Teleparallel gravity (TG) has significantly increased in popularity in recent decades, bringing
attention to Einstein's other theory of gravity. In this Review, we give a comprehensive …

This article is intended to review the recent developments in the Horndeski theory and its
generalization, which provide us with a systematic understanding of scalar–tensor theories …

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 …

In this work we present several characteristic examples of theories of gravity and particle
physics scenarios that may yield an observable energy spectrum of stochastic primordial …

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 propose a relativistic gravitational theory leading to modified Newtonian dynamics, a
paradigm that explains the observed universal galactic acceleration scale and related …

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 …

Non-linear electrodynamics (NLED) theories are well-motivated extensions of QED in the
strong field regime, and have long been studied in the search for regular black hole (BH) …

Abstract Recent Baryon Acoustic Oscillation (BAO) measurements released by DESI, when
combined with Cosmic Microwave Background (CMB) data from Planck and two different …

Searching for violations of the no-hair theorem (NHT) is a powerful way to test gravity, and
more generally fundamental physics, particularly with regards to the existence of additional …
