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 …

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 …

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

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 propose a space-based interferometer surveying the gravitational wave (GW) sky in the
milli-Hz to μ-Hz frequency range. By the 2040s, the μ-Hz frequency band, bracketed in …

We explore gravitational wave signals arising from first-order phase transitions occurring in
a secluded hidden sector, allowing for the possibility that the hidden sector may have a …

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 investigate the potential for the eLISA space-based interferometer to detect the
stochastic gravitational wave background produced by strong first-order cosmological phase …

We analyze Higgs condensate bubble expansion during a first-order electroweak phase
transition in the early Universe. The interaction of particles with the bubble wall can be …

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 …
