In this paper, we investigate the astrophysical processes of stellar-mass black holes
(sMBHs) embedded in advection-dominated accretion flows (ADAFs) of supermassive black …

Radiation RMHD accretion flows around spinning AGNs: a comparative study of MAD and SANE state

R Aktar, KC Pan, T Okuda - arXiv preprint arXiv:2406.10496, 2024 - arxiv.org
In our study, we examine a 2D radiation, relativistic, magnetohydrodynamics (Rad-RMHD)
accretion flows around a spinning supermassive black hole. We begin by setting an initial …
