Distribution of galaxies within an R = 175 h−1 Mpc cylinder from DESI DR1 (top left), and in five nonoverlapping geometry-matched cylinders selected from FLAMINGO at z = 0.15. The extent of the region approximates the true extent of the S2 data. In the top row, the right five panels show FLAMINGO galaxies including redshift-space distortions. The middle row shows FLAMINGO galaxies in real space without redshift-space distortions. The bottom row shows the FLAMINGO density field sampled by dark-matter particles. Also at this scale, the amount of structure in DESI DR1 is visually similar to that in FLAMINGO galaxy catalogs with redshift-space distortions included. Without redshift-space distortions, the clustering is weaker, and the clustering in the particle distribution is the weakest.
