It has been suggested that Einstein's theory of general relativity can be modified to accommodate mismatches between the gravitational field and luminous matter on a wide range of scales. Covariant theories of modified gravity generically predict the existence of extra degrees of freedom which may be interpreted as dark matter. We study a subclass of these theories where the overall energy density in these extra degrees of freedom is subdominant relative to the baryon density. We find that… Expand

Modifications of gravity
General Relativity (GR) is a phenomenologically successful theory that rests on firm foundations, but has not been tested on cosmological scales. The deep mystery of dark energy (and possibly evenExpand

A general scheme for constructing consistent and covariant modifications to the Einstein equations is discussed, such that there is a clear connection between the modification and the underlying field content that produces it. Expand
Einstein’s Theory of Gravity and the Problem of Missing Mass
It emerges that theories of modified gravity remain viable but have become more complex, involving gravitating invisible elements, and the presence of dark fields reduces calculability and comes at the expense of the original MOND premise, that the matter the authors see is the sole source of gravity.

Testing the tensor-vector-scalar theory with the latest cosmological observations
The tensor-vector-scalar (TeVeS) model is considered a viable theory of gravity. It produces the Milgrom's modified Newtonian dynamics in the nonrelativistic weak field limit and is free from ghosts.Expand
TOPICAL REVIEW: The tensor-vector-scalar theory and its cosmology
Over the last few decades, astronomers and cosmologists have accumulated vast amounts of data clearly demonstrating that our current theories of fundamental particles and of gravity are inadequate toExpand
Modified Gravity and Cosmology
Abstract In this review we present a thoroughly comprehensive survey of recent work on modified theories of gravity and their cosmological consequences. Amongst other things, we cover GeneralExpand
Dark Matter Equation of State through Cosmic History.
These results constrain for the first time the level of "coldness" required of the DM across various cosmological epochs and show that the DM abundance is strictly positive at all times. Expand
Testing general relativity in cosmology
The review aims at providing an overall picture of the subject and an entry point to students and researchers interested in joining the field and a quick reference to recent results and constraints on testing gravity at cosmological scales. Expand
Power-law solutions for TeVeS
The dynamics of TeVeS in a homogeneous and isotropic universe is shown to be equivalent to the dynamics of an interacting two-component system, consisting of a scalar field and a 'fluid', related toExpand
Geometry of modified Newtonian dynamics
Modified Newtonian Dynamics is an empirical modification to Poisson's equation which has had success in accounting for the `gravitational field' $\Phi$ in a variety of astrophysical systems. TheExpand
