英文摘要 | We perform a measurement of the Hubble constant, H-0, using the latest baryonic acoustic oscillation (BAO) measurements from galaxy surveys of 6dFGS, SDSS DR7 Main Galaxy Sample, BOSS DR12 sample, and eBOSS DR14 quasar sample, in the framework of a flat Lambda CDM model. Based on the Kullback-Leibler divergence, we examine the consistency of H-0 values derived from various data sets. We find that our measurement is consistent with that derived from Planck and with the local measurement of H-0 using the Cepheids and type Ia supernovae. We perform forecasts on H-0 from future BAO measurements, and find that the uncertainty of H-0 determined by future BAO data alone, including complete eBOSS, DESI, and Euclid-like, is comparable with that from local measurements. |
