Cosmology intertwined: A review of the particle physics, astrophysics, and cosmology associated with the cosmological tensions and anomalies
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 …

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 …

Relaxing cosmological tensions with a sign switching cosmological constant
Inspired by the recent conjecture originated from graduated dark energy that the Universe
has recently transitioned from anti–de Sitter vacua to de Sitter vacua, we extend the …

f (Q, T) gravity models with observational constraints
The paper presents late time cosmology in f (Q, T) gravity where the dark energy is purely
geometric in nature. We start by employing a well motivated f (Q, T) gravity model, f (Q, T)= m …
