Early observations with JWST have led to the discovery of an unexpectedly large density
(stellar-mass density ρ*≈ 10 6 M⊙ Mpc− 3) of massive galaxies (stellar masses M*≥ 10 …

One problem of the Λ CDM model is the tension between the S 8 found in Cosmic
Microwave Background (CMB) experiments and the smaller one obtained from large-scale …

We investigate the Tsallis holographic dark energy (THDE) models in the context of
perturbations' growth. We assume the description of dark energy by considering the …

We place novel constraints on the cosmokinetic parameters by using a joint analysis of the
newest Very Large Telescope (VLT)-K-band Multi Object Spectrograph (KMOS) HII galaxies …

In the era of precision cosmology, the cosmological constant Λ gives quite an accurate
description of the evolution of the Universe, but it is still plagued with the fine-tuning problem …

In this article, we elaborate further on the\varLambda Λ CDM “tension”, suggested recently
by the authors Lusso et al.(Astron Astrophys 628: L4, 2019) and Risaliti and Lusso (Nat …

In this work, we study the extended viscous dark energy models in the context of matter
perturbations. To do this, we assume an alternative interpretation of the flat Friedmann …

A cosmological model with an energy transfer between dark matter (DM) and dark energy
(DE) can give rise to comparable energy densities at the present epoch. The present work …

The evolution of the dark energy (DE) density is a crucial quantity for understanding the
nature of DE. Often, the quantity is described by the so-called equation of state; that is, the …
