Matter power spectrum in alternative models compared to the CDM scenario in the dark (left) and FP (middle and right) runs at z = 0. For each dark matter model, we plot the ratio to the CDM value in the range 1 h Mpc⁻¹≤k≤300 h Mpc⁻¹, corresponding to scales 1 h⁻¹Mpc≥l≥0.003 h⁻¹Mpc. At scales larger than 1 h⁻¹Mpc, the power spectra are identical, indicating that the large-scale structure distribution is unaltered by ADM effects. Each dark matter model is represented by a different colour, while the thin (thick) lines show the results for the 50 (100) Mpc boxes.
