Non-spherical dark matter structures detection

TL;DR

This paper derives a rotation curve inequality for spherically symmetric mass distributions, tests it against galaxy data, and identifies candidates for non-spherical dark matter structures that require more precise measurements.

Contribution

It introduces a new inequality for detecting non-spherical dark matter structures and applies it to galaxy rotation data to identify potential candidates.

Findings

Identified galaxies that may host non-spherical dark matter structures

Derived a rotation curve inequality for spherical mass distributions

Proposed more precise measurements to confirm non-spherical structures

Abstract

A rotation curve inequality that holds for spherically symmetric mass distributions is derived, and tested against the SPARC galaxy rotation curves dataset. We identify several Galaxies, eg NGC7793 and UGC05253, which are candidates for hosting non-spherical dark matter structures that could be detected by more precise measurements.
