ABSTRACT

We develop an efficient methodology to extract the tomographic BAO information from galaxy survey based on the optimal redshift weighting scheme, and perform anisotropic BAO measurements in Fourier space using the eBOSS DR14 quasar catalog. We reconstruct the evolution history of the BAO distance indicators in the redshift range of 0.8 less than z less than 2.2 and improve the constraint on the BAO dilation parameter \alpha(z_{eff}).
