Aspects of Some New Versions of Pilgrim Dark Energy in DGP Braneworld

Abstract

The illustration of cosmic acceleration under two interacting dark energy models (pilgrim dark energy with Granda and Oliveros cutoff and its generalized ghost version) in DGP braneworld framework is presented. In the current scenario, the equation of state parameter, deceleration parameter, $\omega_{D}-\omega'_{D}$ plane and statefinder diagnosis are investigated. The equation state parameter behave-like phantom era of the universe. The deceleration parameter depicts the accelerated expansion of the universe in both models. The cosmological planes like $\omega_{D}-\omega'_{D}$ and statefinder corresponds to $\Lambda$CDM limit. To end, we remark that our results support to phenomenon of pilgrim dark energy and cosmic acceleration. Also, the results are consistent with observational data.
