On accretion mechanism of large-scale structure generation in the Universe

A formation scenario for stringlike large-scale structure of the Universe is discussed. The main physical mechanism is the matter accretion into the wake of a rapidly moving massive body. The previously formed galaxy clusters and almost symmetric loops are considered as such bodies in the cases of the entropy model and the cosmic strings model respectively. Estimates indicate that, due to developing gravitational instability, the wake of the loop breaks into blobs with masses approaching those of the galaxies. Long-wave perturbations can cause the formation of protoclusters from these blobs of matter
