Effect of the field self-interaction of General Relativity on the Cosmic Microwave Background Anisotropies

TL;DR

This paper investigates how the non-linear self-interactions in General Relativity influence the Cosmic Microwave Background anisotropies, potentially reducing the reliance on dark matter and dark energy in cosmological models.

Contribution

It introduces an analysis of field self-interactions in General Relativity and their impact on CMB anisotropies, offering an alternative perspective to dark matter and dark energy.

Findings

Self-interactions can reduce the need for dark matter.

Self-interactions can lessen the requirement for dark energy.

Alterations in the CMB power spectrum due to self-interactions.

Abstract

Field self-interactions are at the origin of the non-linearities inherent to General Relativity. We study their effects on the Cosmic Microwave Background anisotropies. We find that they can reduce or alleviate the need for dark matter and dark energy in the description of the Cosmic Microwave Background power spectrum.
