About this dataset
SCIDAC 128 SG5 (Gravity Only) is the single gravity-only realization paired with the 64 hydrodynamic members of the SCIDAC 128 SG5 Phase-1 suite. It evolves 5123 gravity particles in the same 128 Mpc/h box from their common initial-condition realization.
Because every hydrodynamic member shares this realization, the dataset supplies a common gravity-driven baseline for direct measurements of baryonic suppression and other subgrid-model effects. The portal exposes snapshot halo catalogs, spherical-overdensity profiles, and halo particles at z = 0, 0.1, 0.5, 1, and 2.
