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 …

Abstract The Laser Interferometer Space Antenna (LISA) has two scientific objectives of
cosmological focus: to probe the expansion rate of the universe, and to understand …

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 …

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 …

We undertake a careful analysis of stochastic gravitational wave production from
cosmological phase transitions in an expanding universe, studying both a standard radiation …

Detection of a gravitational-wave signal of non-astrophysical origin would be a landmark
discovery, potentially providing a significant clue to some of our most basic, big-picture …

We derive efficiency factors for the production of gravitational waves through bubble
collisions and plasma-related sources in strong phase transitions, and find the conditions …

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 …
