Testing the interaction of dark energy to dark matter through the analysis of virial relaxation of clusters Abell Clusters A586 and A1689 using realistic density profiles

TL;DR

This study investigates the potential interaction between dark energy and dark matter by analyzing the virial equilibrium of two galaxy clusters using realistic density profiles, finding no evidence of interaction.

Contribution

It introduces a method to test dark energy-dark matter interaction through virial analysis with realistic density profiles of galaxy clusters.

Findings

Virial ratios are consistent with no interaction.

Realistic density profiles improve the accuracy of virial analysis.

No significant deviation from equilibrium suggests no dark energy-dark matter interaction.

Abstract

Interaction between dark energy and dark matter is probed through deviation from the virial equilibrium for two relaxed clusters: A586 and A1689. The evaluation of the virial equilibrium is performed using realistic density profiles. The virial ratios found for the more realistic density profiles are consistent with the absence of interaction.
