Abstract

The paper is devoted to the study of the cosmic acceleration through ghost dark energy models (its simple and generalized form) in the dynamical Chern-Simons modified gravity. In order to check the reliability of this scenario, we explore different cosmological parameters, such as deceleration, equation of state parameters and squared speed of sound. The cosmological planes - ′_D and r-s are also investigated in this framework. The obtained results are consistent with observational data of various schemes (WMAP+eCAMB+BAO+H₀).
