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…
Light Trajectories and Thermal Shadows casted by Black Holes in a Cavity
A. Belhaj, H. Belmahi, M. Benali +2
We explore the shadows and the photon rings casted by black holes in cavity. Placing the observer inside such an isothermal background, we examine the influence of the cavity tempe…
Light Deflection by Rotating Regular Black Holes with a Cosmological Constant
A. Belhaj, H. Belmahi, M. Benali +1
Using the Gauss-Bonnet theorem, we compute and examine the deflection angle of light rays by rotating regular black holes with a cosmological constant. By the help of optical geome…
Light Deflection Angle by Superentropic Black Holes
A. Belhaj, H. Belmahi, M. Benali +1
Motivated by recent works on light deflection and shadow behaviors on AdS geometries, we investigate the deflection angle of light rays by superentropic black holes. Taking appropr…
