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…
Theoretical consistency and phenomenology of supercooled cosmological phase transitions
Maciej Kierkla
This dissertation investigates a supercooled phase transition (PT) in the early Universe. Using high-temperature dimensional reduction (DR), we compute the NLO thermal bubble nucle…
Thermodynamical uncertainties for primordial black holes from cosmological phase transitions
Maciej Kierkla, Nicklas Ramberg, Philipp Schicho +1
Strongly supercooled first-order phase transitions have been proposed as a primordial black hole (PBH) production mechanism. While previous works rely on simplified models with lim…
Finite-temperature bubble nucleation with shifting scale hierarchies
Maciej Kierkla, Philipp Schicho, Bogumila Swiezewska +2
Focusing on supercooled phase transitions in models with classical scale symmetry, we formulate a state-of-the art framework for computing the bubble-nucleation rate, accounting fo…
