Baryon acoustic oscillations at z = 2.34 from the correlations of Ly α absorption in eBOSS DR14
Abstract
We measure the imprint of primordial baryon acoustic oscillations (BAOs) in the correlation function of Ly αabsorption in quasar spectra from the Baryon Oscillation Spectroscopic Survey (BOSS) and the extended BOSS (eBOSS) in Data Release 14 (DR14) of the Sloan Digital Sky Survey (SDSS)-IV. In addition to 179 965 spectra with absorption in the Lyman- α(Ly α) region, we use Ly αabsorption in the Lyman- βregion of 56 154 spectra for the first time. We measure the Hubble distance, D H, and the comoving angular diameter distance, D M, relative to the sound horizon at the drag epoch r dat an effective redshift z = 2.34. Using a physical model of the correlation function outside the BAO peak, we find D H(2.34)/ r d = 8.86 ± 0.29 and D M(2.34)/ r d = 37.41 ± 1.86, within 1 σfrom the flat-ΛCDM model consistent with CMB anisotropy measurements. With the addition of polynomial “broadband” terms, the results remain within one standard deviation of the CMB-inspired model. Combined with the quasar-Ly αcross-correlation measurement presented in a companion paper, the BAO measurements at z = 2.35 are within 1.7 σof the predictions of this model.
