AbstractWe test the mutual consistency between the baryon acoustic oscillation measurements from the eBOSS SDSS final release and the Pantheon supernova compilation in a model-independent fashion using Gaussian process regression. We also test their joint consistency with the ?CDM model in a model-independent fashion. We also use Gaussian process regression to reconstruct the expansion history that is preferred by these two data sets. While this methodology finds no significant preference for model flexibility beyond ?CDM, we are able to generate a number of reconstructed expansion histories that fit the data better than the best-fit ?CDM model. These example expansion histories may point the way toward modifications to ?CDM. We also constrain the parameters omega(k) and H(0)r(d) both with ?CDM and with Gaussian process regression. We find that H(0)r(d) = 10,030 130 km s(-1) and omega(k) = 0.05 0.10 for ?CDM and that H(0)r(d) = 10,040 140 km s(-1) and omega(k) = 0.02 0.20 for the Gaussian process case.
