We carried out global three-dimensional magneto-hydrodynamic simulations of dynamo activities in galactic gaseous disks without assuming equatorial symmetry. Numerical results indicate the growth of azimuthal magnetic fields non-symmetric to the equa

We present global solutions of optically thin, two-temperature black hole accretion disks incorporating magnetic fields. We assume that the {\pi}{\phi}-component of the Maxwell stress is proportional to the total pressure, and prescribe the radial de

We obtained thermal equilibrium solutions for optically thin, two-temperature black hole accretion disks incorporating magnetic fields. The main objective of this study is to explain the bright/hard state observed during the bright/slow transition of

Observational study of galactic magnetic fields is limited by projected observables. Comparison with numerical simulations is helpful to understand the real structures, and observational visualization of numerical data is an important task. Machida e

Prompted by the discovery of pair-annihilation lines in Nova Muscae 1991, we calculated the emission line spectra of optically thin winds emanating from the inner region of a geometrically thin accretion disk. The line profiles are generally double p

Steady disk winds, or jets, from the inner region of a geometrically thin accretion disk were studied under the assumption that the wind flow is confined within a hollow cylindrical-shell region. By using the cold-wind approximation, in which the var
