• Jeans instability
• spherical collapse model
• hierarchical structure formation
• the growth of structure: theory, observation
• simulation from rotating perpsective
• same simulation using physical=non-expanding versus expanding coordinates
• the the cosmic web writ large and zooming in
• a galaxy cluster merger
• evidence for interactions: merging galaxies
  NGC 2623 , Arp 273, galaxies "on a string"
