Velocity distribution of elliptical galaxies in the framework of Non-local Gravity model

TL;DR

This paper demonstrates that Non-local Gravity can explain the velocity distribution of elliptical galaxies and reproduce their fundamental plane without invoking dark matter, aligning theory with observations.

Contribution

It introduces a non-local gravity framework to model elliptical galaxy dynamics, successfully fitting observational data without dark matter.

Findings

Non-local Gravity reproduces elliptical galaxy velocity profiles.

The model fits the fundamental plane observational data.

Dark matter is not necessary in this framework.

Abstract

We investigate the velocity distribution of elliptical galaxies in the framework of Non-local Gravity. According to this approach, it is possible to recover the fundamental plane of elliptical galaxies without the dark matter hypothesis. Specifically, we compare theoretical predictions for circular velocity in Non-local Gravity context with the corresponding values coming from a large sample of observed elliptical galaxies. We adopt the surface brightness, effective radius and velocity dispersion as structural parameters for the fundamental plane. As final result, it is possible to show that non-local gravity effects can reproduce the stellar dynamics in elliptical galaxies and fit consistently observational data.
