Three-dimensional visualization of the five cosmic environments used in our analysis: galaxy clusters (red), cluster outskirts (blue), filaments (yellow), filaments outskirts (brown). Groups are shown as transparent magenta spheres, with radii equal to 3 times the R₂₀₀ of each halo. Galaxies classified as filaments lie within 1 h⁻¹ Mpc of the filament axis, while those in filament outskirts lie between 1 and 2 h⁻¹ Mpc. This figure was generated using our SDSS DR18 dataset and environment classification scheme.
