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 …

Challenges for ΛCDM: An update
A number of challenges to the standard Λ CDM model have been emerging during the past
few years as the accuracy of cosmological observations improves. In this review we discuss …

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 …

Can late-time extensions solve the and tensions?
L Heisenberg, H Villarrubia-Rojo, J Zosso - Physical Review D, 2022 - APS
We analyze the properties that any late-time modification of the Λ CDM expansion history
must have in order to consistently solve both the H 0 and the σ 8 tensions. Taking a model …

Is local H 0 at odds with dark energy EFT?
Local H_0 determinations currently fall in a window between H 0∼ 70 km/s/Mpc (TRGB) and
H 0∼ 76 km/s/Mpc (Tully-Fisher). In contrast, BAO data calibrated in an early ΛCDM …
