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…
