Swampland Statistics for Black Holes
Saad Eddine Baddis, Adil Belhaj, Hajar Belmahi
In this work, we approach certain black hole issues, including remnants, by providing a statistical description based on the weak gravity conjecture in the swampland program. Inspi…
Optical Aspect of Cosmological Black Holes in Einstein-Maxwell-Dilaton Theory
Hajar Belmahi, Amin Mohamed Rbah
Motivated by string theory scenarios, we study the optical aspect of AdS black holes in Einstein-Maxwell-dilaton theory. Concretely, we investigate and examine the shadows and the…
Black Holes and Black Strings in M-theory on Calabi-Yau threefolds with four Kähler parameters
A. Belhaj, H. Belmahi, A. Bouhouch +2
Combining toric geometry techniques and supergravity formalisms, we study 5D black branes in the M-theory compactification on a four parameter Calabi-Yau threefold.…
Constrained Deflection Angle and Shadows of Rotating Black Holes in Einstein-Maxwell-scalar Theory
Hajar Belmahi
Motivated by recent Event Horizon Telescope findings, we investigate constrained optics of rotating black holes in Einstein-Maxwell-scalar gravity theory. Precisely, we mainly stud…
