The model of dark galactic halo based on equilibrium distribution function

TL;DR

This paper develops a kinetic theory-based model of dark galactic halos using Maxwell-Boltzmann distribution, explaining flat rotation curves and aligning with classical gas cloud models in Newtonian gravity.

Contribution

It introduces a kinetic theory approach to model dark matter halos, providing a new explanation for observed galactic rotation curves.

Findings

The model explains flat rotation curves of galaxies.

Results align with classical spherical gas cloud models.

Uses Maxwell-Boltzmann distribution for equilibrium analysis.

Abstract

The model of galactic halo as a system of the collisionless small neutral particles from the standpoint of kinetic theory is considered. For the equilibrium system with the use of Maxwell-Boltzmann distribution we obtained results which explain the observed flat rotation curve. These results practically coincide with the results of equilibrium spherical gas cloud model in Newtonian gravitation with linear state equation.
