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 …
Despite the fact that a rigid ${\rm {\Lambda}} $-term is a fundamental building block of the concordance ΛCDM model, we show that a large class of cosmological scenarios with …
Despite the outstanding achievements of modern cosmology, the classical dispute on the precise value of H 0, which is the first ever parameter of modern cosmology and one of the …

Stability analysis of interacting dark-energy models generally divides its parameters space into two regions,(i) wx≥-1 and ξ≥ 0 and (ii) wx≤-1 and ξ≤ 0, where wx is the dark-energy …

In the background of a homogeneous and isotropic space-time with zero spatial curvature, we consider interacting scenarios between two barotropic fluids, one is the pressureless …
In this year, in which we celebrate 100 years of the cosmological term, Λ, in Einstein's gravitational field equations, we are still facing the crucial question whether Λ is truly a …
