Hiroshi Koyama's Research
I'm interested in the physical processes in interstellar medium (ISM) that lead to formation of molecular clouds. My research consists of theoretical studies that include linear stability analysis and nonlinear magneto/hydrodynamical calculations. A part of my work has been dedicated to developing and implementing numerical code for vector and parallel supercomputer. |

Giant Molecular Clouds (GMCs) in Galactic ISM Another relevant source of galactic scale turbulence is stellar feedback. Eve Ostriker and I have been developing the numerical models for galactic ISM and HII regions as the stellar feedback. The self-gravitating, multiphase gas disk is simulated in a local shearing periodic box. The simulations resolve formation and disruption of GMCs controlled by the turbulence. |
