Cosmic Microwave Background (CMB) Anisotropy Simulator

Cosmology: CMB Power Spectrum & Primordial Noise

CMB Anisotropy

Acoustic Peaks & Cosmic Geometry

Tweak the composition of the early universe. Watch how changing the baryon, dark matter, and dark energy densities shifts the acoustic peaks of baryon oscillations and filters the primordial sky map.

Baryon Density (Ωb): 0.05

Cold Dark Matter (Ωc): 0.25

Dark Energy (Ωλ): 0.70
