Baryon Acoustic Oscillations (BAO) are frozen relics left over from the pre-decoupling universe. They are the standard rulers of choice for 21st century cosmology, providing distance estimates that are, for the first time, firmly rooted in well-understood, linear physics. This review synthesises current understanding regarding all aspects of BAO cosmology, from the theoretical and statistical to the observational, and includes a map of the future landscape of BAO surveys, both spectroscopic and photometric.

As the baryons accumulated in the potential wells, their pressure would have built up, leading to oscillations in the baryon fluid, termed “baryon acoustic oscillations” (BAO) [240,241]. These oscillations leave an imprint on the CMB power spectrum, which has been confirmed ob”
