We systematically review some standard issues and also the latest developments of
modified gravity in cosmology, emphasizing on inflation, bouncing cosmology and late-time …

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 …

The strong discrepancy between local and early-time (inverse distance ladder) estimates of
the Hubble constant H 0 could be pointing towards new physics beyond the concordance Λ …

We investigate the observational consequences of a novel class of stable interacting dark
energy (IDE) models, featuring interactions between dark matter (DM) and dark energy (DE) …

Mimetic gravity has gained significant appeal in cosmological contexts, but static spherically
symmetric space-times within the baseline theory are highly non-trivial: the two natural …

Persisting tensions between high-redshift and low-redshift cosmological observations
suggest the dark energy sector of the Universe might be more complex than the positive …

In attempts to unify the four known fundamental forces in a single quantum-consistent theory,
it is suggested that Lorentz symmetry may be broken at the Planck scale. Here we search for …

We consider the recently proposed possibility that dark energy (DE) and baryons may
scatter through a pure momentum exchange process, leaving the background evolution …

This paper is dedicated to assessing modified cosmological settings based on the
gravitational Standard-Model Extension (SME). Our analysis rests upon the Hubble tension …
