We perform simulations in a simple model that aims to mimic the hydrodynamic evolution of a relativistic fluid during a cosmological first-order phase transitions. The observable we are concerned with is hereby the spectrum of gravitational radiation produced by colliding fluid shells. We present simple parameterizations of our results as functions of the wall velocity, the duration of the phase transition and the latent heat. We also improve on previous results in the envelope approximation…

Model-independent features of gravitational waves from bubble collisions

We study the gravitational radiation produced by the collisions of bubble walls or thin fluid shells in cosmological phase transitions. Using the so-called envelope approximation, we obtain

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 of

Gravitational waves from first-order phase transitions: ultra-supercooled transitions and the fate of relativistic shocks

We study the gravitational wave (GW) production in extremely strong first order phase transitions where the vacuum energy density dominates the plasma energy density, α ≳ 1. In such transitions,

A hybrid simulation of gravitational wave production in first-order phase transitions

The LISA telescope will provide the first opportunity to probe the scenario of a first-order phase transition happening close to the electroweak scale. In thermal transitions, the main contribution

Relativistic bubble collisions—a closer look

We study scalar bubble collisions in first-order phase transitions focusing on the relativistic limit. We propose `trapping equation' which describes the wall behavior after collision, and test it

Higgsless simulations of cosmological phase transitions and gravitational waves

First-order cosmological phase transitions in the early Universe source sound waves and, subsequently, a background of stochastic gravitational waves. Currently, predictions of these gravitational

Updated predictions for gravitational waves produced in a strongly supercooled phase transition

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 ∝ γ2 scaling of the

Generation of gravitational waves from freely decaying turbulence

We study the stochastic gravitational wave background (SGWB) produced by freely decaying vortical turbulence in the early Universe. We thoroughly investigate the time correlation of the velocity



Gravitational waves from the sound of a first order phase transition.

It is found that the compression waves in the fluid continue to be a source of GWs long after the bubbles have merged, a new effect not taken properly into account in previous modeling of the GW source.

Numerical simulations of acoustically generated gravitational waves at a first order phase transition

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 of

Revisiting the envelope approximation: Gravitational waves from bubble collisions

We study the envelope approximation and its applicability to first-order phase transitions in the early universe. We demonstrate that the power laws seen in previous studies exist independently of

General properties of the gravitational wave spectrum from phase transitions

In this paper we discuss some general aspects of the gravitational wave background arising from postinflationary short-lasting cosmological events such as phase transitions. We concentrate on the

Gravitational waves from bubble dynamics: beyond the envelope

We study gravitational-wave production from bubble dynamics (bubble collisions and sound waves) during a cosmic first-order phase transition with an analytic approach. We first propose modeling the

Gravitational wave generation from bubble collisions in first-order phase transitions: An analytic approach

Gravitational wave production from bubble collisions was calculated in the early nineties using numerical simulations. In this paper, we present an alternative analytic estimate, relying on a

Gravitational wave production by collisions: more bubbles

We re-examine the production of gravitational waves by bubble collisions during a first-order phase transition. The spectrum of the gravitational radiation is determined by numerical simulations

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

Gravitational-Wave Constraints on the Neutron-Star-Matter Equation of State.

It is concluded that the maximal radius of a 1.4-solar-mass neutron star is 13.6 km, and that the smallest allowed tidal deformability of a similar-mass star is Λ(1.4  M_{⊙})=120.4%.

Gravitational radiation from colliding vacuum bubbles: Envelope approximation to many-bubble collisions.

We introduce an approximation to calculate the gravitational radiation produced by the collision of true-vacuum bubbles that is simple enough to allow the simulation of a phase transition by the
