Conditions for Bar Formation in Bulgeless Disk Galaxies
Dajeong Jang, Woong-Tae Kim, Yun Hee Lee
While bars are commonly observed in disk galaxies, the precise conditions governing their formation remain incompletely understood. To investigate these conditions, we perform a su…

Dissecting Bar-Induced Stellar Kinematics in Disk Galaxies: The Bisymmetric Model and Rotation Curve Modifications
Seungwon Baek, Woong-Tae Kim, Dajeong Jang +1
We analyze bars formed in -body simulations to investigate two key aspects of stellar kinematic structure of barred galaxies: the angular distributions of the radial and azimuth…

Effects of Halo Spin on Bar Formation in Disk Galaxies
Dajeong Jang, Woong-Tae Kim
The spin of dark halos has been shown to significantly affect bar formation and evolution in disk galaxies. To understand the physical role of the halo spin on bar formation, we ru…
