Nature of the Wiggle Instability of Galactic Spiral Shocks
Woong-Tae Kim, Yonghwi Kim, Jeong-Gyu Kim
Gas in disk galaxies interacts nonlinearly with an underlying stellar spiral potential to form galactic spiral shocks. While numerical simulations typically show that spiral shocks…

Gaseous Spiral Structure and Mass Drift in Spiral Galaxies
Yonghwi Kim, Woong-Tae Kim
We use hydrodynamic simulations to investigate nonlinear gas responses to an imposed stellar spiral potential in disk galaxies. The gaseous medium is assumed to be infinitesimally…
