Testing noncommutativity-like model as a galactic density profile

TL;DR

This paper tests a noncommutative-inspired galaxy density model against observational data to evaluate its effectiveness in explaining galactic rotation curves without dark matter.

Contribution

It introduces a noncommutative-like density profile model and compares its fit to galaxy data with the traditional Einasto profile using statistical criteria.

Findings

Some galaxies favor the NC-like model over Einasto.

The NC-like model can fit certain galactic rotation curves.

Results vary across the galaxy sample.

Abstract

Noncommutative-like model (NC-like) is an interesting alternative inspired by string theory to understand and describe the velocity rotation curves of galaxies without the inclusion of dark matter particles. In a natural way, a Gaussian density profile emerges and is characterized by a parameter {\theta}, called the NC-like parameter. Hence we aim to confront the NC-like model with a galaxy sample of the SPARC catalogue to constrain the model parameters and compare statistically with the Einasto density profile using the Akaike and Bayesian information criteria. According to our results, some galaxies prefer the NC-like over the Einasto model while others do not support NC-like.
