Statistical characteristics of a stochastic background of gravitational waves from neutron star formation

By using a recent model for the evolving star formation rate, we investigate the statistical distribution of gravitational wave amplitudes due to supernovae that result in neutron star formation in the Einstein-de Sitter cosmiology. To account for the uncertainty in gravitational wave emission for this source type, we use a random mixture of three simulated waveform types computed by Zwerger and Muller. We investigate statistical parameters of the resulting gravitational wave amplitude distribution in our frame.
