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 …

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 …

Multimessenger gravitational-wave (GW) astronomy has commenced with the detection of
the binary neutron star merger GW170817 and its associated electromagnetic counterparts …

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

A century ago, Einstein formulated his elegant and elaborate theory of General Relativity,
which has so far withstood a multitude of empirical tests with remarkable success …

Abstract The Nobel Prize winning confirmation in 1998 of the accelerated expansion of our
Universe put into sharp focus the need of a consistent theoretical model to explain the origin …

The double copy is, in essence, a map between scattering amplitudes in a broad variety of
familiar field and string theories. In addition to the mathematically rich intrinsic structure, it …

We critically examine the state of current constraints on the dark energy (DE) equation of
state (EoS) w. Our study is motivated by the observation that, while broadly consistent with …

Gravitational waves (GWs) provide a new tool to probe the nature of dark energy (DE) and
the fundamental properties of gravity. We review the different ways in which GWs can be …

The gravitational wave (GW) event GW170817 from a binary neutron star merger together
with the electromagnetic counterpart showed that the speed of GWs ct is very close to that of …
