Relativistic MHD Simulations of Poynting Flux-Driven Jets
Xiaoyue Guan, Hui Li, Shengtai Li
Relativistic, magnetized jets are observed to propagate to very large distances in many Active Galactic Nuclei (AGN). We use 3D relativistic MHD (RMHD) simulations to study the pro…
Testing Convergence for Global Accretion Disks
John F. Hawley, Sherwood A. Richers, Xiaoyue Guan +1
Global disk simulations provide a powerful tool for investigating accretion and the underlying magnetohydrodynamic turbulence driven by the magneto-rotational instability (MRI). Us…
Assessing Quantitative Results in Accretion Simulations: From Local to Global
John F. Hawley, Xiaoyue Guan, Julian H. Krolik
Discretized numerical simulations are a powerful tool for investigation of nonlinear MHD turbulence in accretion disks. However, confidence in their quantitative predictions requir…
Radially Extended, Stratified, Local Models of Isothermal Disks
Xiaoyue Guan, Charles F. Gammie
We consider local, stratified, numerical models of isothermal accretion disks. The novel feature of our treatment is that radial extent L_x and azimuthal extent L_y satisfy H << L_…
The Turbulent Magnetic Prandtl Number of MHD Turbulence in Disks
Xiaoyue Guan, Charles F. Gammie
The magnetic Prandtl number Pr_M is the ratio of viscosity to resistivity. In astrophysical disks the diffusion of angular momentum (viscosity) and magnetic fields (resistivity) ar…
Locality of MHD Turbulence in Isothermal Disks
Xiaoyue Guan, Charles F. Gammie, Jacob B. Simon +1
We numerically evolve turbulence driven by the magnetorotational instability (MRI) in a 3D, unstratified shearing box and study its structure using two-point correlation functions.…
