Chapter 16
covers the dark ages, mostly through
theory and simulation.
Chapter 17 is galaxies and AGN, through cosmic epoch (k-corrections, mass, counts, evolution, etc.).
Chapter 18 focuses on star formation and element formation as a function of redshift.
Chapter 19 discusses the IGM.
The Gunn-Peterson
talk should hit on this. In general,
talks will cover the above
topics at some level.
