Astrophysical constraints and insights on extended relativistic gravity

Abstract

We give precise details to support that observations of gravitational lensing at scales of individual, groups and clusters of galaxies can be understood in terms of non-Newtonian gravitational interactions with a relativistic structure compatible with the Einstein Equivalence Principle. This result is derived on very general grounds without knowing the underlying structure of the gravitational field equations. As such, any developed gravitational theory built to deal with these astrophysical scales needs to reproduce the obtained results of this article.

A Critique of Covariant Emergent Gravity

“…0 of this result reproduces the one obtained in [35]. Since the MOND solution belongs to the large family defined by the condition R = 0, it exists for all λ > 1.…”

A critique of covariant emergent gravity

“…For λ > 1, the last term, proportional to k 2 , would not be present, and the special case k 1 = k 2 = 0 of this result reproduces the one obtained in [40]. Since the MOND solution belongs to the large family defined by the condition R = 0, it exists for all λ > 1.…”
