Impact of Rastall gravity on mass, radius and sound speed of the pulsar PSR J0740+6620
Waleed El Hanafy
Millisecond pulsars are perfect laboratories to test possible matter-geometry coupling and its physical implications in light of recent Neutron Star Interior Composition Explorer (…
Non-trivial class of anisotropic compact stellar model in Rastall gravity
G. G. L. Nashed, W. El Hanafy
We investigated Rastall gravity, for an anisotropic star with a static spherical symmetry, whereas the matter-geometry coupling as assumed in Rastall Theory (RT) is expected to pla…
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…
Phenomenological Reconstruction of Teleparallel Gravity
W. El Hanafy, G. G. L. Nashed
We present a novel reconstruction method of teleparallel gravity from phenomenological parameterizations of the deceleration parameter or other alternatives. This can be use…
Einstein Geometrization Philosophy and Differential Identities in PAP-Geometry
M. I. Wanas, Nabil L. Youssef, W. El Hanafy +1
The importance of Einstein's geometrization philosophy, as an alternative to the least action principle, in constructing general relativity (GR), is illuminated. The role of differ…
Graceful Exit Inflation in Gravity
G. G. L. Nashed, W. El Hanafy, Sh. Kh. Ibrahim
We apply a quadratic teleparallel torsion scalar of the field equations to the spatially flat Friedmann-Robertson-Walker (FRW) model. We assume two perfect fluid co…
