星系两点相关函数中的重子声学振荡（BAO）特征为探索宇宙膨胀历史提供了一个标准标尺。本文研究了几种星系选择方案，旨在建立红移范围为0.6 - 1.5的发射在线星系（ELG）样本，但受当前数据集深度的限制，无法获得精确的星系偏差值。使用这种质量场示踪剂的调查将保证BAO的高意义检测。
The baryon acoustic oscillation (BAO) feature in the two-point correlation function of galaxies supplies a standard ruler to probe the expansion history of the Universe. We study here several galaxy selection schemes, aiming at building an emission-line galaxy (ELG) sample in the redshift range 0.6 1.5), but we are limited by current data sets depth to derive precise values of the galaxy bias. A survey using such tracers of the mass field will guarantee a high significance detection of the BAO.
