Observational constraints in metric-affine gravity

Observational constraints in metric-affine gravity

Abstract We derive the main classical gravitational tests for a recently found vacuum solution with spin and dilation charges in the framework of Metric-Affine gauge theory of gravity. Using the results of the perihelion precession of the star S2 by the GRAVITY collaboration and the gravitational re...
