Interactive Cosmological Power Spectra


See how the matter power spectrum and the angular power spectrum of the cosmic microwave background change as a function of cosmological parameters. We have assumed a flat universe with Ωm + ΩΛ = 1. We use Planck 2015 results as a fiducial cosmology. All computations performed using CAMB.
