Deflection angle and Shadows by Black Holes in Starobinsky-Bel-Robinson Gravity from M-theory
A. Belhaj, H. Belmahi, M. Benali +2
Motivated by M-theory compactifications, we investigate optical properties of black holes in the Starobinsky-Bel-Robinsion gravity. Precisely, we study the shadows and the deflecti…
On Inflationary Models in f(R,T) Gravity with a Kinetic Coupling Term
A. Belhaj, M. Benali, Y. Hassouni +1
We investigate inflationary models in f(R,T) modified gravity with a kinetic coupling term ω^2 G^{μν}\partial_μϕ\partial_νϕhaving a positive factor needed to remove the ghosts. Tak…
Light Behaviors around Black Holes in M-theory
N. Askour, A. Belhaj, H. Belmahi +3
We study the deflection angle and the trajectory of the light rays around black holes in M-theory scenarios. Using the Gauss-Bonnet theorem, we first compute and examine the deflec…
Thermodynamic and Optical Behaviors of Quintessential Hayward-AdS Black Holes
A. Belhaj, M. Benali, H. El Moumni +3
Motivated by Dark Energy (DE) activities, we study certain physical behaviors of the quintessential Hayward-AdS black holes in four dimensions. We generalize some physical properti…
Superentropic Black Hole Shadows in Arbitrary Dimensions
A. Belhaj, M. Benali, Y. Hassouni
We investigate the shadow behaviors of the superentropic black holes in arbitrary dimensions. Using the Hamilton-Jacobi mechanism, we first obtain the associated null geodesic equa…
Deflection Light Behaviors by AdS Black Holes
A. Belhaj, H. Belmahi, M. Benali
We investigate the behavior of the deflection of light rays by charged and rotating AdS black holes using the Gauss-Bonnet formalism. Taking weak field approximations and certain a…
