Cluster Gravitational Redshifts as a Modified Gravity Probe

Auto-generated stub. Edit this file to add more details.

Using the gravitational redshift of galaxies within galaxy clusters to constrain deviations from General Relativity (GR) via a parameter $\alpha_{\mathrm{MG}}$.

Why It Matters

The entire paper focuses on establishing and quantifying the precision of this specific cosmological probe.

Evidence

investigate the impact of observational and theoretical uncertainties in cluster gravitational redshifts as a probe of modified gravity
