Description
One of the landmarks guiding our understanding of physical cosmology is the large-scale structure, defined as the large scale distributions of galaxies, as observed by galaxy surveys. In this context, the so-called Baryon Acoustic Oscillations, are considered one of the most powerful cosmological probes. They are generally deemed to provide distance measures independent of a specific cosmological model. At the same time the obtained distances are considered agnostic with respect to other cosmological observations. However current measurements are obtained relying on several fitting and model prescriptions.
Does this comply with the requirement of model and parameter independent cosmological distances useful, for instance, to select cosmological models, detect Dark Energy and characterize cosmological tensions?
In this talk I will review the subject, answer compelling questions and explore new promising research directions.
