“…Our results are consistent with them for non-interacting case with μ = 1.55 and ν = 1.91. Jawad and Rani [18] investigated the reconstructed models, their stability and EoS parameter in the modified Horava-Lifshitz f (R) gravity. Our results are in great agreement with their work.…”

“…According to this technique, one has to equate energy densities of corresponding DE model and modified theory to derive a reconstructed model. Jawad and Rani [18] discussed GGPDE model by applying this technique in Horava-Lifshitz f (R) gravity. Sharif and Nazir [19] worked on this technique by assuming GGPDE f (T ) model and investigated the behavior of different cosmological parameters.…”

In this paper, we analyze cosmological consequences of the reconstructed generalized ghost pilgrim dark energy F(T, T G ) models in terms of redshift parameter z. For this purpose, we consider power-law scale factor, scale factor for two unified phases and intermediate scale factor. We discuss graphical behavior of the reconstructed models and examine their stability analysis. Also, we explore the behavior of equation of state as well as deceleration parameters and ω − ω as well as r − s planes. It is found that all models are stable for pilgrim dark energy parameter 2. The equation of state parameter satisfies the necessary condition for pilgrim dark energy phenomenon for all scale factors. All other cosmological parameters show great consistency with the current behavior of the universe.

In this paper, we analyze cosmological consequences of the reconstructed generalized ghost pilgrim dark energy F(T, T G ) models in terms of redshift parameter z. For this purpose, we consider powerlaw scale factor, scale factor for two unified phases and intermediate scale factor. We discuss graphical behavior of the reconstructed models and examine their stability analysis. Also, we explore the behavior of equation of state as well as deceleration parameters and ω Λ − ω ′ Λ as well as r − s planes. It is found that all models are stable for pilgrim dark energy parameter 2. The equation of state parameter satisfies the necessary condition for pilgrim dark energy phenomenon for all scale factors. All other cosmological parameters show great consistency with the current behavior of the universe.

“…Jawad and Rani [26] considered Horava-Lifshitz f (R) to reconstructed the GGPDE model and the same authors reconstructed PDE model in the background of f (G) gravity, respectively. They conclude that the recontracted dynamical model points out towards different DE scenarios.…”

This paper is devoted to explore the cosmic evolution of non-flat Friedmann Robertson Walker universe through generalized ghost pilgrim dark energy model in the background of f (R) gravity. For this purpose, we consider two well known scale factors, i.e., power-law and unified scale factors in terms of red shift parameter. For these scale factors, we reconstruct the given dark energy model in f (R) gravity and determine its stability/instability through squared speed of sound parameter. In order to discuss the behavior of reconstructed and dark energy models, we evaluate well known cosmological parameter such as equation of state parameter along with ω-ω plane. In addition to this, we also investigate compatibility of new models with standard cosmological models through state-finder parameters. The density parameter is formulated for both ordinary matter as well as dark energy components and results are compared with Planck 2018 constraints. It is concluded that cosmological parameters reveal consistency with recent observations while the value of density parameter suggested by Planck 2018 is achieved by power-law scale factor in most of the cases as compared to unified scale factor.
