Poloidal Field Amplification through Compression-Shear Dynamics in Schwarzschild Accretion: Pathways to MAD States
Malihe Mousapour Gharghabi, Jamshid Ghanbari, Mahboobe Moeen Moghaddas
The amplification of magnetic fields in black hole accretion flows governs key high-energy phenomena such as magnetically arrested disks and relativistic jets. We develop a semi-an…

A Study of thin relativistic magnetic accretion disk around a distorted black hole
Seyyed Masoud Hoseyni, Jamshid Ghanbari, Mahboobe Moeen Moghaddas
Accretion disks, swirling structures of matter spiraling into black holes, play a pivotal role in our understanding of binary star systems and their intricate evolutionary processe…

A Study of thin relativistic viscose accretion disk around a distorted kerr black hole (DKB)
Olya Layeghi, Jamshid Ghanbari, Mahboobe Moeen Moghaddas
In this paper, we analyze a thin disk around the distorted Kerr black hole (DKB) within the framework of general relativity using an axisymmetric solution of the Einstein equations…
