The Recombination in a FRW Universe with a Variable Cosmological Term
Published online by Cambridge University Press: 25 May 2016
Abstract
The effects of a time-dependent A term in the recombination epoch are analysed taking into account the main physical processes occurring in the primordial plasma. For a vacuum decaying into photons, we show that the recombination begins when the Universe was smaller and denser, leading to a greater recombination rate. These results may have several implications to the large scale structure. In particular, the earlier recombination means that more time is available to the evolution of density perturbations.
