Formation of Cosmic Structures
- starting point: tiny density fluctuations
- gravitational (Jeans) instability
- cold dark matter (CDM)
- hierarchical structure formation
- evidence for interactions: merging galaxies
- NGC 2623
- Arp 273
- galaxies "on a string"
- same a zooful
- and black holes
- Sagittarius dwarf galaxy cannibalism by the Milky Way!
- Magellanic stream cartoon, reality
- final result: observed structures today
Structure Formation: Baryons
- before recombination: acoustic oscillations
- at recombination: signature in the CMB here and here
- after recombination
Cosmic Star Formation
- star formation today: molecular clouds, clustered starbirth
- the first star: still, movie; more recent result--fragmentation!
- cosmic star formation history
