Description

In this project I investigate how the inclination of the initial magnetic field affects MRI development in astrophysical accretion disks, using an electron-positron pair plasma approach. Previous studies have mostly considered vertical fields, leaving the role of oblique or toroidal fields unexplored in 3D kinetic simulations. By varying the magnetic field inclination, I study how geometry influences MRI growth, angular-momentum transport, and non-thermal particle acceleration. The goal of this research is to provide insights into the importance of the magnetic field’s initial configuration for kinetic plasma dynamics in accretion disks, improving our understanding of turbulence, particle energization, and the conditions that may lead to high-energy radiation in extreme astrophysical environments.
