Observational evidences of the Yukawa Potential Interacting Dark Matter

TL;DR

This paper demonstrates that dark matter interacting via a Yukawa potential can explain core-like structures in galaxies and clusters, deriving scaling relations that match observations and constraining particle properties.

Contribution

It introduces a Yukawa potential interaction model for dark matter that explains core structures and derives scaling relations consistent with observational data.

Findings

Yukawa potential interactions produce core-like dark matter profiles.

Derived scaling relations match galactic and cluster observations.

Constraints on dark matter and force carrier masses are obtained.

Abstract

Recent observations in galaxies and clusters indicate dark matter density profiles exhibit core-like structures which contradict to the numerical simulation results of collisionless cold dark matter. On the other hand, it has been shown that cold dark matter particles interacting through a Yukawa potential could naturally explain the cores in dwarf galaxies. In this article, I use the Yukawa Potential interacting dark matter model to derive two simple scaling relations on the galactic and cluster scales respectively, which give excellent agreements with observations. Also, in our model, the masses of the force carrier and dark matter particle can be constrained by the observational data.
