We undertake a careful analysis of stochastic gravitational wave production from cosmological phase transitions in an expanding universe, studying both a standard radiation as well as a matter dominated history. We analyze in detail the dynamics of the phase transition, including the false vacuum fraction, bubble lifetime distribution, bubble number density, mean bubble separation, etc., for an expanding universe. We also study the full set of differential equations governing the evolution of… Expand
Gravitational tests of electroweak relaxation
Abstract We consider a scenario in which the electroweak scale is stabilized via the relaxion mechanism during inflation, focussing on the case in which the back-reaction potential is generated byExpand
Gravitational waves from a holographic phase transition
We investigate first order phase transitions in a holographic setting of five-dimensional Einstein gravity coupled to a scalar field, constructing phase diagrams of the dual field theory at finiteExpand
Baryogenesis and gravity waves from a UV-completed electroweak phase transition

Di-Higgs blind spots in gravitational wave signals
Conditions for strong first-order phase transition and generation of observable gravitational wave (GW) signals are very restrictive to the profile of the Higgs potential. Working in the minimalExpand
Electroweak phase transition in an inert complex triplet model
We study the dynamics of electroweak phase transition in a simple extension of the Standard Model where the Higgs sector is extended by adding an $SU(2)_L$-triplet with hypercharge Y=2. By makingExpand
Electroweak phase transition with an SU(2) dark sector
Abstract We consider a non-Abelian dark SU(2)D model where the dark sector couples to the Standard Model (SM) through a Higgs portal. We investigate two different scenarios of the dark sectorExpand
Exploring the Early Universe with Gaia and THEIA
It has recently been pointed out that Gaia is capable of detecting a stochastic gravitational wave background in the sensitivity band between the frequency of pulsar timing arrays and LISA. We argueExpand
Gravitational waves from bubble walls
We present a general method for computing the gravitational radiation arising from the motion of bubble walls or thin fluid shells in cosmological phase transitions. We discuss the application ofExpand
Gravitational waves from first-order phase transitions in Majoron models of neutrino mass
We show how the generation of right-handed neutrino masses in Majoron models may be associated with a first-order phase transition and accompanied by the production of a stochastic background ofExpand


Sound Shell Model for Acoustic Gravitational Wave Production at a First-Order Phase Transition in the Early Universe.
The detailed dependence of the power spectrum on the wall speed and the other parameters of the phase transition raises the possibility of their constraint or measurement at a future space-based gravitational wave observatory such as LISA. Expand
Shape of the acoustic gravitational wave power spectrum from a first order phase transition
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 wave and theExpand

We present details of numerical simulations of the gravitational radiation produced by a first order thermal phase transition in the early universe. We confirm that the dominant source ofExpand
On the maximal strength of a first-order electroweak phase transition and its gravitational wave signal
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 could increaseExpand

The production of gravitational waves by an electroweak first-order phase transition is reviewed and a good candidate for detection at next-generation gravitational wave detectors, such as LISA, is reviewed. Expand
The First Three Seconds: a Review of Possible Expansion Histories of the Early Universe
It is commonly assumed that the energy density of the Universe was dominated by radiation between reheating after inflation and the onset of matter domination 54,000 years later. While the abundanceExpand

Gravitational Imprints of Flavor Hierarchies.
It is pointed out that the observation of a multipeaked stochastic gravitational wave signal from a series of cosmological phase transitions could well be a unique probe of the mechanism behind flavor hierarchies. Expand
