摘要:
Thorough numerical calculations of the fluctuations in the cosmic microwave background radiation using the gauge-invariant formalism are carried out for various cosmological models with the cosmological constant. It is shown that a spatially flat cold dark matter-dominated universe of Ω0 = 0.1 ∼ 0.4 and H0 = 50 ∼ 100 km s-1 Mpc-1 with adiabatic perturbations has the possibility of giving the final answer to cosmological puzzles. It is also found that the introduction of the cosmological constant may revive pure baryonic universe models.
