Abstract
In this paper we have considered an interacting model of dark energy where the dark sectors are allowed to interact among themselves through an assumed relation. 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. In order to check the viability of the model, we have tested the interacting model with different observational datasets and have looked into the evolution of the density contrast, and the effects on the CMB temperature fluctuation as well as matter power spectrum.
