A substantial body of phenomenological and theoretical work over the last few years
strengthens the possibility that the vacuum energy density (VED) of the universe is …

The cosmological dark sector remains an enigma, offering numerous possibilities for
exploration. One particularly intriguing option is the (non-minimal) interaction scenario …

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 …

Interacting dark energy models may play a crucial role in explaining several important
observational issues in modern cosmology and also may provide a solution to current …

In most cosmological models, the equation of state of the dark matter is assumed to be zero,
which means that the dark matter is pressure-less or cold. While this hypothesis is based on …

Dark energy is frequently modelled as an additional dynamical scalar field component in the
Universe, referred to as 'quintessence', which drives the late-time acceleration. Furthermore …

The next-generation cosmic microwave background (CMB) satellite missions are expected
to provide robust constraints on a wide range of cosmological parameters with …

In this paper, we have studied an interacting dark energy model. We have assumed the
gravitational interaction between the matter fields ie barotropic fluid and the dark energy …

We explore the bounds that can be placed on interactions between cold dark matter and
vacuum energy, with equation of state w=-1, using state-of-the-art cosmological …

This study examines interacting quintessence dark energy models and their observational
constraints for a general parameterization of the quintessence potential, which …
