Darkon fluid - a model for the dark sector of the Universe?

TL;DR

This paper proposes a darkon fluid model with anisotropic scaling that dynamically generates gravitational mass density, potentially explaining the Universe's dark sector and its accelerating expansion.

Contribution

It introduces a novel darkon fluid with specific scaling properties that can model dark matter and dark energy phenomena in cosmology.

Findings

The model exhibits a deceleration phase in early Universe cosmology.

It predicts an acceleration phase in late Universe evolution.

Potential for steady flow solutions to produce confining halos.

Abstract

We introduce darkons as fluid particles of a Galilean massless self-gravitating fluid. This fluid exhibits anisotropic scaling with $z=5/3$. The minimal gravitational coupling dynamically generates a gravitational mass density of either sign. Hence such fluid may serve as a model for the dark sector of the Universe. Its cosmological solutions give a deceleration phase for the early Universe and an acceleration phase for the late Universe. Will the steady flow solutions lead to a confining potential and so a possible model for halos?
