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…
How Holographic is the Dark Energy? A Spline Nodal reconstruction approach
Miguel A. Zapata, Gabriela Garcia-Arroyo, Shahnawaz A. Adil +1
The paper investigates a generalized holographic dark energy model by reconstructing its density‑horizon relation with a spline‑based non‑parametric function and tests it against c…
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…
Updated Constraints on Omnipotent Dark Energy: A Comprehensive Analysis with CMB and BAO Data
Enrico Specogna, Shahnawaz A. Adil, Emre Ozulker +4
In this work, we present updated observational constraints on the parameter space of the DMS20 dark energy model, a member of the omnipotent dark energy (ODE) class. Our analysis c…
