Luminosity distance in GX cosmological models

TL;DR

This paper derives a luminosity distance formula within GX cosmological models, showing it depends only on matter and curvature parameters, and compares it with observational data.

Contribution

It introduces a luminosity distance equation specific to GX cosmological models and analyzes its dependence on fundamental constants and parameters.

Findings

Luminosity distance in GX models is independent of the speed of light and gravitational constant.

The distance depends solely on matter parameter and curvature.

Model comparison with supernovae and radio galaxy data shows consistency.

Abstract

We derive luminosity distance equation in Gurzadyan-Xue cosmological models and compared it with available supernovae and radio galaxies data sets. We found that the luminosity distance does not depend explicitly the speed of light and the gravitation constant, and depends only on the matter parameter (GX-invariant) and curvature.
