New Tsallis agegraphic Dark Energy in Chern-Simons modified gravity

preprint2020arXivOpen access

Abstract

In this paper, we explore various cosmological parameters and cosmological planes (ωD−ωD′ω_D-{ω_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 ωD−ωD′ω_D-{ω_D}^{\prime} plane represents the freezing region in most of the cases.
