Based mainly on X-ray observations, we study the interactions between the intracluster medium (ICM) in clusters of galaxies and their member galaxies. Through (magneto)hydrodynamic and gravitational channels, moving galaxies are expected to drag t...

We present the results of two-temperature magnetohydrodynamic simulations of the propagation of sub-relativistic jets of active galactic nuclei. The dependence of the electron and ion temperature distributions on the fract...
We present the results of global magnetohydrodynamic simulations of accretion disks by applying the HLLD scheme. The HLLD scheme extends the HLL scheme by using four intermediate states between the left state and the right state to handle the cont...
We performed two-dimentional radiation-hydrodynamic simulations of supercritical accretion onto a black hole including Compton scattering. We confirmed that the gas temperature in the outflow region decreases from 10^9-10^<11>K for the model witho...
We are developing a magnetohydrodynamic (MHD) simulator of the accretion disks using approximate Riemann solvers. We adopted HLLD scheme, because it is robust, easy to implement various physical processes, and has good convergence when the grid si...
