Top: Location of galaxies in a ﹩30\times 30\times 100﹩ proper Mpc (equivalent to cosmic time along the line of sight) region of the J0053+1234 field chosen to include three distinct redshift features near ﹩z=0.43﹩ in Table 2. The faint "ribs" connecting individual galaxies to the central "spine" (chosen to lie at the center of the main field) are perpendicular to the spine. Our typical velocity error of 200 km s﹩^{-1}﹩ Mpc﹩^{-1}﹩ corresponds to a distance of 2.4 Mpc along the line of sight, and departures from Hubble expansion are less than ~7 Mpc. The radius of a galaxy symbol corresponds to ﹩M^{*}_{R}-M_{R}﹩. The galaxies are color‐coded: red: absorption‐line galaxies; green: composite galaxies; blue: emission‐line galaxies. Note that absorption‐line galaxies are more luminous and concentrated in the redshift features. It is apparent that galaxies are clustered around this concentration with correlation lengths of ~20–30 proper Mpc. The three principal features are roughly colinear, but in general there is little indication that galaxies are arranged on either planes or lines. Bottom: A more typical region, with similar dimensions, displaced from that shown in the top panel by ﹩\Delta z=0.1﹩.
