Large-Scale Structure Formation & Simulations: Structures & Vocabulary

Large-scale structure forms when small primordial density fluctuations grow through gravity in an expanding universe. Cosmological simulations interpret surveys, predict observables, connect galaxies to dark halos, and test dark matter and dark energy models.
