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 …

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 …

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 …

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 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 …

Electroweak baryogenesis (EWBG) remains a theoretically attractive and experimentally
testable scenario for explaining the cosmic baryon asymmetry. We review recent progress in …

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