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
few years as the accuracy of cosmological observations improves. In this review we discuss …

Dark matter and dark energy interactions: theoretical challenges, cosmological implications and observational signatures
Abstract Models where dark matter and dark energy interact with each other have been
proposed to solve the coincidence problem. We review the motivations underlying the need …

Nonminimal dark sector physics and cosmological tensions
We explore whether nonstandard dark sector physics might be required to solve the existing
cosmological tensions. The properties we consider in combination are (a) an interaction …

Can interacting dark energy solve the tension?
E Di Valentino, A Melchiorri, O Mena - Physical Review D, 2017 - APS
The answer is yes. We indeed find that interacting dark energy can alleviate the current
tension on the value of the Hubble constant H 0 between the cosmic microwave background …

Indications of a late-time interaction in the dark sector
We show that a general late-time interaction between cold dark matter and vacuum energy
is favored by current cosmological data sets. We characterize the strength of the coupling by …
