We review recent developments and results in testing general relativity (GR) at cosmological
scales. The subject has witnessed rapid growth during the last two decades with the aim of …

Mimetic gravity is a Weyl‐symmetric extension of General Relativity, related to the latter by a
singular disformal transformation, wherein the appearance of a dust‐like perfect fluid can …

We investigate the D→ 4 limit of the D-dimensional Einstein-Gauss-Bonnet gravity, where
the limit is taken with α˜=(D− 4) α kept fixed and α is the original Gauss-Bonnet coupling …

We present a turnkey solution, ready for implementation in numerical codes, for the study of
linear structure formation in general scalar-tensor models involving a single universally …

A bstract Poincaré invariance is a well-tested symmetry of nature and sits at the core of our
description of relativistic particles and gravity. At the same time, in most systems Poincaré …

We explore the cosmological solutions of a recently proposed extension of general relativity
with a Lorentz-invariant mass term. We show that the same constraint that removes the …

Hořava's quantum gravity at a Lifshitz point is a theory intended to quantize gravity by using
traditional quantum field theories. To avoid Ostrogradsky's ghosts, a problem that has been …

Motivated by the holographic principle, it has been suggested that the dark energy density
may be inversely proportional to the area of the event horizon of the Universe. However …

We study the nonlinear evolution of baryon acoustic oscillations in the dark matter power
spectrum and the correlation function using renormalized perturbation theory. In a previous …
