Observational constraints on the model parameters of a class of emergent universe

Show Summary Details

Preview

A class of emergent universe models is studied in the light of recent observational data. Significant constraints on model parameters are obtained from these observations. The density parameter for a class of models is also evaluated. Some of the models are in accordance with recent observations. Others are not of interest, yielding unrealistic present-day values of the density parameter.
