The ∼5σ mismatch between the Hubble parameter measured by SH0ES and the value inferred from the inverse distance ladder (IDL) currently
represents the most significant tension within the Standard Model of Cosmology. In this talk, I will discuss the late-time phenomenology required to solve the Hubble crisis if standard physics before recombination is assumed, particularly emphasizing the crucial role played by baryon acoustic oscillations (BAO) data, employed to build the IDL. I will show that angular (2D) and anisotropic (3D) BAO data, despite being extracted from the same parent catalogues of tracers, leave an imprint on completely different scales and might have a distinct impact on the perturbed observables at play. With the aid of Supernovae of type Ia (SNIa), I will illustrate how this discrepancy can be reframed in terms of a BAO tension through a largely model-independent approach, and how the results change when the angular components of the 3D BAO data from BOSS/eBOSS are substituted by the recent data from DESI Y1. The tension is found to be at the level of ∼2𝜎 and ∼2.5𝜎, respectively, when the SNIa of the Pantheon+ compilation are used, and at ∼4.6𝜎 when the latter are replaced with those of DESY5. In view of these results, I will finally discuss a calibrator-independent method to assess the robustness of the distance duality relation.
