Evolution of the spin of late-type galaxies caused by galaxy-galaxy interactions
Jeong-Sun Hwang, Changbom Park, Soo-hyeon Nam +1
We use N-body/hydrodynamic simulations to study the evolution of the spin of a Milky Way-like galaxy through interactions. We perform a controlled experiment of co-planner galaxy-g…
Evolution of Late-type Galaxies in a Cluster Environment: Effects of High-speed Multiple Encounters with Early-type Galaxies
Jeong-Sun Hwang, Changbom Park, Arunima Banerjee +1
Late-type galaxies falling into a cluster would evolve being influenced by the interactions with both the cluster and the nearby cluster member galaxies. Most numerical studies, ho…
Hydrodynamic simulations of the central molecular zone with realistic Galactic potential
Jihye Shin, Sungsoo S. Kim, Junichi Baba +4
We present hydrodynamic simulations of gas clouds inflowing from the disk to a few hundred parsec region of the Milky Way. A gravitational potential is generated to include realist…
Effects of hot halo gas on the star formation and mass transfer during distant galaxy-galaxy encounters
Jeong-Sun Hwang, Changbom Park
We use -body/smoothed particle hydrodynamics simulations of encounters between an early-type galaxy (ETG) and a late-type galaxy (LTG) to study the effects of hot halo gas on th…
The initial conditions and evolution of isolated galaxy models: effects of the hot gas halo
Jeong-Sun Hwang, Changbom Park, Jun-Hwan Choi
We construct several Milky Way-like galaxy models containing a gas halo (as well as gaseous and stellar disks, a dark matter halo, and a stellar bulge) following either an isotherm…
Models of Stephan's Quintet: Hydrodynamic Constraints on the Group's Evolution
Jeong-Sun Hwang, Curtis Struck, Florent Renaud +1
We present smoothed particle hydrodynamic models of the interactions in the compact galaxy group, Stephan's Quintet. This work is extension of the earlier collisionless N-body simu…
