Theory > s.a. chaotic
systems; cosmic strings; dark
matter; fluid; phenomenology
of inflation.
* Criteria: A theory has to explain the blackbody nature and isotropy
of microwave background.
* Primary mechanisms:
Protogalaxies can form from growth of primordial fluctuations, or aggregation
of material around cosmic string hoops or dark
matter; A protogalaxy forms a galaxy if the energy dissipation time
(by radiation) is smaller than the gravitational collapse time, otherwise it
is too hot
to collapse.
* Secondary mechanisms:
Triggered by shock waves from supernovas; Tidal interactions and mergers play
an important role in determining the kind
of
galaxy.
* Biasing: Characterized by the degenerate parameter combination 
= 
0.6/b, or just the linear bias parameter b, the ratio of the
fluctuation amplitudes of the galaxy and mass distributions.

* Interactions, mergers: In
the 1990's, evidence accumulates that interactions are common and very imporant
for galaxy evolution.
