17. GROWTH OF STRUCTURE

This Topic has not yet been prepared. Maybe next time (Spring 2007)

(1) Introduction

Outline basic sequence -- postpone some themes to Topic 18

(2) Descriptions of Density Fields

Overview -- different types
include brief history of usage
clarify scales and ranges and dimensions
use & importance of window functions
include how to normalize
include discussion of Gaussianity
Any practial aspects of calculating these from real data.

(3) Initial Power Spectra

Include some history -- isothermal/adiababtic 1970s; isocurvature/adiababitc now.
discuss meaning of "scale invariant"
include several kinds of IPS -- and their weaknesses.

(4) Evolution of Density Fluctuations

preliminary version

(5) Baryon Acoustics & Structures
