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 …

We review the current status of Early Dark Energy (EDE) models proposed to resolve the
“Hubble tension”, the discrepancy between “direct” measurements of the current expansion …

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 …

Abstract The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders
about the fundamental theory of nature at play in the extreme gravity regime, where the …

Abstract LiteBIRD, the Lite (Light) satellite for the study of B-mode polarization and Inflation
from cosmic background Radiation Detection, is a space mission for primordial cosmology …

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 …

We present the cosmological implications from final measurements of clustering using
galaxies, quasars, and Ly α forests from the completed Sloan Digital Sky Survey (SDSS) …

Pulsar timing arrays (PTAs) have reported evidence for a stochastic gravitational wave (GW)
background at nanohertz frequencies, possibly originating in the early Universe. We show …

We present a joint cosmological analysis of weak gravitational lensing observations from the
Kilo-Degree Survey (KiDS-1000), with redshift-space galaxy clustering observations from …

We present a framework for self-consistent cosmological analyses of the full-shape
anisotropic bispectrum, including the quadrupole (ℓ= 2) and hexadecapole (ℓ= 4) moments …
