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 …

▪ The Hubble parameter, H 0, is not an univocally defined quantity: It relates redshifts to
distances in the near Universe, but it is also a key parameter of the ΛCDM standard …

The Hubble tension has now grown to a level of significance which can no longer be
ignored and calls for a solution which, despite a huge number of attempts, has so far eluded …

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 …

The dawn of the twenty-first century came with very positive prospects for gravity, cosmology,
and astrophysics. Technological progress made it possible for cosmology to enter to its …

The difference from 4 to 6 σ in the Hubble constant (H 0) between the values observed with
the local (Cepheids and Supernovae Ia, SNe Ia) and the high-z probes (Cosmic Microwave …

Abstract The standard Λ Cold Dark Matter cosmological model provides a wonderful fit to
current cosmological data, but a few statistically significant tensions and anomalies were …

We present evidence for a suppressed growth rate of large-scale structure during the dark-
energy-dominated era. Modeling the growth rate of perturbations with the “growth index” γ …

Early data from the James Webb Space Telescope (JWST) has uncovered the existence of a
surprisingly abundant population of very massive galaxies at extremely high redshift, which …
