A Dark Energy Quintessence Model of the Universe
arXiv:1905.10801 · doi:10.1142/S0217732320500029
Abstract
In this paper, we have presented a model of the FLRW universe filled with matter and dark energy fluids, by assuming an ansatz that deceleration parameter is a linear function of the Hubble constant. This results in a time-dependent DP having decelerating-accelerating transition phase of the universe. This is a quintessence model . The quintessence phase remains for the period . The model is shown to satisfy current observational constraints. Various cosmological parameters relating to the history of the universe have been investigated.
