Spatial distribution of central galaxies at z = 0 within a simulation box slice spanning 100 Mpc h⁻¹ < z < 150 Mpc h⁻¹. The color of each point represents D₅, the distance to the fifth nearest bright neighbor, normalized by the mean value of the complete snapshot, which serves as a proxy for the local galaxy density. Left panel: Area of 1000 Mpc h⁻¹ per side. Right panel: Zoomed-in view of the highlighted region.
