sound speed in the symmetric phase also enters the analysis. We perform a detailed comparison between our model-independent approach and other approaches in the literature. We provide a Python code snippet to determine the kinetic energy fraction $K$ as a function of the wall velocity, the two speeds of sound and the strength parameter of the phase transition. We also assess how realistic sizable deviations in speed of sound are close to the phase transition temperature in a specific model.

Defines peak-integrated sensitivity curves (PISCs) that fold in the expected spectral shape of gravitational waves from cosmological phase transitions and supplies semianalytical fits plus public data for major detectors.
Polyakov loop contributions to the thermal effective potential soften electroweak phase transitions, disfavoring first-order transitions and suppressing gravitational-wave signals.
Applies high-T dimensional reduction for the first time to a classically scale-invariant model, computes NLO nucleation rate via determinants, and predicts LISA-detectable GW from supercooled PT in SU(2)cSM.
Filtered Dark Matter hydrodynamics during first-order phase transitions is modeled as a two-component fluid, yielding detonation-like and deflagration-like solutions in ballistic and local thermal equilibrium regimes that change relic abundance predictions.
Precision study of dark sector phase transitions finds PTA-favored parameters near EFT breakdown with disfavored GW signals after higher-order corrections.
HydroGrav code computes self-similar fluid profiles and GW spectra using exact EOS from effective potentials for EWPT models, identifying parameter regions in a Z2 SM extension where simplified EOS differ in amplitude and shape, with LISA SNR estimates.
Computes dimension-six operators in finite-temperature massive scalar QED via heat kernel methods and evaluates their combined effect with the Polyakov loop on first-order phase transition thermodynamics.
