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…
HydroGrav: Precise hydrodynamics and gravitational waves for cosmological phase transitions
Flynn Linton, William Searle, Xiao Wang +1
We present HydroGrav, a C++ code used to construct self-similar fluid profiles, using the exact equation of state determined directly from the effective potential, for any particle…
Light rings and optical appearances of naked singularities, solitons, and black holes in beyond Horndeski gravity
Hyat Huang, Jutta Kunz, Rashmi Uniyal +1
We investigate the geodesic structure and optical appearance of compact objects with primary scalar hair in shift- and parity-symmetric beyond Horndeski gravity. The analytic solut…
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…
