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 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 …

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 …

We present a further observational analysis of the Λ s CDM model proposed in Akarsu et
al.[Phys. Rev. D 104, 123512 (2021) PRVDAQ 2470-0010 10.1103/PhysRevD …

The f (Q) theories of modified gravity arise from the consideration of non-metricity as the
basic geometric quantity, and have been proven to be very efficient in describing the late …

Measurements of the H 0 and σ 8 parameters within the standard cosmological model
recently highlighted significant statistical tensions between the cosmic microwave …

In this paper, we consider the effects of adding curvature in extended cosmologies involving
a free-to-vary neutrino sector and different parametrizations of dark energy (DE). We make …

A substantial body of phenomenological and theoretical work over the last few years
strengthens the possibility that the vacuum energy density (VED) of the universe is …
