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…
Revisiting diagonal tetrads: New Black Hole solutions in gravity
Adel Awad, Alexey Golovnev, María-José Guzmán +1
We study various forms of diagonal tetrads that accommodate Black Hole solutions in gravity with certain symmetries. As is well-known, vacuum spherically symmetric diagonal…
Topological dyonic Taub-Bolt/NUT-AdS: Thermodynamics and first law
Adel Awad, Somaya Eissa
Motivated by the absence of Misner string in the Euclidean Taub-Bolt/NUT solutions with flat horizons, we present a new treatment for studying the thermodynamics of these spactimes…
Degenerate Bogdanov-Takens bifurcations in a bulk viscous cosmology
Asmaa Abdel Azim, Adel Awad, E. I. Lashin
Using the dynamical system theory we show that the Friedmann-Robertson-Walker (FRW) cosmological model with bulk viscous fluid in the presence of cosmological constant is equivalen…
Viability of bouncing cosmology in energy-momentum-squared gravity
Ahmed H. Barbar, Adel M. Awad, Mohammad T. AlFiky
We analyze the early-time isotropic cosmology in the so-called energy-momentum-squared gravity (EMSG). In this theory, a term is added to the Einstein-Hilbert action…
Generalized teleparallel cosmology and initial singularity crossing
Adel Awad, Gamal Nashed
We present a class of cosmological solutions for a generalized teleparallel gravity with, , where is some parameter and is an integer or half-in…
