N-cluster Run : Cosmological N-body simulation for statistical study on galaxy cluster and cosmic web

<Cluster+Group catalog> <Satellite catalog> <Cosmic Web catalog>

We performed 64 different cosmological N-body simulations whose one side length is 120 Mpc/h with particle mass of ~109 Msun/h.
Each box can be used for zoom simulations with high-resolution elements (N-body and/or hydro) to resolve more detailed dynamics/hydrodynamics on interested regions.
These simulation data can be used for studying various properties of galaxy cluster respect to large-scale structures.
