The effect of extra dimensions on gravity wave bursts from cosmic string cusps

Year: 2010

Type: article

Abstract: We explore the kinematical effect of having extra dimensions on the gravitational wave emission from cosmic strings. Additional dimensions both round off cusps, and reduce the probability of their formation. We recompute the gravitational wave burst, taking into account these two factors, and find a potentially significant damping on the gravitational waves of the strings.
