| 英文摘要 | Even though the Hubble constant cannot be significantly determined just by the low-redshift Baryon Acoustic Oscillation (BAO) data, it can be tightly constrained once the high-redshift BAO data are combined. We combined BAO data from 6dFGS, BOSS DR11 clustering of galaxies, WiggleZ and z = 2.34 from BOSS DR11 quasar Lyman-alpha forest lines to get H-0 = 68.17(-1.56)(+1.55) s(-1) Mpc(-1). In addition, we adopted the simultaneous measurements of H(z) and DA(z) from the two-dimensional two-point correlation function from BOSS DR9 CMASS sample and two-dimensional matter power spectrum from SDSS DR7 sample to obtain H-0 = (68.11 +/- 1.69) km s(-1) Mpc(-1). Finally, combining all of the BAO datasets, we conclude that H0 = (68.11 +/- 0.86) km s(-1) Mpc(-1), a 1.3% determination. |
