A robust standard rod for cosmology

Abstract: Baryon Acoustic Oscillations provide a standard rod for constraining cosmological distances and the expansion history of our universe over a substantial fraction of its history. I will review the physics which motivates this standard rod and summarize constraints from its use. Finally, I will discuss ways of making the rod more robust so that it can more easily be used to constrain non-standard cosmological models. This is particularly important given recent tension between local and distant estimates of the Hubble constant.
