How large are curvature perturbations from slow first-order phase transitions? A gauge-invariant analysis
Xiao Wang, Csaba Balázs, Ran Ding +1
When strongly supercooled cosmological first-order phase transitions (FOPTs) are sufficiently slow, super-horizon inhomogeneities can be generated. We compute these super-horizon c…

Nonlinear growth and amplification of phase-transition gravitational waves induced by cosmic expansion
Xiao Wang, Chi Tian, Csaba Balázs
We perform the first three-dimensional hydrodynamical simulations of cosmological first-order phase transitions in an expanding background. These simulations consistently incorpora…

DeepSSM: an emulator of gravitational wave spectra from sound waves during cosmological first-order phase transitions
Chi Tian, Xiao Wang, Csaba Balázs
We present DeepSSM, an open-source code powered by neural networks (NNs) to emulate gravitational wave (GW) spectra produced by sound waves during cosmological first-order phase tr…
