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 …

Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

We consider a variant of the Nojiri–Odintsov covariant Hořava-like gravitational model,
where diffeomorphism invariance is broken dynamically via a non-standard coupling to a …

The main objective of this article is to examine the stability of Einstein static universe using
inhomogeneous perturbations in the context of energy–momentum squared gravity. For this …

In order to bypass the big bang singularity, we develop an emergent universe scenario
within a covariant extension of General Relativity known as “Energy–Momentum Squared …

We examine the phase space of Hořava–Lifshitz cosmology for a wide range of self-
interacting potentials for the scalar field under the detailed-balance condition and without …

We consider the existence and stability of the Einstein static universe under the Generalized
Uncertainty Principle (GUP) effects. We show that this solution in the presence of perfect …

Non-singular cosmological models, particularly the idea of emergent cosmology have been
explored to describe the non-singular origin of the Universe. Recently, zero-point length …

We investigate the realization of the emergent universe scenario in theories with natural UV
cutoffs, namely a minimum length and a maximum momentum, quantified by a new …

The emergent scenario provides a possible way to avoid the big bang singularity by
assuming that the Universe originates from an Einstein static state. Therefore, an Einstein …
