Extended Gravity Constraints at Different Scales

TL;DR

This paper reviews various methods to constrain extended gravity models across different scales, from galaxy clusters to particle physics, highlighting how precise data can test deviations from general relativity.

Contribution

It provides a comprehensive overview of observational and experimental constraints on extended gravity theories across multiple physical regimes.

Findings

Constraints from galaxy clusters and black hole shadows limit extended gravity models.

Gravitational wave and pulsar data provide bounds on deviations from GR.

High-energy physics experiments at LHC contribute to understanding gravity modifications.

Abstract

We review a set of the possible ways to constrain extended gravity models at Galaxy clusters scales (the regime of dark energy explanations and comparison with $\Lambda CDM$), for black hole shadows, gravitational wave astronomy, binary pulsars, Solar system and Large Hadron Collider (consequences for high energy physics at TeV scale). The key idea is that modern experimental and observational precise data gives a chance to go beyond the general relativity.
