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 …

The classical generalization of general relativity is considered as the gravitational alternative
for a unified description of the early-time inflation with late-time cosmic acceleration. The …

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 …

Recently Hořava proposed a renormalizable gravity theory in four dimensions which
reduces to Einstein gravity with a non-vanishing cosmological constant in IR but with …

We formulate Hořava–Lifshitz cosmology with an additional scalar field that leads to an
effective dark energy sector. We find that, due to the inherited features from the gravitational …

We investigate the scalar and tensor perturbations in Hořava gravity, with and without
detailed balance, around a flat background. Once both types of perturbations are taken into …

We investigate the new agegraphic dark energy scenario in a universe governed by Hořava-
Lifshitz gravity. We consider both the detailed and non-detailed balanced version of the …

Hawking radiation from the black hole in Hořava–Lifshitz gravity is discussed by a
reformulation of the tunneling method given in Banerjee and Majhi (2009)[17]. Using a …

We investigate the validity of the generalized second law of thermodynamics in a universe
governed by Hořava-Lifshitz gravity. Under the equilibrium assumption, that is in the late …

This paper is devoted to investigate the implications of Einstein-Aether and modified Hořava–
Lifshitz theories of gravity to the formation of light elements in the early universe named as …
