The galactic rotation curve of a magnetized plasma cloud

TL;DR

This paper demonstrates that a weak, decreasing magnetic field in a galactic plasma cloud can produce a flat rotation curve, aligning with observations, through statistical analysis.

Contribution

It introduces a novel statistical approach showing how magnetic fields can explain flat galactic rotation curves without dark matter.

Findings

Magnetic fields influence plasma cloud rotation.

Probability density aligns with flat rotation curves.

Supports magnetic explanation for galaxy dynamics.

Abstract

The rotation curve of a magnetized plasma cloud orbiting in the gravitational potential of a galaxy is calculated by statistical arguments. The working assumption is that a mild magnetic field, decreasing with distance from the galactic center, permeates space. It is shown that the resulting probability density is compatible with a flat rotation curve.
