要旨

We describe the results of high-resolution numerical simulations of string-induced structure formation in open universes and those with a nonzero cosmological constant. For models with Γ = Ωh = 0.1–0.2 and a cold dark matter background, we show that the linear density fluctuation power spectrum has both an amplitude at 8h-1 Mpc, σ8, and an overall shape which are consistent within uncertainties with those currently inferred from galaxy surveys. The cosmic string scenario with hot dark matter requires a strongly scale-dependent bias in order to agree with observations.
