Generalized ghost pilgrim dark energy in f(G, T) gravity

In this paper, we explore the reconstruction paradigm for generalized ghost pilgrim dark energy model with f(G, T) gravity (G is the Gauss-Bonnet invariant and T is the trace of the energy-momentum tensor) depending upon the speculation of black hole-free universe. To accomplish this, we adopt correspondence scheme for dust fluid configuration with flat Friedmann-Robertson-Walker (FRW) universe. The cosmic behavior of reconstructed models is examined through cosmological diagnostic parameters and phase planes. It is found that the deceleration parameter indicates accelerated phase while equation-of-state parameter represents phantom regime for some specific range of free parameters. The squared speed of sound parameter gives stable models for analyzing evolutionary paradigm of the universe. The trajectories of omega(de)-omega'(de) plane gives thawing region, whereas r-s phase plane corresponds to Chaplygin gas model. We conclude that the resulting model represents self-consistent phantom-like universe for u < 0 (u cannot be fraction) as well as stable generalized ghost pilgrim dark energy f(G, T) model.
