Circular polarization of gravitational waves from early-Universe helical turbulence

Circular polarization of gravitational waves from early-Universe helical turbulence

We perform direct numerical simulations to compute the net circular polarization of gravitational waves from helical (chiral) turbulent sources in the early Universe for a variety of initial conditions, including driven (stationary) and decaying turbulence. We investigate the resulting gravitational...
