论文摘要
我们提出了2000个模拟星系目录，用于分析在扩展的BARYON振荡光谱调查数据释放16（Eboss DR16）的发射线星系（ELG）样品中的重子震荡。每个模拟目录的数字密度为$ 6.7 \ times 10^{ - 4} h^3 \ rm mpc^{ - 3} $，覆盖红移范围为0.6至1.1。这些模拟是在10 $ h^{ - 1} $ mpc的尺度上校准的小规模EBOSS ELG聚类测量值。模拟目录是使用星系模拟（GLAM）模拟和快速粒子网（QPM）方法的组合生成的。 GLAM模拟用于生成密度场，然后使用QPM方法分配了暗物质光晕。使用光环占用分布（HOD）填充了星系。结果模拟与数据的几何形状和选择功能相匹配，并且数量密度略高，这允许系统分析的空间。 Baryon声学振荡（BAO）量表的模拟大规模聚类与数据一致，我们介绍了模拟的相关矩阵。
We present 2000 mock galaxy catalogs for the analysis of baryon acoustic oscillations in the Emission Line Galaxy (ELG) sample of the Extended Baryon Oscillation Spectroscopic Survey Data Release 16 (eBOSS DR16). Each mock catalog has a number density of $6.7 \times 10^{-4} h^3 \rm Mpc^{-3}$, covering a redshift range from 0.6 to 1.1. The mocks are calibrated to small-scale eBOSS ELG clustering measurements at scales of around 10 $h^{-1}$Mpc. The mock catalogs are generated using a combination of GaLAxy Mocks (GLAM) simulations and the Quick Particle-Mesh (QPM) method. GLAM simulations are used to generate the density field, which is then assigned dark matter halos using the QPM method. Halos are populated with galaxies using a halo occupation distribution (HOD). The resulting mocks match the survey geometry and selection function of the data, and have slightly higher number density which allows room for systematic analysis. The large-scale clustering of mocks at the baryon acoustic oscillation (BAO) scale is consistent with data and we present the correlation matrix of the mocks.
