About this dataset
The EDENS EDE (Gravity Only) is a medium-size simulation evolved from an early dark energy (EDE) cosmology. Early dark energy increases the expansion rate of the universe prior to recombination, and is a possible solution to the Hubble Tension. This simulation evolves 20483 gravity particles in a 1200 Mpc = 866.28 Mpc / h survey volume, making it a good dataset for examining the effects of EDE on large-scale structure.
Snapshot halo catalogs, spherical-overdensity profiles, and halo particles are available at z = 0, 0.1, 0.5, 1, and 2
