@article{Cuceu2019BaryonAO, title={Baryon Acoustic Oscillations and the Hubble constant: past, present and future}, author={Andrei Cuceu and James Farr and Pablo Lemos and Andreu Font-Ribera}, journal={Journal of Cosmology and Astroparticle Physics}, year={2019}, volume={2019}, pages={044 - 044} }

We investigate constraints on the Hubble constant (H0) using Baryon Acoustic Oscillations (BAO) and baryon density measurements from Big Bang Nucleosynthesis (BBN). We start by investigating the tension between galaxy BAO measurements and those using the Lyman-α forest, within a Bayesian framework. Using the latest results from eBOSS DR14 we find that the probability of this tension being statistical is ≃6.3% assuming flat ΛCDM. We measure H0 = 67.6±1.1 km s−1 Mpc−1, with a weak dependence on…
