WebNov 29, 2024 · Abstract: Baryon Acoustic Oscillations are a phenomenon occurred before matter-radiation decoupling, characterized because the baryonic matter perturbation presents oscillations, as the name suggests. These perturbations propagate like a pressure wave on the photon-baryon fluid produced by gravitational potentials, which join the …
