From observations it is deduced that the disk and halo were formed about the same time and that most of the previously gaseous Galaxy became stars then. Dimensional analysis indicates that the flattening of a galaxy is related to its energy,E, angular momentum,H, and mass,M, by the dimensionless number - 2EH2/G5M5.

Galaxy Formation and Evolution
Space Science Reviews, 2016In this chapter, we discuss the current status of observational and computational studies on galaxy formation and evolution. In particular, a joint analysis of star-formation rates (SFRs), stellar masses, and metallicities of galaxies throughout cosmic time can shed light on the processes by which galaxies build up their stellar mass and enrich the ...

We investigate the process of galaxy formation as can be observed in the only currently forming galaxies — the so-called Tidal Dwarf Galaxies, hereafter TDGs — through observations of the molecular gas detected via its CO (Carbon Monoxide) emission. These objects are formed of material torn off of the outer parts of a spiral disk due to tidal forces in

The formation of galaxies from density perturbations is discussed, and it is shown that the Galaxy could have grown from a typical isolated peak in the now-fashionable “cold dark matter” model; most of its properties are correctly predicted by such a model.
