The Star Universe Model -- Another FLRW Patch
Mustapha Azreg-A\"ınou
The Black Hole Universe model has advanced in the literature. It assumes that the whole mass of the Universe remains inside the Schwarzschild radius of a black hole after being sub…
Chaotic imprints of dark matter in extreme mass-ratio inspirals
Mustapha Azreg-Aïnou, Mubasher Jamil, Emmanuel N. Saridakis
Extreme mass-ratio inspirals (EMRIs) are among the most powerful probes of strong-field gravity and of the environments surrounding supermassive compact objects. Motivated by the e…
Exact Taub-NUT-like Black Holes in Einstein-bumblebee gravity: their thermodynamics and thermodynamic topology
Mustapha Azreg-Aïnou, Yassine Sekhmani
We re-derive an exact analytic three-parameter expressions for the non-rotating metric, describing a Taub-NUT-like black hole (BH), and its associated bumblebee field that are solu…
AdS black holes with primary Proca hair from a regularized Gauss-Bonnet coupling
Gokhan Alkac, Murat Mesta, Gonul Unal
We construct a consistent three-dimensional Einstein-Gauss-Bonnet theory as a vector-tensor theory within the generalized Proca class by employing a regularization procedure based…
Epicyclic oscillations and accretion disk around a special Buchdahl-inspired spacetime
Mirzabek Alloqulov, Mubasher Jamil, Sanjar Shaymatov +2
In this paper, we consider the Buchdahl-inspired spacetime metric and investigate its aspects using the quasiperiodic oscillations and the accretion disk due to the accreting matte…
Two-sided NED black-hole, naked-singularity, and soliton solutions
Mustapha Azreg-Aïnou
We consider non-linear electrodynamics (NED) minimally coupled to general relativity. We derive novel electrically charged, spherically symmetric, black-hole solutions having, for…
