Admission requirements
Familiarity with basic concepts of cosmology is assumed. The student is assumed to have basic knowledge of the thermal history of the universe, recombination, the cosmic microwave background, cosmic distances, horizons, and to be able to work with the Friedmann equation. In terms of the Leiden curriculum, the Astronomy master's course Origin and Evolution of the Universe provides the ideal preparation.
Description
How galaxies and the largescale structures in which they are embedded form is a fundamental question in extragalactic astronomy. It is an area that has seen tremendous progress, but is still constantly challenged by everimproving observational data. This course introduces you to this fascinating subject and the underlying physics.
Physical concepts are derived from basic principles where possible. The emphasis is on intuitive rather than mathematically rigorous derivations.
Topics that will be covered include:
 Linear growth of density perturbations
 Free streaming
 Transfer functions and the matter power spectrum
 Nonlinear spherical collapse
 Jeans smoothing
 Radiation drag
 Statistical cosmological principle
 Clustering and biasing
 Halo mass functions and PressSchechter theory
 Scaling laws and virial relations
 Cosmic web
 Redshiftspace distortions
 Radiative cooling and its importance
 Angular momentum and its influence
 Reionization
 The GunnPeterson effect
 The thermal history of the intergalactic medium
 Feedback processes
 Halo models, semiempirical models, and simulations
Course objectives
Upon completion of this course you will understand how (we think that) largescale structures and galaxies form and evolve and you will be able to carry out calculations of the formation of structures in the universe.
Upon completion of the course you will be able to:
 Compute the growth of density fluctuations
 Compute the shape of the matter power spectrum
 Explain the morphology of the cosmic web
 Explain redshiftspace distortions
 Explain galaxy biasing and clustering
 Compute halo mass functions using PressSchechter theory
 Compute galaxy and halo scaling relations
 Understand radiative cooling processes
 Estimate the effect of radiative cooling on galaxy formation
 Estimate the effect of angular momentum on galaxy formation
 Model the process of reionization
 Compute the thermal history of the intergalactic medium
 Compute GunnPeterson absorption
 Understand the basics of feedback processes in galaxy formation
 Understand the basics of halo models, semiempirical models and simulations of galaxy formation
Soft skills
At the end of this course, you will have been trained in the following behaviororiented skills:
 Analytical skills (analytical thinking, abstraction, evidence)
 Structured thinking (structure, modulated thinking, computational thinking)
 Critical thinking (asking questions, check assumptions)
 Responsibility (ownership, selfdiscipline)
