Left: sky positions of the galaxies in the GOODS-South field with H< 23. The colors indicates the redshift: blue points are z< 0.3, red points are z> 1.5, and galaxies in between are shown in shades of purple. Middle: angular two-point correlation function for GOODS-South galaxies with 9 < log ₁₀(M_∗/M_⊙) < 10.3, in various redshift slices as indicated in the legend. The straight black line is a power law of index − 1. Error bars are not shown for clarity. Right: same as left, but for the mock catalog produced by EGG.
