Dark Energy-Dark Matter Interaction from the Abell Cluster A586

TL;DR

This paper presents evidence of dark energy-dark matter interaction in the Abell Cluster A586, suggesting possible violations of the Equivalence Principle based on deviations from virial equilibrium.

Contribution

It provides observational evidence of dark sector interaction using cluster dynamics, a novel approach linking astrophysical data to fundamental physics.

Findings

Evidence of dark matter-dark energy interaction from cluster analysis

Potential violation of the Equivalence Principle

Supports models with interacting dark sectors

Abstract

We find that deviation from the virial equilibrium of the Abell Cluster A586 yields evidence of the interaction between dark matter and dark energy. We argue that this interaction might imply a violation of the Equivalence Principle. Our analysis show that evidence is found in the context of two different models of dark energy-dark matter interaction.
