FLRW accelerating universe with interactive dark energy

Abstract

We have developed an accelerating cosmological model for the present universe which is phantom for the period $(0\le z\le 1.99)$ and quintessence phase for $(1.99\le z\le 2.0315)$. The universe is assumed to be filled with barotropic and dark energy(DE) perfect fluid in which DE interact with matter. For a deceleration parameter(DP) having decelerating-accelerating transition phase of universe, we assume hybrid expansion law for scale factor. The transition red shift for the model is obtained as $z_t=0.956$. The model satisfies current observational constraints.
