Study of growth matter index and cosmic implications in dynamical Chern–Simons modified gravity

Study of growth matter index and cosmic implications in dynamical Chern–Simons modified gravity

Abstract In the framework of dynamical Chern–Simons theory of gravity, we study the recent cosmic expansion with acceleration of the universe. We take interacting scenario of dark energy and dark matter with three cutoffs like Granda–Oliveros, higher order derivative of Hubble parameter and generali...
