Structure
Structure of Large-Scale Structure Formation & Simulations
Simulations represent dark matter gravitationally and may include gas hydrodynamics, cooling, star formation, black-hole growth, chemical enrichment, and feedback. Initial conditions are drawn from a primordial fluctuation spectrum constrained by the cosmic microwave background.
