The thermal history of the universe and the spectrum of relic radiation.
Abstract
It is shown that the final spectrum of relic radiation is influenced by each of the five stages in which the thermal history of the universe may be broken as a function of the redshift range. The influence of the energy release which heats the radiation at different stages of the expansion of the universe on the relic radiation spectrum is diagrammed for various values of Omega.
