Seven hints that early-time new physics alone is not sufficient to solve the Hubble tension
S Vagnozzi - Universe, 2023 - mdpi.com
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 …

Revealing the effects of curvature on the cosmological models
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 …
