Large-scale structure forms when small primordial density fluctuations grow through gravity in an expanding universe.
supportedLarge-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.

Large-scale structure forms when small primordial density fluctuations grow through gravity in an expanding universe.
supportedDark matter begins clustering early because it does not couple strongly to radiation.
supportedSimulated halo abundances, galaxy clustering, filaments, voids, lensing statistics, and baryon distributions can be compared directly with surveys.
