From friction scaling to an efficient method for estimating bubble wall velocity
Tomasz Krajewski, Marek Lewicki, Marco Merchand +2
We present a unified description of first-order cosmological phase transition dynamics that links the phenomenological friction model employed in hydrodynamic simulations to the mi…
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…
Exploring Ultra-Slow-Roll Inflation in Composite Pseudo-Nambu-Goldstone Boson Models: Implications for Primordial Black Holes and Gravitational Waves
Marco Merchand
We study inflation driven by a scalar potential arising from composite-sector dynamics, inspired by generalized composite Higgs models. The introduction of a non-minimal coupling,…
Gravitational waves from first-order phase transitions in LISA: reconstruction pipeline and physics interpretation
Chiara Caprini, Ryusuke Jinno, Marek Lewicki +6
We develop a tool for the analysis of stochastic gravitational wave backgrounds from cosmological first-order phase transitions with LISA: we initiate a template databank for these…
Electroweak bubble wall expansion: gravitational waves and baryogenesis in Standard Model-like thermal plasma
Marek Lewicki, Marco Merchand, Mateusz Zych
Computing the properties of the bubble wall of a cosmological first order phase transition at electroweak scale is of paramount importance for the correct prediction of the baryon…
