In this work, we investigate the possibility that the galaxy rotation curves can be explained in the framework of modified gravity models that introduce a Yukawa term in the gravitational potential. We include dark matter and assume that the fifth-force couples differently to dark matter and to baryons. We aim at constraining the modified gravity parameters β and λ, that is, the strength and the range of the Yukawa fifth force, respectively, using a set of 40 galaxy rotation curves data from… 

Imprints of Chameleon f(R) Gravity on Galaxy Rotation Curves

Current constraints on gravity are relatively weak on galactic and intergalactic scales. Screened modified gravity models can exhibit complex behaviour there without violating stringent tests of

On the radial acceleration of disc galaxies

The physical processes defining the dynamics of disc galaxies are still poorly understood. Hundreds of articles have appeared in the literature over the last decades without arriving at an

Dark Matters on the Scale of Galaxies

The cold dark matter model successfully explains both the emergence and evolution of cosmic structures on large scales and, when we include a cosmological constant, the properties of the homogeneous

Constraints on quasidilaton massive gravity

The last decade has seen great advancements in the field of modified gravity, motivated by the dark energy problem, or by the search for a fundamental quantum gravity theory. With a

Galaxy rotation curves in the light of the Spinor Theory of Gravity

We analyze the recently obtained static and spherically symmetric solutions of the Spinor Theory of Gravity (STG) which, in the weak field limit, presents an effective Newtonian potential that

Observational constraints in nonlocal gravity: the Deser-Woodard case

We study the cosmology of a specific class of nonlocal model of modified gravity, the so-called Deser-Woodard (DW) model, modifying the Einstein-Hilbert action by a term ∼ R f(−1R), where f is a free

Long range effects in gravity theories with Vainshtein screening

In this paper we study long range modifications of gravity in the consistent framework of bigravity, which introduces a second massive spin-2 field and allows to continuously interpolate between the

A fundamental test for MOND

The radial acceleration relation (RAR) shows a strong correlation between two accelerations associated with galaxy rotation curves. The relation between these accelerations is given by a non-linear

Gravitational decoupling in cosmology

Dark matter candidate induced by Horndeski theory: Dark matter halo and cosmological evolution

We study spherically symmetric solutions with a scalar field in the shift-symmetric subclass of the Horndeski theory. Constructing an effective energy-momentum tensor of the scalar field based on the



Systematic biases on galaxy haloes parameters from Yukawa‐like gravitational potentials

A viable alternative to the dark energy as a solution of the cosmic speed up problem is represented by Extended Theories of Gravity. Should this be indeed the case, there will be an impact not only

Galaxy rotation curves in f(R,ϕ) gravity

We investigate the possibility to explain theoretically the galaxy rotation curves by a gravitational potential in total absence of dark matter. To this aim an analytic fourth-order theory of

Low surface brightness galaxy rotation curves in the low energy limit of Rn gravity: no need for dark matter?

We investigate the possibility that the observed flatness of the rotation curves of spiral galaxies is not evidence for the existence of dark matter haloes, but rather a signal of the breakdown of

Observational Tests of Nonlocal Gravity: Galaxy Rotation Curves and Clusters of Galaxies

aspect of gravity in this theory can simulate dark matter; indeed, in the Newtonian regime of nonlocal gravity, we recover the phenomenological Tohline-Kuhn approach to modified gravity. A simple

Rotation curves of galaxies by fourth order gravity

We investigate the radial behavior of galactic rotation curves by a Fourth Order Gravity adding also the Dark Matter component. The Fourth Order Gravity is a Lagrangian containing the Ricci scalar,

The MOG weak field approximation and observational test of galaxy rotation curves

As an alternative to dark matter models, MOdified Gravity (MOG) theory can compensate for dark matter by a covariant modification of Einstein gravity. The theory introduces two additional scalar

Galaxy rotation curves from general relativity with renormalization group corrections

We consider the application of quantum corrections computed using renormalization group arguments in the astrophysical domain and show that, for the most natural interpretation of the renormalization

Galaxy Rotation Curves without Nonbaryonic Dark Matter

We apply the modified acceleration law obtained from Einstein gravity coupled to a massive skew-symmetric field Fμνλ to the problem of explaining galaxy rotation curves without exotic dark matter.

Analysis of rotation curves in the framework of Rn gravity

ABSTRACT We present an analysis of a devised sample of Rotation Curves (RCs), aimed atchecking the consequences of a modified f(R) gravity on galactic scales. Originallymotivated by the the dark

Stellar kinematics from the symmetron fifth force in the Milky Way disk

It has been shown that the presence of non-minimally coupled scalar fields giving rise to a fifth force can noticeably alter dynamics on galactic scales. Such a fifth force must be screened in the
