论文摘要
我们介绍了Sloan Digital Sky Survey IV数据释放16（DR16）的扩展Baryon振荡光谱调查（EBOSS）的发射线星系（ELG）样品。在描述了在1170度$^2 $上观察到的269,243观察到的ELG光谱的观测和红移测量之后，我们介绍了用于宇宙学分析的大规模结构目录。这些目录包含173,736个可靠的光谱红移在0.6到1.1之间，以及量化观测程度的相关随机目录，以及适当的权重以纠正非颜色波动。我们在配置空间中执行球形平均的巴属声学振荡（BAO）测量，并具有密度字段重建：数据2点相关函数显示了与BAO的特征，提供了3.2％的球形测量值，从而提供了3.2％的bao d_v（z _ v fragimand trail $ d_v（z _） = 18.23 \ pm 0.58 $在有效的红移$ z _ {\ rm eff} = 0.845 $。
We present the Emission Line Galaxy (ELG) sample of the extended Baryon Oscillation Spectroscopic Survey (eBOSS) from the Sloan Digital Sky Survey IV Data Release 16 (DR16). After describing the observations and redshift measurement for the 269,243 observed ELG spectra over 1170 deg$^2$, we present the large-scale structure catalogues, which are used for the cosmological analysis. These catalogues contain 173,736 reliable spectroscopic redshifts between 0.6 and 1.1, along with the associated random catalogues quantifying the extent of observations, and the appropriate weights to correct for non-cosmological fluctuations. We perform a spherically averaged baryon acoustic oscillations (BAO) measurement in configuration space, with density field reconstruction: the data 2-point correlation function shows a feature consistent with that of the BAO, providing a 3.2-percent measurement of the spherically averaged BAO distance $D_V(z_{\rm eff})/r_{\rm drag} = 18.23\pm 0.58$ at the effective redshift $z_{\rm eff}=0.845$.
