Abstract The standard Λ Cold Dark Matter (ΛCDM) cosmological model provides a good
description of a wide range of astrophysical and cosmological data. However, there are a …

A number of challenges to the standard Λ CDM model have been emerging during the past
few years as the accuracy of cosmological observations improves. In this review we discuss …

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 present an updated analysis of eleven cosmological models that may help reduce the
Hubble tension, which now reaches the 6σ level when considering the latest SH0ES …

Abstract We implement Crossing Statistics to reconstruct in a model-agnostic manner the
expansion history of the universe and properties of dark energy, using DESI Data Release 1 …

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

The LIGO and VIRGO Collaborations have recently announced the detection of gravitational
waves from a neutron star–neutron star merger (GW170817) and the simultaneous …

A bstract We study constraints from causality and unitarity on 2→ 2 graviton scattering in four-
dimensional weakly-coupled effective field theories. Together, causality and unitarity imply …

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 …

The understanding of stellar structure represents the crossroads of our theories of the
nuclear force and the gravitational interaction under the most extreme conditions observably …
