Overview
Advanced view of Large-Scale Structure Formation & Simulations
Large-scale structure forms when small primordial density fluctuations grow through gravity in an expanding universe. Numerical simulations follow billions of particles and fluid elements to test whether assumed cosmology and matter content can reproduce the observed cosmic web.
Cosmological simulations interpret surveys, predict observables, connect galaxies to dark halos, and test dark matter and dark energy models.
