Numerical Simulations of a Protostellar Outflow Colliding with a Dense Molecular Cloud (2008)
Baek, Chang Hyun, Kim, Jongsoo, Choi, Minho
High-resolution SiO observations of the NGC 1333 IRAS 4A star-forming region showed a highly collimated outflow with a substantial deflection. The deflection was suggested to be caused by the...
How was the mushroom-shaped GW 123.4--1.5 formed in the Galactic disk? (2008)
Baek, Chang Hyun, Kudoh, Takahiro, Tomisaka, Kohji
The unusual mushroom-shaped HI cloud, GW 123.4--1.5, is hundreds of parsecs in size but does not show any correlations to HI shells or chimney structures. To investigate the origin and velocity...

Thermal-gravitational instability (TGI) is studied in the protogalactic environment. We extend our previous work, where we found that dense clumps first form out of hot background gas by thermal...
Baek, Chang Hyun, Kang, Hyesung, Kim, Jongsoo, Ryu, Dongsu
We study thermal-gravitational instability in simplified models for protogalactic halos using three-dimensional hydrodynamic simulations. The simulations followed the evolution of gas with radiative...
Two-Dimensional Axisymmetric Collapse of Thermally Unstable Primordial Clouds (2002)
Baek, Chang Hyun, Kang, Hyesung, Ryu, Dongsu
We have performed two-dimensional hydrodynamic simulations of the collapse of isolated axisymmetric clouds condensing via radiative cooling in a primordial background gas. In order to study the...
