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 …

Early dark energy can resolve the Hubble tension
Early dark energy (EDE) that behaves like a cosmological constant at early times (redshifts
z≳ 3000) and then dilutes away like radiation or faster at later times can solve the Hubble …
