| Abstract: |
High-resolution numerical simulations reveal gas structure and dynamics on a sub-pc scale in a circum nuclear starburst region. Thick disks interlaced with fillaments, clumps and holes are naturally formed due to interplay among energy feedback from supernovae, self-gravity of the gas, galactic rotation, and radiative cooling. As a result of the inhomogeneous and turbulent structure of the ISM around the AGN, mass accretion to the nuclear pc region is not steady, but it fluctuates over two orders of magnitude. Using the hydrodynamical models, we have performed three-dimensional, non-LTE radiative transfer calculations for molecular lines. The inhomogeneous structure of the circum nuclear disk could be resolved with future observations with mm/sub-mm molecular lines using ALMA. |
