Symmetry and Conserved Quantities in -Gravity: Mei vs. Noether Approaches
Tahia F. Dabash, Moataz H. Emam, Lukas Schoppner
We study the symmetries and conserved quantities in gravity for the static, spherically symmetric Reissner--Nordström spacetime using two complementary frameworks: Noether s…
The geodesic structure of BPS one-branes in five dimensions
Tahia F. Dabash, Moataz H. Emam
In this paper, we continue previous work where one-brane spacetimes coupled to the N=2 ungauged five dimensional hypermultiplets were found. We explore their symmetries as well as…
Interpreting the Cosmic History of the Universe Through Five-Dimensional Supergravity
Moataz H. Emam, Safinaz Salem
Through modeling the universe as a symplectic 3-brane embedded in the bulk of N = 2 five-dimensional ungauged supergravity theory, the entire evolution of the universe can be inter…
Modeling Stellar Surface Features on Subgiant Star with an M-dwarf Companion
Maria C. Schutte, Leslie Hebb, Simon Lowry +7
Understanding magnetic activity on the surface of stars other than the Sun is important for exoplanet analyses to properly characterize an exoplanet's atmosphere and to further cha…
The Implications of N = 2 Supergravity Cosmology On the Topology of the Calabi-Yau Manifold
Safinaz Salem, Moataz H. Emam, H. H. Salah
When N= D=11 supergravity is compactified on CY threefold to N=2 D=5 supergravity the action of the last is given in terms of the geometery of the CY manifold space, namely, in ter…
Brane-Worlds and the Calabi-Yau Complex Structure Moduli
Moataz H. Emam, H. H. Salah, Safinaz Salem
In this paper we extend previous work on the relation between the complex structure moduli of the underlying Calabi-Yau manifold in five dimensional supergravity with the time evol…
