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 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 …

Singularities in any physical theory are either remarkable indicators of the unknown
underlying fundamental theory, or indicate a change in the description of the physical reality …

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 …

The early dark energy (EDE) solution to the Hubble tension comes at the cost of an
increased clustering amplitude that has been argued to worsen the fit to galaxy clustering …

We explore observational constraints on a cosmological model with an interaction between
dark energy (DE) and dark matter (DM), using a compilation of 15 measurements of the 2D …

We analyze a cosmological model featuring an interaction between dark energy and dark
matter in light of the measurements of the Cosmic Microwave Background released by three …

Measurements of weak gravitational lensing at low redshifts (z≲ 0.5–1), quantified by the
parameter S 8, favor weaker matter clustering than that expected from the standard Λ cold …

Analyses of the full shape of the Baryon Oscillation Spectroscopic Survey (BOSS) DR12
power spectrum using the one-loop prediction from the effective field theory of large-scale …
