Plasmoid-Mediated 2D Magnetic Reconnection in Partially Ionized Plasmas
Yue Hu, Siyao Xu, Grzegorz Kowal +3
Magnetic reconnection in partially ionized plasmas is an important channel for energy release. While the plasmoid instability is well characterized in 2D fully ionized plasmas, its…
The SANE, the MAD, and the Chimera
George N. Wong, James M. Stone
Non-radiative black hole accretion flows are commonly classified by their magnetic flux state, with standard and normal evolution (SANE) disks and magnetically arrested disks (MADs…
Idealized Global Models of Accretion Disks with Strong Toroidal Magnetic Fields
Minghao Guo, Eliot Quataert, Jonathan Squire +2
We present global magnetohydrodynamic (MHD) simulations of idealized accretion disks with a strong toroidal magnetic field using an equation of state that fixes the gas thermal sca…
Is plasmoid-mediated reconnection really important in accretion flows to drive flares in AGNs?
Giovani H. Vicentin, Elisabete M. de Gouveia Dal Pino, George N. Wong +4
Based on very high-resolution resistive 2D and 3D magnetohydrodynamical (MHD) simulations of current sheets, our findings suggest that the answer to this question is likely no. In…
Cosmic Ray Perpendicular Superdiffusion and Parallel Mirror Diffusion in a Partially Ionized and Turbulent Medium
Yue Hu, Siyao Xu, Alex Lazarian +2
Understanding cosmic ray (CR) diffusion in a partially ionized medium is both crucial and challenging. In this study, we investigate CR perpendicular superdiffusion and parallel tr…
