We investigate interacting scenarios that belong to a wider class, since they include a
dynamical dark energy component whose equation of state follows various one-parameter …

The well-known tensions on the cosmological parameters H_0 H 0 and σ _8 σ 8 within the Λ
Λ CDM cosmology shown by the Planck-CMB and LSS data are possibly due to the …

We investigate an interacting dark sector scenario in which the vacuum energy is free to
interact with cold dark matter (CDM), which itself is assumed to cluster under the sole action …

We investigate various scenarios which include interaction forms between dark matter and
dark energy that exhibit sign reverse, namely where the transfer of energy between the dark …

Coupled dark matter–dark energy scenarios are modeled via a dimensionless parameter ξ,
which controls the strength of their interaction. While this coupling is commonly assumed to …

Investigations on dark energy (DE) are currently inconclusive about its time evolution. Hints
of this possibility do however glow now and then in the horizon. Herein we assess the …

We study a novel interacting dark energy− dark matter scenario where the anisotropic stress
of the large-scale inhomogeneities is considered. The dark energy has a constant equation …

We consider a class of interacting dark energy models in a flat and nonflat FLRW universe
where the interaction is characterized by the modified evolution of the pressureless dark …

Cosmological models where dark matter (DM) and dark energy (DE) interact with each other
are the general scenarios in compared to the non-interacting models. The interaction is …

Using the non-extensive Tsallis entropy and the holographic hypothesis, we propose a new
dark energy (DE) model with timescale as infrared (IR) cutoff. Considering the age of the …
