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 …

Consistency tests of from the early integrated Sachs-Wolfe effect: Implications for early-time new physics and the Hubble tension
S Vagnozzi - Physical Review D, 2021 - APS
New physics increasing the expansion rate just prior to recombination is among the least
unlikely solutions to the Hubble tension and would be expected to leave an important …
