Hydrodynamical Simulations of Galaxy Clusters with Galcons

Understand

We present our recently developed {\em galcon} approach to hydrodynamical cosmological simulations of galaxy clusters - a subgrid model added to the {\em Enzo} adaptive mesh refinement code - which is capable of tracking galaxies within the cluster potential and following the feedback of their main baryonic processes.

• Galcons are physically extended galactic constructs within which baryonic processes are modeled analytically.
• By identifying galaxy halos and initializing galcons at high redshift ($z \sim 3$, well before most clusters virialize), we are able to follow the evolution of star formation, galactic winds, and ram-pressure stripping of interstellar media, along with their associated mass, metals and energy feedback into intracluster (IC) gas, which are deposited through a well-resolved spherical interface layer.
• Our approach is fully described and all results from initial simulations with the enhanced {\em Enzo-Galcon} code are presented.
