Thermal Stability of Radiation-Pressure-Dominated Accretion Disks Threaded by Net Vertical Magnetic Flux
Shahram Abbassi, Armin Memarian, Samik Mitra
The classical radiation-pressure instability predicts strong thermal variability in luminous black-hole accretion disks, whereas most disk-dominated X-ray binary soft states remain…
The Galactic Center as a connected ecosystem across spatial and temporal scales
Michal ZajaÄek, Bożena Czerny, Martin Mondek +5
The Galactic Center is not only the region where the nearest supermassive black hole (SMBH) is located. It is also the region with the largest stellar density as well as the larges…
Properties of low angular momentum general relativistic MHD accretion flows around black holes
Samik Mitra
In this proceeding, we provide a novel approach to study the General Relativistic Magnetohydrodynamic (GRMHD) accretion flows around rotating black holes (BHs). In doing so, we cho…
Low angular momentum general relativistic magnetohydrodynamic accretion flow around rotating black holes with shocks
Samik Mitra, Santabrata Das
We investigate the global structure of general relativistic magneto-hydrodynamic (GRMHD) accretion flows around Kerr black holes containing shock waves, where the disk is threaded…
Accretion flows around spinning compact objects in the post-Newtonian regime
Elham Nazari, Samik Mitra, Shahram Abbassi +1
We present the structure of a low angular momentum accretion flows around rotating compact objects incorporating relativistic corrections up to the leading post-Newtonian order. To…
