Finite-Field QED Corrections to Vacuum Birefringence and Magnetar Polarization Transport
S. Abbassi, F. A. Chishtie, S. R. Valluri
We study low-energy photon propagation in a constant magnetic field within the finite-field one-loop Heisenberg--Euler framework and apply the resulting mode-dependent refractive i…
Bondi-like Accretion Flow Dynamics: The Role of Gravitational Potential
Razieh Ranjbar, Héctor R. Olivares-Sánchez, Shahram Abbassi
The formation of massive black holes and their coevolution with host galaxies are pivotal areas of modern astrophysics. Spherical accretion onto a central point mass serves as a fo…
Thermal instability of thin disk in the presence of wind and corona
Arezoo Tajmohamadi, Shahram Abbassi
This study investigates the thermal stability of thin accretion disks in high-energy astrophysical systems, incorporating the effects of magnetic fields, winds, and coronae. We ana…
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…
Slowly Rotating Accretion Flow Around SMBH in Elliptical Galaxy: Case With Outflow
Razieh Ranjbar, Shahram Abbassi
Observational evidence and many numerical simulations show the existence of wind (i.e., uncollimated outflow) in accretion systems of the elliptical galaxy center. One of the prima…
Global Transonic Solution of Hot Accretion Flow with Thermal Conduction
Samik Mitra, Sayyedeh Masoumeh Ghoreyshi, Amin Mosallanezhad +2
We examine the effect of thermal conduction on the low-angular momentum hot accretion flow (HAF) around non-rotating black holes accreting mass at very low rate. While doing so, we…
