| Chapter 15 covers the temperature fluctuations in the cosmic microwave background radiation. | ||
| Suggest reviewing the WMAP papers/webpages, Wayne Hu’s website, would be valuable. Links in Feb. lectures. | ||
| 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. | ||
| Lots of juicy stuff here that Longair placed outside of the scope of the course. Primary one in my mind is inflation, although magnetic fields, etc., are also important and interesting. | |
