Galaxy Groups & Clusters: Foundations
Galaxies are strongly clustered rather than randomly distributed. Clusters are laboratories for dark matter, plasma physics, galaxy environmental evolution, cosmology, and large-scale structure growth.

Most ordinary matter in a rich galaxy cluster is not locked in stars; it resides in a diffuse, extremely hot ionized plasma called the intracluster medium. The intracluster medium measures cluster mass and thermodynamic history, reveals feedback from central black holes, and provides cosmological probes relatively independent of optical light.

Dark-matter halos dominate the mass budgets of many galaxies and galaxy clusters. Lensing constrains halo profiles, cluster masses, cosmological structure growth, substructure, and the distribution of dark matter during galaxy collisions.

On scales much larger than individual clusters, galaxies form a cosmic web of filaments, sheets, nodes, and vast underdense voids. Large-scale structure tests cosmological models, dark matter, dark energy, neutrino masses, and the statistical properties of primordial fluctuations.

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.
