On Accretion and Neutrino Investigations of Thermodynamically Reconstructed Black Holes from Three-Parameter Generalized Entropy

F. Barzi, W. El Hadri, H. El Moumni +2

We study accretion and neutrino-sensitive thermal signatures of a static black hole reconstructed from a three-parameter generalized entropy. The construction is thermodynamic by d…

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…

Modified Unruh Thermodynamics in Emergent Gravity: Finite Heat Capacity and Rényi Entropy

F. Barzi, H. El Moumni, K. Masmar

We show that Jacobson's thermodynamic derivation of Einstein's equations remains valid when local Rindler horizons are treated as finite heat-capacity systems, resolving the unphys…

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…

On Rényi Microstructural Aspects of Asymptotically Flat Charged Black Holes: A Novel Duality

F. Barzi, H. El Moumni, K. Masmar

We explore the microstructure of asymptotically flat charged black holes through the lens of nonextensive Rényi statistics. A modified form of the Rényi entropy is proposed to in…

On M87 and SgrA Observational Constraints of Dunkl Black Holes

N. Askour, A. Belhaj, L. Chakhchi +2

In this work, we investigate the optical properties of a new black hole recently obtained from the Dunkl operator formalism involving a relevant parameter denoted by . Concrete…
