Cosmic Structure Formation: From Fluctuations to Dark Matter Halos

Cosmological Background and Expansion → Excursion Set Theory

This learning path guides advanced undergraduate astronomy and physics students through the physical processes that shaped the cosmic web. Starting from the initial density fluctuations imprinted in the early universe, it covers the growth of perturbations via gravitational instability, the role of dark matter, and the statistical tools used to describe the resulting halo population.
