June 9, 11am – 12 pm: Stefano Anselmi (University of Padova, Italy)

Are Baryonic Acoustic Oscillations a Dark Energy Probe?

Baryon Acoustic Oscillations are considered one of the most powerful Dark Energy cosmological probes. They are assumed to provide distance measures independent of a specific cosmological model. However, in current measurements, the inference is done assuming parameter values of a fiducial LCDM model and employing prescriptions tested to be unbiased only within some LCDM fiducial cosmologies. Moreover the procedure is plagued by the ambiguity of choosing a specific correlation function model-template to measure cosmological distances. Does this comply with the requirement of model-independent distances useful, for instance, to select cosmological models or characterize tensions? In this talk I will review the subject, answer to compelling questions and explore new promising research directions.
