Gravitational waves (GWs) were recently detected for the first time. This revolutionary
discovery opens a new way of learning about particle physics through GWs from first-order …

The first direct measurement of gravitational waves by the LIGO and Virgo collaborations
has opened up new avenues to explore our Universe. This white paper outlines the …

We investigate the potential for observing gravitational waves from cosmological phase
transitions with LISA in light of recent theoretical and experimental developments. Our …

A bstract We critically examine the magnitude of theoretical uncertainties in perturbative
calculations of fist-order phase transitions, using the Standard Model effective field theory as …

What is the maximum possible strength of a first-order electroweak phase transition and the
resulting gravitational wave (GW) signal? While naively one might expect that supercooling …

We present results from large-scale numerical simulations of a first order thermal phase
transition in the early Universe, in order to explore the shape of the acoustic gravitational …

A novel mechanism for the primordial black hole (PBH) production is proposed as a natural
and inevitable consequence of general first-order phase transitions without reference to …

We survey systematically the general parametrisations of particle-physics models for a first-
order phase transition in the early universe, including models with polynomial potentials …

We update predictions for the gravitational wave (GW) signal from a strongly supercooled
phase transition in an illustrative classically conformal U (1) B− L model. We implement∝ γ …

A bstract 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 …
