Understanding the large-scale formation is a paramount problem in modern cosmology. The galaxy clusters contain self-bound systems of galaxies, gas, and dark matter can be naturally treated as the fundamental structure of the cosmos. In this poster, we present the results from our simulations of the first galaxy cluster formation. We perform large-scale zoom-in cosmological simulations with GIZMO on a powerful supercomputer at NERSC. The cosmological initial condition is generated from MUSIC (MUlti-Scale Initial Conditions) code for the deeply nested region. Our simulations include much micro-physics such as self-gravity, star formation, turbulence, and gas cooling. Our goal is to understand the how the IGM gas, galaxies and dark matter affect the first galaxy cluster formation and to provide a physical interpretation for High-z observations.
