Deflection angle and shadow of slowly rotating black holes in galactic nuclei
A. El Balali, M. Benali, M. Oualaid
In this paper, we construct the slowly rotating case of an asymptotically flat supermassive black hole embedded in dark matter using Newman-Janis procedure. Our analysis is carried…

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…

Reconstructing slow-roll Scalar-Tensor Gauss-Bonnet single field inflation from running spectral data
A. Belhaj, H. Es-Sobbahi, M. Oualaid +1
We examine cosmological inflation in a broad family of scalar-tensor models characterized by scalar-dependent non minimal kinetic couplings and Gauss-Bonnet terms. Using a slow rol…
