Astrophysical Constraints on Charged Black Holes in Scalar--Tensor--Vector Gravity
Erdem Sucu, Kuantay Boshkayev, Yassine Sekhmani +2
We explore charged black holes in Scalar-Tensor-Vector Gravity (STVG), unveiling their distinctive features across multiple physical domains. Our topological analysis reveals that…

Quasinormal Modes of Massive Scalar Perturbations in Slow-Rotation Bumblebee Black Holes with Traceless Conformal Electrodynamics
Yassine Sekhmani, Wentao Liu, Weike Deng +1
We study electrically charged, slowly rotating black hole solutions in Einstein-Bumblebee gravity coupled to the traceless (conformal) ModMax nonlinear electrodynamics. By adopting…

Black holes immersed in polytropic scalar field gas
Y. Sekhmani, S. Zare, L. M. Nieto +2
By implementing the concept of polytropic structures as a scalar field gas with a dark energy-like behavior, we obtain a static spherically symmetric black hole solution in the fra…
