文摘

We study the cosmic acceleration in dynamical Chern-Simons modified gravity in the frame-work of non-flat FRW universe. The pilgrim dark energy (with future event and apparent horizons) interacted with cold dark matter is being considered in this work. We investigate the cosmological parameters (equation of state, deceleration) and planes (state-finders, \(\omega_{\vartheta }\)–\(\omega_{\vartheta }^{\prime }\)) in the present scenario. It is interesting to mention here that the obtained results of various cosmological parameters are consistent with various observational schemes. The validity of generalized second law of thermodynamics for present dark energy models is also being analyzed.KeywordsDynamical Chern-Simons modified gravityDark energy modelsCosmological parameters and planeGeneralized second law of thermodynamic
