Spatial distribution of simulated galaxies in the Fornax-like system present in IllustrisTNG-50. Left: Distribution of galaxies up to 1R₂₀₀ (continuous cyan line) and 3R₂₀₀ (dashed black line). Late, early, and nonemitter galaxies bound to the cluster are shown in squares (blue), triangles (red), and full circles (maroon), respectively. Additionally, gray dots show galaxies within 5R₂₀₀ of the cluster that are not gravitationally bound to the cluster. Right: Zoom region showing the galaxy distribution within 1R₂₀₀ of the Fornax-like system.
