Title: Galaxy Evolution on AMR Author(s): Ji-hoon Kim Abstract: We present a pipeline of putting galaxies on AMR (Adaptive Mesh Refinement) grids and following their collapses and mergers. One of the most fundamental challenges in structure formation is understanding the evolution of galaxies, but to fully model it with computers we need very high resolution simulations, as it is consistent of numerous constituent micro-processes occurring on a very wide range of distance scales: from ~Mpc (distance between the galaxies) to ~few pc (star forming regions.) Now thanks to the tremendous progress in computational resources and the help of parallel programming, we are now poised to realize these kinds of simulations. This pipeline that we are developing would allow us to investigate the structure formation and evolution ranging from the smallest dwarf galaxy formation to the Milky-Way type galaxy merger. Using this AMR technique, we can also bring the multiphase gas physics and stellar feedback back to the halo into play.
