Dark Matter: Properties and Behavior in the Early Universe - Lecture 1

Dark Matter: Properties and Behavior in the Early Universe - Lecture 1

Explore the mysteries of dark matter in this comprehensive lecture from the Physics of the Early Universe program. Delve into empirical knowledge about dark matter, its thermal history, and constraints from Big Bang nucleosynthesis. Examine the effects of dark matter on cosmology, including small-scale clustering and the Lyman-alpha forest. Investigate the behavior of perturbations in the pre-recombination fluid and the interactions of dark matter in the early universe. Learn about constraints on dark matter constituent mass, considering both bosonic and fermionic possibilities. Discover approaches to understanding the vast range of dark matter possibilities, including thermal production mechanisms. Gain insights into cutting-edge research on dark matter's role in the formation and evolution of the universe.
