Mixed Cold-Hot Dark Matter Model with Falling and Quasi-Flat Initial Perturbation Spectra

The mixed cold-hot dark matter cosmological model (CHDM) with Omega(tot) = 1 and a falling power-law initial spectrum of Gaussian adiabatic perturbations (n > 1) is tested using recent observational data. It is shown that its fit to the data becomes worse with the growth of n - 1 and may be considered as unreasonable for n > 1.1 for all p...更多
