The strong discrepancy between local and early-time (inverse distance ladder) estimates of
the Hubble constant H 0 could be pointing towards new physics beyond the concordance Λ …

We make the case that there can be no low-redshift solution to the H 0 tension. To robustly
answer this question, we use a very flexible parametrization for the dark energy equation of …

The Λ CDM model provides a good fit to most astronomical observations but harbors large
areas of phenomenology and ignorance. With the improvements in the precision and …

In this paper we explore the existing tensions in the local cosmological expansion rate, H 0,
and amplitude of the clustering of the large-scale structure at 8 h-1 Mpc, σ 8, as well as …

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 …

An only early or only late time alteration to Λ CDM has been inadequate at resolving both
the H 0 and S 8 tensions simultaneously; however, a combination of early and late time …

Phantom dark energy (w<-1) can produce amplified cosmic acceleration at late times, thus
increasing the value of H 0 favored by CMB data and releasing the tension with local …

The simplest ΛCDM model provides a good fit to a large span of cosmological data but
harbors large areas of phenomenology and ignorance. With the improvement of the number …

Despite the remarkable success of the Λ Cold Dark Matter (Λ CDM) cosmological model, a
growing discrepancy has emerged (currently measured at the level of∼ 4− 6 σ) between the …

Hubble tension is routinely presented as a mismatch between the Hubble constant H 0
determined locally and a value inferred from the flat Λ CDM cosmology. In essence, the …
