摘要
In this paper, we analyze the reconstruction paradigm for pilgrim dark energy model with f(G, T) gravity using Hubble horizon as IR-cutoff. To accomplish this, we use correspondence scheme for dust fluid configuration with flat FRW universe. The cosmological behavior of reconstructed model is examined through cosmic diagnostic parameters and phase planes. It is found that the deceleration parameter indicates accelerated phase while equation of state parameter represents phantom regime. The squared speed of sound parameter gives stable model for analyzing current cosmic evolutionary paradigm. The trajectories of omega(de) - omega'(de) plane gives the thawing region, whereas r - s phase plane corresponds to Chaplygin gas model. We conclude that the resulting model represents aggressive phantom-like universe for u < 0 (with odd choices only), as well as self-consistent PDE f(G, T) model.
