摘要：
We study the process of superdense dark matter clump (DMC) formation at the radiation-dominated stage of the Universe. High-magnitude density perturbations that lead to DMC formation can be peaks in the inflationary perturbation spectrum or closed loops of cosmic strings. A model with superdense DMCs provides new opportunities for annihilation of particles having small annihilation cross-sections. Superdense DMCs can be detected by their tidal effect on gravitational wave detectors.
