平滑粒子流体动力学(SPH)数值模拟中的重子物理
Baryonic Physics in Cosmological Smoothed Particle Hydrodynamics Simulations
摘要
Abstract
The smoothed particle hydrodynamics (SPH) simulation is a powerful tool in studying galaxy formation and evolution. In this review, standard formulation of SPH is summarized. And then the implementation of baryonic physics in cosmological SPH simulations are illustrated, including star formation, galactic wind feedback, AGN feedback, and thermal conduction. uring the past years, much progress has been made on improving the physical modeling in hydro dynamical simulations, by nvoking more sophisticated treatments of star formation, supernovae feedback, AGN feedback and so on. The implementation of these baryonic physics in SPH simulations has helped us a lot in understanding how galaxies form and evolve in the universe. However, due to our limited knowledge of these baryonic physics, these models, are still far from being perfect. Many further studies are therefore needed in future to improve these physical modeling in simulations.关键词
