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 ≤ z ≤ 1.99) and quintessence phase for (1.99 ≤ z ≤ 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 zt = 0.956. The model satisfies current observational constraints.
