Galactic sparsity and $\Lambda$-gravity

TL;DR

This paper investigates the sparsity parameter of galaxy clusters within the framework of $ abla$-gravity, demonstrating its potential as a new test to distinguish between General Relativity and alternative gravity theories.

Contribution

It introduces the use of the sparsity parameter as a novel observational test for $ abla$-gravity, aligning theoretical estimates with observed data within error margins.

Findings

Theoretical sparsity values match observed data within error limits.

Sparsity parameter can serve as a new test for gravity theories.

Future measurements can utilize sparsity to detect deviations from General Relativity.

Abstract

The sparsity parameter for clusters of galaxies is obtained in the context of $\Lambda$-gravity. It is shown that, the theoretical estimated values are within the reported error limits of the measured data. Thus, in the future the sparsity parameter can serve as an informative new test to detect the discrepancy between General Relativity and $\Lambda$-gravity.
