Effects of Magnetic Fields on Gas Dynamics and Star Formation in Nuclear Rings
Sanghyuk Moon, Woong-Tae Kim, Chang-Goo Kim +1
Nuclear rings at the centers of barred galaxies are known to be strongly magnetized. To explore the effects of magnetic fields on star formation in these rings and nuclear gas flow…
Effects of the Central Mass Concentration on Bar Formation in Disk Galaxies
Dajeong Jang, Woong-Tae Kim
While bars are common in disk galaxies, their formation conditions are not well understood. We use -body simulations to study bar formation and evolution in isolated galaxies co…
Effects of Varying Mass Inflows on Star Formation in Nuclear Rings of Barred Galaxies
Sanghyuk Moon, Woong-Tae Kim, Chang-Goo Kim +1
Observations indicate that the star formation rate (SFR) of nuclear rings varies considerably with time and is sometimes asymmetric rather than being uniform across a ring. To unde…
Star Formation in Nuclear Rings with the TIGRESS Framework
Sanghyuk Moon, Woong-Tae Kim, Chang-Goo Kim +1
Nuclear rings are sites of intense star formation at the centers of barred galaxies. To understand what determines the structure and star formation rate (SFR; ) o…
The Circumnuclear Disk Revealed by ALMA. I. Dense Clouds and Tides in the Galactic Center
Pei-Ying Hsieh, Patrick M. Koch, Woong-Tae Kim +8
Utilizing the Atacama Large Millimeter/submillimeter Array (ALMA), we present CS line maps in five rotational lines () toward the circumnuclear disk (CND)…
Local Simulations of Spiral Galaxies with the TIGRESS Framework: I. Star Formation and Arm Spurs/Feathers
Woong-Tae Kim, Chang-Goo Kim, Eve C. Ostriker
Spiral arms greatly affect gas flows and star formation in disk galaxies. We use local three-dimensional simulations of the vertically-stratified, self-gravitating, differentially-…
