We present for the first time a Friedmann-like construction in the framework of an osculating
Finsler–Randers–Sasaki (F–R–S) geometry. In particular, we consider a vector field in the …

We study scatterlike interactions between neutrinos and dark matter in light of different
combinations of temperature, polarization and lensing data released by three independent …

We investigated a possible interaction between cold dark matter and dark energy,
corresponding to a well-known interacting dark energy model discussed in the literature …

We do a detailed analysis of a well-theoretically motivated interacting dark energy scalar
field model with a time-varying interaction term. Using current cosmological datasets from …

This research investigates the impact of the nature of Dark Energy (DE) on structure
formation, focusing on the matter power spectrum and the Integrated Sachs–Wolfe effect …

We investigate the qualitative cosmic dynamics of varying vacuum models with the non-flat,
homogeneous and isotropic background. In these models, the dark matter interacts with the …

The very first light captured by the James Webb Space Telescope (JWST) revealed a
population of galaxies at very high redshifts more massive than expected in the canonical …

We place observational constraints on a dark energy (DE) model in which a quintessence
scalar field ϕ is coupled to dark matter (DM) through momentum and energy exchanges …

We analyse three interacting vacuum dark energy models with the aim of exploring whether
the H 0 and σ 8 tensions can be simultaneously resolved in such models. We present the …

In the present work, we perform a comparative study of different interacting dark energy (DE)
models using the Statefinder diagnostics. In particular, 17 different forms of the energy …
