Modified gravity theories with a screening mechanism have acquired much interest recently in the quest for a viable alternative to General Relativity on cosmological scales, given their intrinsic property of being able to pass Solar System scale tests and, at the same time, to possibly drive universe acceleration on much larger scales. Here, we explore the possibility that the same screening mechanism, or its breaking at a certain astrophysical scale, might be responsible of those gravitational…

Hubble tension vs two flows
The Hubble tension is shown to be solvable, without any free parameter, conceptually and quantitatively, within the approach of modified weak-field General Relativity involving the cosmological
mg-mamposst: a code to test modifications of gravity with internal kinematics and lensing analyses of galaxy clusters
We present an upgraded version of \emph{MG-MAMPOSSt}, a code to constrain modified gravity models with the dynamics of galaxy cluster's members, based on the original \emph{MAMPOSSt} method, along
On the Lambda-evolution of galaxy clusters
The evolution of galaxy clusters can be affected by the repulsion described by the cosmological constant. This conclusion is reached within the modified weak-field General Relativity approach where
PPN rotation curves in static distributions with spherical symmetry
From a Parametrized Post-Newtonian (PPN) [46-51] perspective, we address the question of whether or not the new degrees of freedom, represented by the PPN potentials, can lead to significant
Probing screened modified gravity with nonlinear structure formation
We review the effects of modified gravity theories, in particular the symmetron and f(R) gravity, on the nonlinear regime of structure formation. In particular, we investigate the velocity dispersion
Testing the Cubic Galileon Gravity model by the Milky Way rotation curve and SPARC data
Recently, the Cubic Galileon Gravity (CGG) model has been suggested as an alternative gravity theory to General Relativity. The model consists of an extra field potential term which can serve as the
The cosmological constant vs adiabatic invariance
. The property of adiabatic invariance is studied for the generalized potential satisfying the condi-tion of identity of sphere’s and point mass’s gravity. That function contains a second term
Generalized McVittie geometry in Horndeski gravity with matter
We investigate McVittie and generalized McVittie solutions for Horndeski gravity with a spatially homogeneous gravitational scalar field, which is stealth at small scales near the central object but,
Classification of the Horndeski cosmologies via Noether symmetries
Adopting Noether point symmetries, this work classify and integrate dynamical systems coming from Horndeski cosmologies and derives several modified theories of gravity like f(R) gravity, Brans–Dicke gravity, string inspired gravity and so on.
Standard Models and What Lies Beyond
The backbone of particle physics and cosmology consists of two Standard Models, providing the mathematical description of these two fields.


Extended theories of gravity and their cosmological and astrophysical applications
Astrophysical observations are pointing out huge amounts of “dark matter” and “dark energy” needed to explain the observed large scale structure and cosmic dynamics. The emerging picture is a
Testing Gravity Using Galaxy Clusters: New Constraints on Beyond Horndeski Theories
The Beyond Horndeski class of alternative gravity theories allow for Self-accelerating de-Sitter cosmologies with no need for a cosmological constant. This makes them viable alternatives to
Testing general relativity with present and future astrophysical observations
One century after its formulation, Einstein's general relativity (GR) has made remarkable predictions and turned out to be compatible with all experimental tests. Most of these tests probe the theory
Evading equivalence principle violations, cosmological, and other experimental constraints in scalar field theories with a strong coupling to matter
We show that, as a result of nonlinear self-interactions, it is feasible, at least in light of the bounds coming from terrestrial tests of gravity, measurements of the Casimir force and those
The observational status of Galileon gravity after Planck
We use the latest CMB data from Planck, together with BAO measurements, to constrain the full parameter space of Galileon gravity. We constrain separately the three main branches of the theory known
Planck 2015 results: XIV. Dark energy and modified gravity
We study the implications of Planck data for models of dark energy (DE) and modified gravity (MG) beyond the standard cosmological constant scenario. We start with cases where the DE only directly
