Dyonic Taub-NUT-AdS Black Branes: Thermodynamics and Phase Diagrams
Amr AlBarqawy, Adel Awad, Esraa Elkhateeb +1
Motivated by the recent developments in the thermodynamics of Taub-NUT spaces and the absence of Misner strings in Taub-NUT solutions with flat horizons, we investigated the phase…
A preference for dynamical phantom dark energy using one-parameter model with Planck, DESI DR1 BAO and SN data
Ramy Fikri, Esraa Elkhateeb, E. I. Lashin +1
Baryon Acoustic Oscillation (BAO) provides a powerful tool to measure cosmic expansion and consequently the nature of the Dark Energy (DE). Recent precise BAO measurements by Dark…
Dyonic Taub-NUT-AdS Spaces: Phase Structures of all Horizon Geometries
Mohamed Tharwat, Amr AlBarqawy, Adel Awad +1
We study phase structures of Lorentzian Dyonic Taub-NUT-AdS spacetimes for different horizon geometries, which are spherical, flat, and hyperbolic. We check the consistency of our…
Dyonic Taub-NUT-AdS: Unconstraint Thermodynamics and Phase Structure
Adel Awad, Esraa Elkhateeb
Here we extend the approach developed in \cite{adel_2} to study the thermodynamics of Taub-NUT-AdS and dyonic Taub-NUT-AdS solutions. Furthermore, we investigate in details the pos…
Reconstruction of Gravity from Cosmological Unified Dark Fluid Model
Esraa Ali Elkhateeb
In this work, we reconstruct the cosmological unified dark fluid model proposed previously by Elkhateeb \cite{Elkhateeb:2017oqy} in the framework of gravity. Utilizing the e…
Modified hybrid inflation, reheating and stabilization of the electroweak vacuum
Merna Ibrahim, Mustafa Ashry, Esraa Elkhateeb +2
We propose a modification to the standard hybrid inflation model \cite{Linde:1993cn}, that connects a successful hybrid inflation scenario to the standard model Higgs sector, via t…
Dissipative Unified Dark Fluid: Observational Constraints
Esraa Ali Elkhateeb, Mahmoud Hashim
We adopt a standard FRW cosmology with a unified scenario, where the usual dark matter and dark energy sectors are replaced by a single dissipative unified dark fluid (DUDF). The e…
Dissipative Unified Dark Fluid Model
Esraa Elkhateeb
We consider a unified dissipative dark fluid model. Our fluid contains an adiabatic part plus a bulk viscous one. The adiabatic part has the ability to asymptote between two power…
A Viable Dark Fluid Model
Esraa Elkhateeb
We Consider a cosmological model based on a generalization of the equation of state proposed by Nojiri and Odintsov [46] and Štefanči'c [47], [48]. We argue that this model works a…
