Contribution
It investigates the emergent universe scenario with modified Chaplygin gas and identifies parameter conditions under which it is feasible.
Findings
Emergent scenario possible with specific parameter choices.
Requires unrealistic parameter values for emergence.
Contributes to understanding of alternative cosmological models.
Abstract
The present work is an attempt for emergent universe scenario with modified Chaplygin gas. The universe is chosen as spatially flat FRW space-time with modified Chaplygin gas as the only cosmic substratum. It is found that emergent scenario is possible for some specific (unrealistic) choice of the parameters in the equation of state for modified Chaplygin gas.
