Observational scalings testing modified gravity

TL;DR

This paper tests modified gravity theories involving the cosmological constant using observational data from galaxy clusters, gravitational waves, and galaxy relations, finding results consistent with standard cosmological predictions.

Contribution

It introduces a comprehensive observational approach to constrain the cosmological constant within modified gravity frameworks using multiple astrophysical phenomena.

Findings

Upper limits for the cosmological constant are consistent with standard cosmological values.

Scaling relations in galaxy clusters support the modified gravity approach.

Gravitational wave power measurements align with existing cosmological constant estimates.

Abstract

We consider different observational effects to test modified gravity approach involving the cosmological constant in the common description of the dark matter and the dark energy. We obtain upper limits for the cosmological constant by studying the scaling relations for 12 nearby galaxy clusters, the radiated power from gravitational waves and the Tully-Fisher relation for super spiral galaxies. Our estimations reveal that, for all these cases the upper limits for $\Lambda$ are consistent with its actual value predicted by the cosmological observations.
