Cosmological implications of baryon acoustic oscillation measurements

“…However, this geometric degeneracy is broken when combining all three sets of data. We then obtain the value H 0 = (68.8 ± 1.2)km/s/Mpc, which is in good agreement with current constraints [5,130,141]. Our value is slightly but not significantly larger, which can be understood as an artifact of using the distance priors [129].…”

“…For ΛCDM, Planck collaboration obtains the value H 0 = 67.4 ± 0.5 km s −1 Mpc −1 [53]. Our calculations with zero or negligible SNIa evolution agree quite well with the Planck results and therefore are able to replicate a similar behaviour as the standard model, without having Λ. Additionally, our results are in agreement with the results given by BOSS Collaboration [54] as H 0 = 67.3 ± 1.1 using a cosmic microwave background calibrated distance scale of BAO and SNIa measurements, and the model independent estimate of Haridasu et al [55] H 0 = 68.52 +3.45 −0.94 km s −1 Mpc −1 , which has been obtained using Multi-Task Gaussian Process and by considering the data of SNIa, BAO, and cosmic chronometers.…”

“…We find that our best-fit parameters are consistent with previous analyses. For example, we find M 1 B = −19.12 ± 0.03 mag (68% confidence) which is consistent with the value from Aubourg et al (2015) of M 1 B = −19.14 ± 0.042 mag. Moreover, Figure 2 illustrates that, as expected, SNe Ia alone are unable to constrain this parameter, given the strong correlation with H 0 (also seen in the figure).…”
