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…

Characterizing Power Spectra of Density Fluctuations in GRMHD Simulations of Black Hole Accretion Using Taylor's Frozen-in Hypothesis
Pravita Hallur, Lia Medeiros, Pierre Christian +1
We characterize the spatial power spectrum of density fluctuations in magnetohydrodynamic flows in a suite of high-resolution, long-time-span general relativistic magnetohydrodynam…

Mass Transport, Turbulent Mixing, and Inflow in Black Hole Accretion
George N. Wong, Lia Medeiros, James M. Stone
We investigate mass transport, mixing, and disk evolution in non-radiative black hole accretion flows using Lagrangian tracer particles embedded in general relativistic magnetohydr…
