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

E Abdalla, GF Abellán, A Aboubrahim, A Agnello… - Journal of High Energy …, 2022 - Elsevier
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 …

Challenges for ΛCDM: An update

L Perivolaropoulos, F Skara - New Astronomy Reviews, 2022 - Elsevier
A number of challenges to the standard Λ CDM model have been emerging during the past

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 …

Hubble tension: The evidence of new physics

JP Hu, FY Wang - Universe, 2023 - mdpi.com

Inflation, the Hubble tension, and early dark energy: An alternative overview

W Giarè - Physical Review D, 2024 - APS
I review and discuss the possible implications for inflation resulting from considering new
physics in light of the Hubble tension. My study is motivated by a simple argument that the …

Model-independent reconstruction of the interacting dark energy kernel: Binned and Gaussian process
