Galaxy Formation -- a Condensation Process just after Recombination

A scenario of galaxy formation is put forward which is a process of sudden condensation just after recombination. It is essentially based on the fact that the cosmic matter gas after recombination is a general relativistic Boltzmann gas which runs within a few $10^6$ years into a state very close to collision--dominated equilibrium. The mass spectrum of axially symmetric condensation "drops" extends from the lower limit M about $10^5$ solar masses to the upper limit M about $10^{12}$ solar masses. The lower limit masses are spheres whereas the upper limit masses are extremely thin pancakes. These pancakes contract within a time of about $2.5 \cdot 10^9 y$ to fastly rotating spiral galaxies with ordinary proportions. In this final state they have a redshift z about 3. At an earlier time during their contraction they are higly active and are observed with a redshift z about 5.
