BAO as a Standard Ruler in Cosmology

Friedmann-Lemaître-Robertson-Walker (FLRW) Cosmology → Survey Data Analysis and Systematics

This advanced graduate-level learning path covers the physics of Baryon Acoustic Oscillations (BAO) from the sound horizon in the early universe to their use as a standard ruler for probing dark energy. It builds from cosmological perturbation theory and large-scale structure through observational techniques in galaxy surveys and the Lyman-alpha forest, culminating in dark energy constraints.
