Emergent Universe from A Composition of Matter, Exotic Matter and Dark Energy

Abstract

A specific class of flat Emergent Universe (EU) is considered and its viability is tested in view of the recent observations. Model parameters are constrained from Stern data for Hubble Parameter and Redshift ($H(z)$ vs. $z$) and from a model independent measurement of BAO peak parameter. It is noted that a composition of Exotic matter, dust and dark energy, capable of producing an EU, can not be ruled out with present data. Evolution of other relevant cosmological parameters, viz. density parameter ($Ω$), effective equation of state (EOS) parameter ($ω_{eff}$) are also shown.
