Theoretical uncertainties in reconstructing model parameters with gravitational waves from supercooled phase transitions
Maciej Kierkla, Marek Lewicki, Philipp Schicho +2
Future interferometers may detect a gravitational-wave (GW) signal from a cosmological first-order phase transition. Reconstructing the underlying particle-physics model from such…

Imprints of Reheating Dynamics on Gravitational Waves from Phase Transitions
Basabendu Barman, Maciej Kierkla, Marek Lewicki +1
We investigate how perturbative reheating after inflation modifies the primordial gravitational wave (GW) spectrum generated by cosmological phase transitions. Within a specific in…
