Gravitational Radiation from Primordial Helical Turbulence
Abstract
Description
In present talk I show that primordial helical turbulence produced during a first-order phase transition induces circularly polarized cosmological gravitational waves (GWs). The degree of polarization as well as the characteristic frequency and the amplitude of these GWs depend crucially on phase-transition model of primordial turbulence. I present a brief discussion on the possibility of detection.
