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 …

TianQin is a planned space-based gravitational wave (GW) observatory consisting of three
Earth-orbiting satellites with an orbital radius of about. The satellites will form an equilateral …

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

A bstract Gravitational waves (GWs) from strong first-order phase transitions (SFOPTs) in the
early Universe are a prime target for upcoming GW experiments. In this paper, I construct …

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 …

The terminal wall velocity of a first-order phase transition bubble in the early Universe can
be calculated from a set of fluid equations describing the scalar fields and the plasma's state …

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 …

Inspired by the recent evidences of nano-Hertz stochastic gravitational waves observed by
the pulsar timing array collaborations, we explore their implied supercooled electroweak …

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 …
