M_DM, 1/2/M_⋆, 1/2 plotted against M_⋆ for the CAMELS simulations. Each row shows variations in the cosmological parameters Ω_m and σ₈. The green lines represent the reference CAMELS simulation. To examine the evolution across redshift, simulation snapshots at z = 0, z = 0.5, z = 1, z = 1.5, and z = 2 are displayed from left to right. The medians in stellar mass bins are shown. For the reference simulation the 16-84th percentile range is also shown as a shaded green region.
