Formation of Cosmic Structures

Cosmic Structure Observed

• today: galaxy surveys, e.g., 2dF, SDSS
• at recombination: CMB sky of Planck

Structure Formation Theory

• Jeans instability
• cold dark matter (CDM)
• hierarchical structure formation
• the growth of structure: theory, observation
• same simulation using physical=non-expanding versus expanding coordinates
• the cosmic web
• a galaxy cluster merger
• the first star: still, movie
