QPO-Based Bayesian Constraints on Charged Particle Dynamics Around Magnetized Schwarzschild Black Holes
Zakaria. Ahal, Hasan El Moumni, Karima Masmar
We study the motion of charged particles with a magnetic dipole moment orbiting a Schwarzschild black hole immersed in an external paraboloidal magnetic field. The interaction betw…

Modeling HF-QPOs in Microquasars and AGNs: Charged Particles around Black Holes with CDM Halos
Zakaria Ahal, Hasan El Moumni, Karima Masmar
HF QPOs are among the most intriguing phenomena observed in LMXBs containing BHs or neutron stars. In this work, we investigate charged particles' dynamics in the nearby of a Schwa…
