Thermalization effects on the dynamics of growing vacuum bubbles
Tomasz Krajewski, Marek Lewicki, Martin Vasar +3
We study the evolution of growing vacuum bubbles. The bubble walls interact with the surrounding fluid and may, consequently, reach a terminal velocity. If the mean free path of th…
Impact of theoretical uncertainties on model parameter reconstruction from GW signals sourced by cosmological phase transitions
Marek Lewicki, Marco Merchand, Laura Sagunski +2
Different computational techniques for cosmological phase transition parameters can impact the Gravitational Wave (GW) spectra predicted in a given particle physics model. To scrut…
Dynamics of false vacuum bubbles with trapped particles
Marek Lewicki, Kristjan Müürsepp, Joosep Pata +3
We study the impact of the ambient fluid on the evolution of collapsing false vacuum bubbles by simulating the dynamics of a coupled bubble-particle system. A significant increase…
The Scalar Singlet Extension of the Standard Model: Gravitational Waves versus Baryogenesis
John Ellis, Marek Lewicki, Marco Merchand +2
We study the possible gravitational wave signal and the viability of baryogenesis arising from the electroweak phase transition in an extension of the Standard Model (SM) by a scal…
Gravitational waves from first-order cosmological phase transitions: lifetime of the sound wave source
John Ellis, Marek Lewicki, José Miguel No
We survey systematically the general parametrisations of particle-physics models for a first-order phase transition in the early universe, including models with polynomial potentia…
Gravitational Wave Bursts as Harbingers of Cosmic Strings Diluted by Inflation
Yanou Cui, Marek Lewicki, David E. Morrissey
A standard expectation of primordial cosmological inflation is that it dilutes all relics created before its onset to unobservable levels. We present a counterexample to this expec…
