Background-level reconstruction of scalar-field potentials from dark-energy histories and comparison with analytic potential families
Shahnawaz A. Adil, Miguel A. Zapata, Ãzgür Akarsu +1
The paper introduces a framework to reconstruct scalar‑field potentials that reproduce a given dark‑energy density history in a flat FLRW universe, applies it to several benchmark…
Dissipative Cosmology and the Nature of Dark Energy: Insights from Bulk Viscosity with DESI DR2 observations
Shahnawaz A. Adil, Sonej Alam, Somasri Sen +1
We explore a cosmological model in which dark energy is described by a bulk viscous fluid, providing a dissipative mechanism for late-time cosmic acceleration. Considering both min…
CDM cosmology from a type-II minimally modified gravity
Ãzgür Akarsu, Antonio De Felice, Eleonora Di Valentino +5
We integrate CDM, a promising scenario for alleviating cosmological tensions, into VCDM, a type-II minimally modified gravity. This promotes the scenario to a fully pre…
Exploring the Growth-Index () Tension with CDM
Luis A. Escamilla, Ãzgür Akarsu, Eleonora Di Valentino +2
Recent observational analyses have revealed a significant tension in the growth index , which characterizes the growth rate of cosmic structures. Specifically, when treating $Î…
Testing an oscillatory behavior of dark energy
Luis A. Escamilla, Supriya Pan, Eleonora Di Valentino +3
The main aim of this work is to use a model-independent approach, along with late-time observational probes, to reconstruct the dark energy (DE) equation of state .…
Cosmological constraints on CDM scenario in a type II minimally modified gravity
Ãzgür Akarsu, Antonio De Felice, Eleonora Di Valentino +5
The idea of a rapid sign-switching cosmological constant (mirror AdS-dS transition) in the late universe at , known as the CDM model, has significantly improv…
