Abstract

Understanding the development of the very early stages of the Big Bang is tightly linked to the understanding of the fundamental nature of matter and interactions. With the Large Hadron Collider delineating the nature of the Higgs, we have the opportunity to make predictions using the new knowledge, enabling a sharper picture of the very early universe.

In this project we will use state-of-the art high performance computing to calculate the gravitational wave signal from a phase transition in the Higgs field in at around a tenth of a nanosecond after the Big Band, including the hydrodynamics of the hot plasma. This radiation may be observable in planned space-based gravitational wave detectors such as eLISA.
