Gauss-Bonnet Gravity and Spacetime Singularities
Tariq Allaithy, Adel Awad, Mohamed Hany Radwan +1
We investigate the effect of higher-order curvature terms, specifically Gauss-Bonnet terms, on spacetime singularities in five dimensions. For FLRW cosmologies, we demonstrate that…
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…
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…
Motion of Spinning and Spinning Deviation Density Tensors in Riemannian Geometry
Magd E. Kahil, Samah A. Ammar, Shymaa A. Refaey
Equations of motion of spinning density for extended objects, and corresponding deviation equations are derived. The problem of motion for a variable mass to a spinning extended ob…
Gravitational Observations and LQGUP
Mohammed Hemeda, Hassan Alshal, Ahmed Farag Ali +1
Motivated by recent works, we employ the bounds on the dimensionless quantum-gravity parameter obtained from six gravitational tests in order to obtain bounds on the dimensionless…
