A measurement of the Hubble constant using galaxy redshift surveys
  We perform a measurement of the Hubble constant, $H_0$, using the latest
baryonic acoustic oscillations (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 (KL)
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.
