# Cosmological Tests of Gravity

@article{Ferreira2019CosmologicalTO, title={Cosmological Tests of Gravity}, author={Pedro G. Ferreira}, journal={arXiv: Cosmology and Nongalactic Astrophysics}, year={2019} }

Cosmological observations are beginning to reach a level of precision that allow us to test some of the most fundamental assumptions in our working model of the Universe. One such an assumption is that gravity is governed by the General Theory of Relativity. In this review we discuss how one might go about extending General Relativity and how such extensions can be described in a unified way on large scales. This allows us to describe the impact of modified gravity on the growth and morphology… CONTINUE READING
