Outline

1	ASTR 5460, Fri. Apr. 25, 2003 Reminders/Assignments Finish Chapter 10 from Longair: Nucleosynthesis in the Early Universe
2	Reminders/Assignments FIRST/NVSS and 2MASS reports Wed. Discussion/comments/questions regarding the Physics Today Articles? Research Homework Update Dan finished phase 1, will start phase 2 Chris, Sey, and Cassandra primary now Presentation topics Read Shields “A Brief History of AGN” astro-ph/9903401 astro-ph papers at end of class if time
3	Presentation Topics Last week of class, 2 Wed., 4 Fri. Plan for 20 minutes, plus questions. Web-based powerpoint encouraged. Topics: Gunn-Peterson Test and Reionization Supernovae and the Accelerating Universe Weighing Supermassive Black Holes The Hubble Deep Fields Sub-millimeter (SCUBA) Galaxies X-ray Background
4	Sloan Post-starburst Quasars Background in papers/proposals Tasks Identify from the SDSS EDR spectra (two levels) – lots of effort now vs. later Morphology from SDSS images (two levels) Bruzual & Charlot ISB modeling Quasar measurements, derived properties Compiling statistics, correlation analyses (lots of effort later vs. now) Oversight, science, figures/tables, etc. Will require individual meetings

19	Jean’s Mass, Horizon mass, with scale factor
20	What goes wrong with baryon-only cosmologies?
21	Dark Matter and Galaxy Formation
22	Hot Dark Matter
23	Cold Dark Matter
24	Spectrum of Initial Fluctuations
25	The Hubble Deep Field
26	Evidence for “Hierarchical” Galaxy Formation from the HDF
27	What this might look like Movie simulation of galaxy formation via assembly of small pieces (courtesy of Space Telescope Science Institute): http://imgsrc.stsci.edu/op/pubinfo/mpeg/galaxies.mpg
28	Structure Simulations
29	Structure Simulations
30	Concluding Remarks 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.
31	Concluding Remarks 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.
32	Chapter 20: Final Things 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.
