This analysis reveals the source of scalar-induced gravitational waves in perturbation peaks, indicating new insights into cosmological phenomena.
We offer a physical interpretation of the origin of the scalar-induced gravitational wave background, showing that it is mainly produced around the peaks of the scalar perturbations. We also provide a compact expression to estimate the amount of scalar-induced gravitational waves generated by peaks.
