Dark Energy-Dark Matter Interaction from the Abell Cluster A586 and violation of the Equivalence Principle

TL;DR

This paper presents evidence of interaction between dark energy and dark matter in the Abell Cluster A586, which may indicate a violation of the Equivalence Principle across two models.

Contribution

It provides observational evidence linking dark sector interaction to fundamental physics principles, specifically the Equivalence Principle.

Findings

Evidence of dark matter-dark energy interaction in A586

Potential violation of the Equivalence Principle

Analysis across two different interaction models

Abstract

We find that the Abell Cluster A586 exhibits evidence of the interaction between dark matter and dark energy and argue that this interaction suggests evidence of violation of the Equivalence Principle. This violation is found in the context of two different models of dark energy-dark matter interaction.
