Perturbation in an interacting dark universe

Understand

In this paper we have considered an interacting model of dark energy and have looked into the evolution of the dark sectors.

• By solving the perturbation equations numerically, we have studied the imprints on the growth of matter as well as dark energy fluctuations.
• It has been found that for higher rate of interaction strength for the coupling term, visible imprints on the dark energy density fluctuations are observed at the early epochs of evolution.
