Gravitational Waves Created During the EWPT

TL;DR

This paper investigates the generation of gravitational waves during the Electroweak Phase Transition, focusing on the magnetic fields produced by bubble collisions and their role in emitting gravitational radiation shortly after the Big Bang.

Contribution

It introduces a model linking magnetic fields from bubble collisions during the EWPT to gravitational wave production, highlighting a new mechanism for early universe gravitational radiation.

Findings

Magnetic fields from bubble collisions can generate detectable gravitational waves.

The timing of the EWPT (~10^{-11} seconds after Big Bang) is crucial for gravitational wave signals.

The study provides estimates for the energy radiated as gravitational waves during the EWPT.

Abstract

We study gravitational waves generated by bubble expansion created during the Cosmological Electroweak Phase Transition (EWPT). The energy radiated via gravitational waves is produced by the stress-energy tensor created by the magnetic field produced by bubble collisions during the EWPT, which occured about $10{-11}$ seconds after the Big Bang.
