Density perturbation in the models reconstructed from jerk parameter

TL;DR

This paper investigates the evolution of density perturbations in dark energy models reconstructed from the jerk parameter, finding non-interacting models are more favored than interacting ones.

Contribution

It introduces a method to analyze density perturbations in reconstructed dark energy models based on the jerk parameter, highlighting the preference for non-interacting models.

Findings

Non-interacting models are favored over interacting models.

Density contrast evolution is studied in reconstructed dark energy models.

The jerk parameter approach provides insights into late-time cosmic evolution.

Abstract

The present work deals with the late time evolution of the linear density contrast in the dark energy models reconstructed from the jerk parameter. It is found that the non-interacting models are favoured compared to the models where an interaction is allowed in the dark sector.
