Abstract

In this paper, we explore various cosmological parameters and cosmological planes ($\omega_D-{\omega_D}^{\prime}$, statefinder) for new Tsallis agegraphic dark energy in the framework of Chern-Simons modified gravity. We consider this scenario in a flat FRW universe for both non-interacting and interacting cases, between dark energy and dark matter. It is observed that the equation of state parameter gives quintessence-like nature of the universe in all of the cases. Also, the squared of the sound speed shows unstable behaviour for this scenario. The $\omega_D-{\omega_D}^{\prime}$ plane represents the freezing region in most of the cases.
