Numerical Simulation of Hot Accretion Flows. IV. Effects of Black Hole Spin and Magnetic Field Strength on the Wind and the Comparison between Wind and Jet Properties

This is the fourth paper of our series works studying winds from hot accretion flows around black holes. In first two papers, we have shown existence strong in using hydrodynamical and magnetohydrodynamical (MHD) simulations. third paper, by three dimensional general relativity MHD numerical simulation data adopting a "virtual particle trajectory" analysis approach, calculated properties wind, such as its mass flux velocity. However, that focuses only on non-spinning hole SANE (standard normal accretion). present extend including cases rapidly rotating MAD (magnetically arrested disk). We focus investigating effect spin magnetic field wind jet. It found larger stronger usually enhance The formulae describing flux, poloidal velocity, fluxes momentum, kinetic energy, total energy jet are presented. One interesting finding, among others, even case very spinning where supposed to be strongest, momentum smaller than while at most factor 10. result suggests potentially plays more important role least for some problems active galactic nuclei feedback.
