COSMOLOGICAL EXPLOSIONS FROM COLD DARK MATTER PERTURBATIONS

We examine the cosmological explosion model in a universe dominated by cold dark matter in which explosion seeds are produced from the growth of initial density perturbations of the form delta-rho/rho = (M/M0)-n. Fragmentation of the exploding shells is dominated by the dark matter potential wells rather than the self-gravity of the shells, and n < 0.36 is required for the explosions to bootstrap up to very large scales. The final distribution of dark matter is strongly correlated with the baryons on small scales, but uncorrelated on large scales.
