Resolution of dark matter problem in f(T) gravity

TL;DR

This paper proposes a torsion-based f(T) gravity model that explains galaxy rotation curves and dark matter density profiles, aligning well with empirical data and suggesting dark matter effects originate from space torsion.

Contribution

It introduces a novel f(T) gravity model that accounts for dark matter phenomena without invoking unseen particles, providing an alternative explanation based on torsion.

Findings

Successfully reproduces flat galaxy rotation curves

Derives dark matter density profiles consistent with observations

Shows dark matter effects can be explained by space torsion

Abstract

In this paper, we attempt to resolve the dark matter problem in f(T) gravity. Specifically, from our model we successfully obtain the flat rotation curves of galaxies containing dark matter. Further, we obtain the density profile of dark matter in galaxies. Comparison of our analytical results shows that our torsion-based toy model for dark matter is in good agreement with empirical data-based models. It shows that we can address the dark matter as an effect of torsion of the space.
