Abstract

We show that helical turbulence produced during a first-order phase transition generates circularly polarized cosmological gravitational waves (GWs). The characteristic frequency of these GWs for an extreme case of the phase transition model is around 10-3-10-2Hz with an energy density parameter as high as 10-12-10-11. The possibility of detection is briefly discussed.
