Radial acceleration relation and dissipative dark matter

TL;DR

This paper demonstrates that dissipative dark matter models, such as mirror dark matter, can naturally reproduce the observed tight correlation between baryonic matter and gravitational acceleration in galaxies.

Contribution

It shows that dissipative dark matter models can explain the radial acceleration relation, linking dark matter profiles to baryonic matter.

Findings

Dissipative dark matter models reproduce the radial acceleration relation.

Dark matter density profiles align with observed galactic dynamics.

Supports dissipative dark matter as a viable explanation for galactic structure.

Abstract

Observations indicate that ordinary matter, the baryons, influence the structural properties of dark matter on galactic scales. One such indication is the radial acceleration relation, which is a tight correlation between the measured gravitational acceleration and that expected from the baryons. We show here that the dark matter density profile that has been motivated by dissipative dark matter models, including mirror dark matter, can reproduce this radial acceleration relation.
