Modeling UV Radiation Feedback from Massive Stars: I. Implementation of Adaptive Ray Tracing Method and Tests
Jeong-Gyu Kim, Woong-Tae Kim, Eve C. Ostriker +1
We present an implementation of an adaptive ray tracing (ART) module in the Athena hydrodynamics code that accurately and efficiently handles the radiative transfer involving multi…
Molecular Gas Feeding the Circumnuclear Disk of the Galactic Center
Pei-Ying Hsieh, Patrick M. Koch, Paul T. P. Ho +5
The interaction between a supermassive black hole (SMBH) and the surrounding material is of primary importance in modern astrophysics. The detection of the molecular 2-pc circumnuc…
Tracing the Spiral Structure of the Outer Milky Way with Dense Atomic Hydrogen Gas
Bon-Chul Koo, Geumsook Park, Woong-Tae Kim +3
We present a new face-on map of dense neutral atomic hydrogen (HI) gas in the outer Galaxy. Our map has been produced from the Leiden/Argentine/Bonn (LAB) HI 21-cm line all-sky sur…
Nuclear Spiral Shocks and Induced Gas Inflows in Weak Oval Potentials
Woong-Tae Kim, Bruce G. Elmegreen
Nuclear spirals are ubiquitous in galaxy centers. They exist not only in strong barred galaxies but also in galaxies without noticeable bars. We use high-resolution hydrodynamic si…
Origin of Non-axisymmetric Features of Virgo Cluster Early-type Dwarf Galaxies. I. Bar Formation and Recurrent Buckling
SungWon Kwak, Woong-Tae Kim, Soo-Chang Rey +1
A fraction of early-type dwarf galaxies in the Virgo cluster have a disk component and even possess disk features such as bar, lens, and spiral arms. In this study, we construct 15…
