The Thermal History of the Universe work out the thermal history of the matter and radiation content of the standard Big Bang picture. In this and the succeeding Chap. 10, we will develop many concepts which are essential for understanding the problems of galaxy formation. Let us first consider the dynamics of radiation-dominated universes.

Hans-Hermann Fernholz,Heinrich E. Fiedlerutrinos provide an example of the decoupling processes which may be important for other unknown types of weakly interacting particle. We will find a qualitatively similar example when we study possible forms of the dark matter.

B. Kadoch,W. J. T. Bos,K. SchneiderUniverse must be in some non-baryonic form. We need to convince ourselves of the reasoning behind this dramatic conclusion — the nature of the non-baryonic dark matter is of fundamental importance for physics and cosmology.

Galaxiesared with, say, the physics of the stars..This is an enormous subject and we will only touch on some of the more important aspects of galaxies, as well as elucidating some of the essential physics. In the next chapter, we will perform a similar exercise for clusters of galaxies.

Clusters of Galaxiesonment. Interactions of galaxies with each other and with the intergalactic medium in the cluster can be studied, as well as the distribution and nature of the dark matter, which dominates their dynamics. These are key topics for the physics of galaxy formation.

The Theoretical Frameworkretation of the space and time coordinates to be used in these calculations. For example, de Sitter’s solution for an empty universe could be written in apparently stationary form, or as an exponentially expanding solution. By 1935, the problem was solved independently by Robertson and Walker. They
