The clustering of the SDSS-IV extended Baryon Oscillation Spectroscopic Survey DR14 quasar sample : anisotropic Baryon Acoustic Oscillations measurements in Fourier-space with optimal redshift weights
MetadataShow full item record
We present a measurement of the anisotropic and isotropic Baryon Acoustic Oscillations (BAO) from the extended Baryon Oscillation Spectroscopic Survey Data Release 14 quasar sample with optimal redshift weights. Applying the redshift weights improves the constraint on the BAO dilation parameter α(zeff) by 17%. We reconstruct the evolution history of the BAO distance indicators in the redshift rangeof 0.8 < z < 2.2. This paper is part of a set that analyses the eBOSS DR14 quasar sample.
