Abstract

A particular class of flat Emergent Universe scenario is studied in light of recent observational data. Observationally permissible ranges of values are obtained for the model parameters. The class of model studied here can accommodate different composition of matter-energy as cosmic fluid. It is found that recent observations favour some compositions over others while some compositions can be ruled out with some level of confidence.
